I personnally love long format videos, and if I need it chopped up into 15 min chunks I have convenient access to a pause button.

Marc when I think I’ve seen all your videos I dig an old one and always learn more. Thanks.

Bring it on! I'd love to hear Joe for an hour. There's always the pause button if I need a bathroom break!

Can't wait for that long video. Definitely enjoy and appreciate the time you put in to make these.

Will totally watch the longer video. I personally can't get enough reef related videos and you don't often see long format content. The beauty of KZfaq is you can always skip around a long video if it gets boring, but I don't see that happening for your upcoming post.

heck yeah i would totally want to see an hour long discussion with Joe and his amazing tank!!

A long video about reef tanks and some info is always good

I watched your interview on the 20,000 gallon reef. It was excellent. Top job

I would love to see the video in it's entirety. can't wait thank you for your hard work.

The hour long video was awesome, the longer they are the more information you can get thorugh.

Please put up the full one hour video! Great to watch and very easy to come back to if you need a break. I'll put it on my big screen and just sit back relax while I watch. Thanks for the effort so the rest have amazing videos to watch! - Mark-

Long videos.. short videos.. it doesn't matter all your videos are very well done and helps many people from a rookie that is learning his way into the hobbie or gives new ideas to experts, specially with a videos like this one, its great to review or learn your methods.Thank you for the time you spend doing your videos.. big fan.

I'm definitely willing to watch an hour long video about tanks. Love all of your stuff!

I enjoy longer videos as well. If I need to pause them and come back to it I can. I learn a lot about reef keeping from KZfaq (I only watch people that have been in the hobby for many years and have seen or done it all lol) keep up the great work. Looking forward to that video!

Please post the LI Aquarium video, everyone needs to see it. Joe is the coolest dude ever, over the summer in 2013 I drove to LI with my wife and daughters from the Bronx and it was about a 2 hour trip just to see this aquarium after I read a 2007 article he published in Advanced Aquarist about it. When I saw him walk out from the maintenance area I told him what we did and he said "well that deserves a tour!" And he took me and my family on an insane tour of it, it's workings, holding areas and even let my daughters hold a baby penguin and feed the 20k aquarium and all the surrounding aquariums across the catwalk, such a cool guy man, I was really grateful, wife said I was like a kid at Christmas lol. I must have taken 200 pictures and it was really something to behold.

I'm down for an hour long MelevsReef video about a 20k gallon reef tank, I like the longer videos. Thanks for making videos btw!

Melev, i just want to say thank you for making these videos! Your videos are both entertaining and immensely helpful!

I just wanted to say, everyone of your videos are 10 out of 10. I hate waiting on videos, but when it comes to your channel I know it is always worth the wait. I just wanted to say thank you so much for working so hard on making these videos so great. I couldn't give a price of how amazing your info, point of view, and opinions are, giving us your wealth of knowledge. Thank you so much for all you do!

it would be great to see a long video. can finally eat a meal and watch something worth my while

Thanks for the video, informative and well filmed as always. I run my carbon in my MR1 placed at the top above my GFO. Works really well to polish the water. You mentioned cyano, I ran into that problem while carbon doisng trying to get rid of algae issues. As soon as I stopped carbon dosing it went away within 2 days. I tried multiple carbon sources and they all produced cyano. I mention this knowing you carbon dose, so maybe that may be the contributing cause. Love your videos and definitely enjoy the longer videos you produce, so an hour long video, especially on such a large system, will be great to watch. I find when reviewing tank systems, shorter videos tend to rush the info and overview so not all the information can be delivered.

Hey Marc good to see you making some new videos! I personally look forward to seeing your interview with Joe, the longer the better! working as a professional aquarist myself its always nice to see how other run large systems and I know hos is one of the best out there currently. thanks again

I can hardly wait for the video of the 20,000 gallon reef, looks very interesting and sounds to be helpful. Always enjoy all your videos, it's my entertainment and also I'm new to the reef aquarium. Thank you so much.

Great video, Marc. There's a lot of misinformation regarding carbon out there, nice to see you dispel some myths. Also, good to see quality valves in your sump. Every time I see a tank with those awful white-with-red-handle valves, I feel bad for the owner -- because a few months down the road those valves are going to lock up tight...

I can watch all your video all day at work haha, Great advice and it satisfies me knowing that I actually figured out some things you talk about in your video before seeing them :) Thanks for all the important info, there is so much misleading info on KZfaq right now. Only had my reef running for about a year, and I can say your videos have helped a lot in never having a crash of any kind, I started from literally 0 knowledge on reef keeping!

totally looking forward to the long video. it'll be like movie night for the reefer in me.

A one hour video would be great! Can't wait to see it! :)

Excited about upcoming video. Will definitely watch a full hour.

I also vote for the hour long video. And thanks for this useful info about carbon, I'm still a newbie to the hobby.

Can't wait for the long video! Great info on the carbon!

a 1 hour video is good every once in a while. I'm excited to see this vid. The regular videos you should keep 20 mins or less. Most of us follow several people on you tube and don't have the time to watch long vids.

Wonderful video. Can't wait to see the next one your talking about. Thank you for all your hard work, very appreciated!! :)

great advice on carbon I used to run passively but now do the exact same as you run it for 4 to 5 days then leave it for a month I'd like an hour vid of a system like that thanks for your time and help

Wait let me run to restock on popcorn and soda! years back I read about Joe Yaiullo and I was amazed! can't wait. please make it 3 hours if you can!

I prefer the full video, but I'll watch the whole thing either way. Great videos!!!

I stopped using granulated carbon on a continuous basis a while back. I noticed I would sometimes have STN episodes after changing it out. The higher the grade of carbon, the more likely I would get some STN. Now I use powdered carbon in my diatom filter. I run it for a few hours every other week or so. It works great, I save money and no STN.

Just got around to watching this! Great video! Love the preview of what is to come!

Thanks for the video Marc! Very informative. Looking forward to the new video, absolutely love that reef!

I don't mind seeing a 1 hour video as long as see a tour of the life support system!

shoot this definetly helped me out I'm in the process of buying a reactor for carbon and we'll information out there is crazy glad you broke it down definetly my favorite channel to watch bring that 1 hour video on gives me a reason to stay in

True that. Carbon is bye bye after a couple of days through active circulation. Many are told to keep it in for a month. My return pump is 800 gallons an hour. For 1/2 cup of carbon this becomes quickly utilized and exhausted.

Thank you for all the great videos you produce. Your reef tank is amazing. "Happy reefing"

Thanks great info. I am struggling to keep my 300G tank healthy. All except my softies they are all doing well

Look forward to see 1 hour update that tank looks like the Redsea.

Nice update... The long addition of course!

Great info! Looking forward to the next videos.

Awesome Video as always. Hell yeah 1 hour video, that would be great,

The Long Island Aquarium at Riverhead! Show the full hour in one shot; that reef tank is probably the best public aquarium reef in the country.

I would keep it at an hour. That way, if someone has seen the video and there are lets say 2 points of interest to them, if someone wants to revisit the information, they only have one video to find (albeit long). You can always save it to a play list and relaunch it at the time marker that you left off on.

Very useful thanks. I do run carbon in my filter tray in a bag/sock and it works well though.

Thank you for making very informative videos melev! I'm a "virgin" to the reef hobby, but you create understandable videos to new aquarists

id love a hr long vid man !!! all ur vids inspire a inform me so what ever u post il watch lol

Very interesting video. your tank looks really nice. look forward to seeing the video on the Huge reef.

I just missed you I think last month you came down to San Diego some of my friends from sdreefs where there. I'm bummed that I didn't attend that meeting that you where speaking at. Next time for sure MACNA San Diego if you go I'm sure you will. loving your videos and reef tank. Definitely interested in seeing that huge reef make it as long as possible video!

If I might offer up a suggestion.I am super interested in the whole video, but would prefer it in smaller chunks. 15mins is a good duration. Long enough to be dense with material and allow my brain to let it sink in. You then have content for four weeks where you can release the videos in a series.

i would break that 1 hour video into 2 parts. Just for loading purposes. i usually watch your videos when I'm out with my phone so sometimes it takes a while to load. Great videos keep it up.

another great video as like you have described I have activated carbon in a mesh bag just sitting in my sump next to my return pump I have 5 bags of it for a 120 litre 26 gallon tank is this to much. and second I will get a reactor for carbon for the future. Peter from London england

Please, give us a full-length video!! I'd love to see and learn from that!!

Definately look forward to the long format videos, as long as it is full of content.. So, sure, I look forward to it... And even though I have been in the hobby well over 20 years, I find all of your videos entertaining and informative... Keep up the great work!!!

I would watch a week long video if it was about reefing lol. I can not wait to see it!!!

You should do a video on algae scrubbers and a proper way to set them up. Since they are fairly new to the hobby I believe a lot of new hobbyists aren't aware that something like this exists and I haven't found a video that goes in depth with information on why we should use them.

Can't wait for the video! I will take the long version please.

take ur time making ur videos they always come out great ...love ur reef..

Any suggestions on a video editor? Never used one or have one. Was originally just shooting the video to have as a record for myself to look back on but then thought others might benefit from my errors or triumphs. Never thought it would ever be any sort of production as I don't really have the time to do it. Thanks for feedback.

Looking forward to your next video

Stoked for new video. Where is it?! Thanks!

Awesome video as usual.

Make it as long as you like :) can't wait

1 hr would be great. I'd put it up on the big screen and watch it with the family.

1 hour is great! 2 hours even better :D

Great video! I just started using a reactor for carbon again. Before it was just a bag. Quick question, would you recommend running it for 3-5 days and not again for a few weeks, or once a week? Would running it once a week with fresh carbon be beneficial or is once a month for a week good enough? thanks!

That reactor is nice Love the color! Been using the brs dual reactors for a while now. Nice video

Hi Mel, I enjoyed the video as always. I use carbon in a couple of canister filters, simply to free up space in my sump and as you said, it works perfectly. However, I change it once a month when I do a 50 gallon water change. I noticed that you believe carbon stops working after a few days, but surely this depends on the load it is absorbing does it not? I also checked a couple of the other people I subscribe to (BRS and Mr Saltwater tank) and they seem to advocate about 4 weeks as well. So I guess my question is, why do you believe carbon only lasts a few days? I hope you include plenty of video on the behind the scenes of this large system you are going to feature. Do it whichever way i easier for you. I can either click on a new video link or pause a longer video. No biggie either way. Thanks for the videos. I find them informative and fun.

I'm cool with the long video, but maybe you could put an index in the description? That way if I want I don't have to sit through the whole things again if I want to refer back to certain part of it. Thanks

Great vid. Very informative. Love the one on the pellets too. Really helps explain everything clearly. I am starting my 270 gallon, have some very average videos but really wanted a video diary of this start up. Totally agree with starphire too, huge difference. Love to see a comment from you on my for any thoughts you may have. Thanks for making these videos, really helps and they are awesome. Would love to see one on the Calc reactor too.

Looking forward to that video

I put mine in a nylon filter sock. The trick is to put the carbon in a separate filter bag and make sure you tighten the bag so the carbon is not loose. Then the carbon is tight and has no wiggle room to get pulverized. Works great.

Can't wait for the video...

Thank you for the work you do!

Excellent. Love the vids, love the presentation, really looking forward to the big presentation on the large reef and I am absolutely tuning in on the NYOS 300. I have a 400Gal or 1500L because I am in Australia :) and I am absolutely considering the NYOS 300. It's sitting at roughly $1,300 USD which is about $1,800 AUD so I would be keen to hear if you would consider the skimmer value at the $1,300 USD price point!

Why do people have fish in their sump? I hear a lot of people say this, but have never had an explanation. I hope you don't mind the dumb question! Great channel btw :)

Thanks for your video great advice!

full video please.

well put.........great video explained perfectly

Excellent video

that clam at around 10:00 is huge.

thumbs up amazing video :)

Awesome video man

looks great cant wait

Nothing wrong with using ro/di canisters as a reactor. What do you think the “di” filter is? It’s a reactor. This saves a lot of money on overpriced reactors. Plus it is so easy to daisy chain multiple units. I have followed you for years and appreciate your insight. I just felt like your were sales pitching against a certain online vendor.

Using different types of carbon has little to do with the product size in regards to leaving/escaping the reactor, media bag, etc. Each size has a different pore structure designed to remove different contaminants; and in turn each has various uses depending on what you're trying to accomplish.

Good quality Carbon reactor that I can buy in UK please. I'm getting a new Red Sea MAX S 650- in Feb/Mar and my existing 5ft aquarium has got an external Ehiem Pro so been using pre-washed carbon on a tie up sleeve-I can testify to carbon usage. I would like to tell you it was a good day when I found your site and totally enjoy long & shorts info vids. One minus-in UK and EU we cannot get a lot of the foods / reactors etc that you advertise - use?

I was under the impression that when running carbon in a reactor, one should push that top filter sponge and the filter plate down onto the carbon in the reactor so that it cannot tumble to reduce the amount of carbon tumbling and dust created? Or perhaps your low flow handles that. Thoughts?

Top guy 😀👍🏴󠁧󠁢󠁷󠁬󠁳󠁿

I've been in the hobby since 97' and embarrassed to say that I did not have a good understanding of the use of carbon. I have always been aware of how it polishes the water, but always thought it did much more in terms of removing organics. I don't run carbon all the time, but probably ran it a lot more than necessary. Any thoughts on the limited use of carbon and preventing lateral line disease? I look forward to the video on the Long Island aquarium, even a really long one. Thanks Mark!

Looking forward to the long video :) keep up the good work!! Also... Regarding carbon. What's your opinion on extruded carbon vs granular when running ozone? Thanks :)

LONG video please!

Long 1 hour video > short clips! :D

Thanks for the video on carbon!! My montipora started peeling off on the side when I ran the carbon for 2 days and I just realized I put too much carbon. My water came crystal clear but my montipora were not happy. Lesson learned. Should I deduct the live rock from calculating 1 cup per 50 gallon? How often and how long I I should run the carbon? I am nervous to run it now after what happen to my montipora..

Hey Melev, be sure to show us the filtration of this massive reef.

awesome video bro!!!
