Happy 5th anniversary! Beautiful natural looking reef tank. Thanks for all the amazing work and dedication you have for this hobby

Getting better and better every year. You are a valuable youtube reefer Marc, thanks for all the content. May you have luck for years to come!

Congratulations on the 5th Anniversary. I always enjoy a look at your tank and setting. Cheers!

Thanks so much for sharing your amazing reef, and letting us share your enjoyment!

I'm new to the hobby, just got a 40 gallon, I appreciate your dedication and passion !

There are too few words to describe how exceptionally beautiful your tanks are. Thank you for sharing.

Happy reefing, always enjoy watching your reef and all the beauty it beholds.

I love the fishes reaction to feeding time!! It’s not like they could smell it but they anyway all swam to you. Wow!

Love your video's Marc. Thanks for sharing them, they are helpful and entertaining. My own tank is just turning 4 years old. It's not as big or well appointed as yours is but I get a lot of pleasure from it. Again, thanks for sharing.

I really enjoyed this update.. Everyone was setup so well and easy to maintain that it just runs itself!

Looks good you are giving us a good view of your 400 reef. Congratulations on 5 years.

Happy anniversary! Love your tank mate. Keep up the good work.

Really glad I stayed for the end of the video, beautiful view when you put the camera inside to look around

Congratulations on your amazing tank. Thank you for sharing, I watch all your videos.

Congratulations Marc !!!! It's great to see a reef older then a year or two ...Can't wait for the 10 year anniversary ( YEAAAHHH ) !!!!! Marc i really appreciate your channel and all the good information that you share with fellow dedicated (Obsessed ) hobbyists..... THANK YOU Marc for sharing !!!!!

VEry nice mark. I never realized the number of fish until feeding time!

Congratulations Marc, on five years of keeping a lovely looking reef. Keep up the great job that you are doing :)

Beautiful Marc. Happy Anniversary 🌹

Happy 5th year anniversary wow Melev time flies....awesome update i enjoyed every bit of it...

Happy Anniversary, Tank! ;-)

Congrats on the five years! I do not keep aquariums, but I really do enjoy learning about reefs. Great video as always, looking forward to the content that was cut :-)

Wow Marc the reef is looking really awesome. Love the under water shots.

You do alot for the reef community, thank you so very much.💜👌

Beautiful setup! Happy 5 year anniversary!

Just hit my 1 year anniversary for my reef! I Love your reef man!

Absolutely phenomenal all-round! And that floater box.. almost as brilliant as the walk board.

Happy anniversary. I love these updates.

Dude I think this is my favourite video ever from you. It is definitely the best shirt I have seen you in. It fits you perfectly and you look super trim in it - you should buy 10 of them. I love the tank and the no filter look at the start. Lot's of great tips too especially at the end - perfect ;)

You can tell your heart and soul is in the tank. Super AMAZING!!

Nice video. Thanks for including us in the 5 years celebration.

Congrats on the 5 year anniversary. I remember what you went through with that tank in the beginning. I miss that monster leather coral you had.

Gorgeous my friend!!! Absolutely paradise

Wow! So beautiful! Congrats

I love your reef! I can't wait till I get a bigger tank. I have a 24 gallon all in one tank with a few corals. And a couple fish.

Wow, beautiful inspiration! Thank You.

Fastest 23 minutes I've experienced on youtube. Thanks for the breakdown Marc, excellent vid!

Beautiful reef Mark. Happy 5th

Incredible. Great job. So inspiring!

title should be "The Great Melevs Reef". Congrats on reaching 5 years! ...keep doing what you do !

Happy 5th Anniversary!!!

Awsome update bud, congratulations!

Amazing system pal, most impressive and stunning

I love your channel, your videos help me a lot with my reeftank.

Happy 5th anniversary 👍🍾🥂

Tank looks beautiful 👍👍

Happy 5th anniversary ✌️🙌🙌👍

I LOVE the open top!!!! Such a beautiful and well constructed tank.

Those thumb downs must be freshwater enthusiasts.. Great tanks! I like your electronic island stand I thought I was the only one to do that lol😅

Spock loves you. Happy aniversary!

Looks better without filter!

Your reef is amazing the best one I have ever seen great job and love the video,s

Happy Anniversary!

Stunning, simply stunning.

Wow that’s a dream tank!

Beautiful tank , wow so many worms in that sump, must be hard to clean without sucking them all out!

New sub here.. Sir I must say this is maybe my 3rd or 4th video I've seen from your channel and all I can say at this point is that I'm beyond blown away.. I kept freshwater aquariums from the age of 10 till right around 30 years old when I decided to take a break when we moved to an apartment so my daughter could attend a specific school district and well I'm 40 now so that break went much longer than I planned lol. Anyway I was recently given a 20 gallon tank with just about everything id need to start freshwater but have caught this crazy bug called saltwater or marine aquarium hobby so have yet to decide what to do with the 20 gallon. Working with a very low budget so will probably be some time yet before I can act on any decisions but I would absolutely love to attempt keeping a reef or coral aquarium. After watching this particular video I've realized just how much I don't know about marine biology whatsoever, sadly. But as with all things we can learn, eventually lol. Curious tho about what you might estimate your setups would or about what you think you have spent so far? At first I thought easily over 20 thousand but after this video I think I'm probably off by 70-80 thousand? Anyway sorry for the long comment but again I'm blown away by the complexity of your system and feel like I need to take a few classes before even thinking about starting my voyage. I'll definitely be tuning in for your next uploads. #Amazing!!

Beautiful. Great video

Whew,I'm glad I broke the reef habit.. I can just admire a great tank like that now. How do you resist the "Just one more fish" syndrome.-ha. I still have that with my 240G freshwater Rainbow-tetra tank. Hard to stop.

This is a fantastic tank tour, thank you for walking us through your system! That side view of the 400g tank from the Anemone tank is breathtaking. And holy smokes, that sump is a mad scientist's lab... I already have a phobia towards having to talk someone through trouble shooting my simple system when I am not home; I cannot imagine what sort of instruction you would have to give in order to remotely debug an issue. o__O

Beautiful tank

Awesome tank!

Congrats I wish I had a salt water tank all the fish you can get are amazing

You're playing with fire there with the open top, Marc. Congrats on 5 years

Looks great, glad I'm not the only one with bubble algae 😂

looks great you make it look easy

Congrats! I just went to the Long Island Aquarium and met Joe. He took me to the back and I got to feed the fish at the 20k gallon reef display. It was awesome! I’m pretty sure he has or will send you a picture.

Congrats the reef looks great

Spectacular Reef!!

Great Job, Congrats!!!

Living the dream keep it up !

Magnificent tank and setup... absolutely stunning.

Very, very nice vídeo! The 6 aniversary? Doesn't was ready? I wait for it!.....

Congrats on your 5years! That's awesome and definitely is a sight to see. Good luck on your next 5 years lol

One word again BEAUTIFUL👍

Great video!

Love the tank, had my wife and I captivated the entire video. Keep up the great work!

omg the top view is amazing Marc

Happy Anniversary!!

That walk board was a great idea

Super nice tanks

happy Anniversary

Amazing!

Love this tank.

congrats!

You have an amazing reef!

This is literally the coolest thing ever

Funny my lfs still have vho’s congratulations mark , bountiful tank.

It looks really good Marc, congratulations!

Fantastic.

bottle of Skol vodka chilling behind the anemone cube lol

Love this tank - can’t believe you’re running an abyzz pump and instead of a chiller you have a computer fan haha If my tank looks anything like this after 5 years I’ll be a happy man!

I love fish, I want a big fish tank like yours but I know I wouldn’t be responsible enough to keep it clean. Nor do I have the space or money. So you have a new fan because I love your fishies! (This sounds like a child wrote it so even if it’s weird to say, I’m 16... it’s just 2 in the morning)

Amazing...

wow all that passion! 😁😁😁

That’s old School what a glorious mess under your tank,,,,

Congrats on 5 years Marc! I feel like I just watched your 4 year video and how you were upset that it was so empty compared to your 3 year video. At 14:59, I see you still haven't figured out how to make your gorgonian stand up. haha Is that because Joe wasn't comfortable giving you advice on how to make it stand up? All jokes aside you have a beautiful reef tank. Keep the videos coming!
