Outstanding once again! Please try to share your videos everywhere...they are truly unique and one of a kind...no one explains aquariums, filtration, etc as we as you do...

Cory from Aquarium co-op need to share this series! Awesome information. Can't belive you dont have ???k of subs. your did a awesome job on this ! , thanks so much!

Thank you Jay! Most precise and informative video I've found after searching youtube for days

Thank you so much for your time and energy. Simple explanations help me to understand some filters that I knew about but did not understand how and why they worked. Now it is crystal clear. I love your style. The sound of your gentle voice and the sound the marker besides the brilliance of having drawn illustrations all ready to go. All round a brilliant display. Please do some live streams. That would be great!!

Thanks Jay, great series of videos!!

Jay thanks, I'm new at this and your Basics 1-3 was so enlighting. Now I can set up my filtration system with confidence that it will be done right.

Hey I learned something 👍 good videos

Wow ! I came by after searching for moving bed filter ! Nice and simple video but lot of information in it ! Thanks !!

Excellent Explanation. Very detailed and easy to understand....!

Thanks for the detailed information. Great vid.

Nice real-world description. I am interested in how each type performs with short power-outages.

Awesome video, perfect explanation. Greetings from Brazil.

oxygen is the limiting factor! thanks for sharing 👍

Thanks for explanation in simple terms keep going

Your explanation videos are superb, thanks so much!

FYI: "Anoxic" refers to an environment that lacks oxygen whereas "anaerobic" refers to an organism or process that doesn't require oxygen.

AWESOME,AWESOME VIDEO THANK YOU SOOOOO MUCH FOR SHARING IT

Great Video, Thank you very much Jay.

Awesome video very informative 👍

Really great video.

Great Video, thanks for the explanation, very helpful and well done.

Thank you.

Jay wet dry is not limited and neither is fluidized... simple adjustment of baffles fixes all issues. I run a submerged 55g sump that has two fluidized chambers as well as a low flow chamber for nitrate consumption. By simply using different baffle heights you can use any type of filtering at any time wo sacrifice. The only downfall of wet/dry (and the reason I don’t use it on my sump) is you lose a lot of water capacity due to all the air. My intake comes down to a fluidized bioball chamber. (Intake is low in chamber and baffle high) I like bioballs for capturing detritus not for filtering. The water then spills over to a bubble baffle high then low setup. From there I run k1 media with 1 air stone 6” Long. The water then spills over another bubble wall baffle setup where I have biomedia. This area is 17” lone but split in half with an almost full height baffle. The second half runs my nitrate chamber. Because it’s one chamber with bottom intake under baffle and overflow baffle on the other side.. by having a split wall in the middle I get tons of bypass which results in low flow for the nitrate chamber. From there I run yet another bubble wall baffle setup to my return pump. Point I’m getting to is with proper planning you could run all three types of filtering in any given setup at the same time. I would actually prefer to do a trickle over my bioballs and remove my k1 and replace with Something else... but I won’t give up the 15 gallons or so of water I’d lose. Ideally I’d run trickle over balls, followed by smaller k1 chamber, followed by some quality media then a big cheato chamber. I could very well do this now by simply moving a couple baffles. That would give me submerged, trickle and fluidized all in the same system. Everyone says you have to pick a system and go with it.. that’s BS. By simply picking proper baffle heights for each chamber you can do anything you want.

Amazing info mate

Also: O2 has low solubility in water, because it is a nonpolar molecule in a polar solvent.

Awesome information, subscribed!

Outsanding ! Thanks Jay, your videos have the most clear explanation I have seen so far on KZfaq. Just one request though...please switch to another kind of pen that does not make that screechy sound when you write....gives the very unpleasant feeling of fingernails scratching a wall 😖

Thank you for sharing this information!

You are a natural teacher Jay, do you teach the sciences for a living?

Its very useful, thank you very much👌🙏

Thanks for the interesting video. I'm considering using a moving bed filter. Or a wet dry filter. But I heard that a dry wet filter causes the co2 to escape from the water. And that's why you can't use this filter in a plant aquarium. Is that true? And is this also true for a moving bed filter. Can an artificial supplement compensate for the loss?

Whoop loving these!! 🦐

hello jay may i ask what is the best media for fluidized/moving bed filters ? k1 micro k1 or bio ball ... ?

I run 2 liter bottles of k1 media X 2 with some bio home in the bottom just to weight the bottles down. My canister filter has only filter pads as I fully trust in the k1 and don't need extra media in it. I've tried every media from bihome, marine pure, ceramic rings, plastic bioballs. K1 IS THE BEST

Jay thanks for this videos they are helpfull, i have a doub about the kind of filtration media wich is Better for a Wet Dry filter do you have some information about it? Saludos from Mexico

Fluidised material like K1 offer very little surface area when comparing With wet dry filtering material. Therefore it will not have sufficient room for bacterial to live

With fluidized sand filters however you seal the container like a canister and pump water in to generate motion. Where is all the air gonna come from if the intake pump is submerged? It becomes a fluidized submerged filter then and not sure if it's any more efficient.

Great series. How much k1 will I need for 375 gallons?

How does a fully sealed and therefore submerged media moving-bed filter have any more O2 than a canister filter assuming the same level of O2 in the aquarium water? You're not pumping any air into that moving bed so how can it have more O2? I can see the point in large water treatment facilities where the moving bed is open to the air and it gets loads of air pumped through it ie, it's not in a sealed container but any moving bed filter I've seen for aquariums are sealed chambers therefore, they will have the same issue as canisters as regards O2 levels. A fluidised bed filter reactor chamber is just a canister filter with media that's small enough to be mobile under water flow. It has an advantage in self cleaning it's surface, but no advantage regarding O2 levels in the water. To get the bonus O2 advantage, the fludised bed would need to be open to the atmosphere and have air pumped through it with the water. That's probably only suitable if you have a sump.

What exactly, in this context, are you calling efficiency. Does electricity consumption come into it?

Exelent explanation...one question...if i run a sump with ceramic rings in one compartment and want to set another compartment with fluidized media...then.. is it convenient to set first que lower oxigenated filter process like submerged ceramic rings (ir something similar) and have a somewhat anoxic filtration and in second place the fluidized so that more oxigenated water goes back to the main tank...or the other way arround or am i understanding the process wrong...please advise ...thanks

If submerged is low efficient, then why external canister is being commercialized that much?

Nice explanation Jay. Small clarification , Currently I am designing a filter ( out door) for my indoor Aquarium ( 6' x 2' x 2') . i am planning to use all 3 categories of filters for this , Submerged , tickle & fluidized filters for this. What will be the preferred, sequence for this ? Pls advise,

Jay great explanation i want to use you'r video with my student but i have to translate it so they can understand it. can you give me permission to write subtitle in Hebrew or to make a copy of it translated to Hebrew?

Very nice information here however may I suggest using a marker that does not produce cringing sound?

Marineland filters although they are submerged the bio wheels increase the oxygen efficiency correct?

low oxygen is needed to convert nitrates you need all three types of filtration to complete the cycle

gréât video

I am disappointed that I have a over sump dfilter

How much k 1 per 100 litres please

how to do anaerobic filtratoin?

Thanks Jay for your vids. I remember another youtuber, which is using a lot fluidized, who said that fluidized is very efficient because the media as is acting as a carbon source for the bacteria. He also mentioned that it is consumed quite rapidly. As sand can be used as fluidized media, I imagine it is less efficient or need a carbon source to be efficient. Do you have any idea about it ?

I'm honestly kinda lost. I currently have a submerged sump filter. I have turtles and my current sump cannot keep up with them. So I am wondering if a fluidized filter was better? cause my turtles produce a lot of waste and even with weekly water changes of 50% the water still is not clear and needs fully replaced once every 2 months.

At 3:06 you put the lone pair of elections on the nitrite N, but then left the nitrate N hanging. Lol.

does the fluidized filter effectively trap solids?

Hi Jay, I have been reading that fluidised beds can also reduce nitrates. Since this is a high flow filter, does this make sense?

Trickles only matters if you have large fish in large tanks. Yeah right. Are you making this up as you go.

same space, wet dry best.
