AQQA Aquarium Fluidized Moving Bed Filter,Media Submersible Sponge Filter with Air Stone Ultra-Silence Dissolved Oxygen,Air Pump Accessories,for Fresh Water and Salt-Water (L 15-55 Gallon)

The media could not be loaded. I have a 75-gallon Amazon tank and have wanted to boost its bio filter for some time. I am tired of rinsing bio-sponge material out and replacing it. After researching fluidized beds, I realized they are the most hassle-free way to increase biological filtration, and really, are structurally perfect. The one problem I was facing was that for a 75-gallon tank, I was going to either spend a lot of money to buy a larger set up, or the tank was going to need multiple units in the tank.I bought two of these for under $40 total and decided to play around with them to see what could be done about combining them.Since they are slightly larger at the top than at the bottom, stacking them would not work; instead, I used my Dremmel to cut the bottom portion of one of the tops free. Then using the sanding features, I was able to remove a portion of the ridges inside the band, so that I could fit the adjusted end over the top of the other unit. It ended up being a sleeve to combine the tops. With a little underwater tape, the middle was set. I also took sponge out of the "top bottom," and in its place I put some underwater tape fashioned into a little cap with a portion of it cut out (to lead the bubbles into one spot). I cut the bottom sponge in half, too, to increase the inflow.Then with the media inside, I connected the bottom air hose attachment to a fairly strong air pump, and with some air hose, I attached the top air hose attachment to the aerator insertion point of the outflow of a surface skimmer. This way, the skimmer's powerhead pulled a current out of the top of the "top bottom." The result has been nice! The water is only a bit cloudy now because of all the aeration from another power head. The water is very clear and mature, the corydoras' barbels are long (meaning, no nitrates), and the tank just seems healthier.It's not the prettiest set up, but for the price, it is really functional (the plants hide it from the front, anyway).These fluidized filters really do the job and at half the price that I would have had to pay for one as big. I do recommend this unit, as its simplicity and appearance both are more than adequate for the price.

The media could not be loaded. I have made my own “water bottles” with small media inside and used an aerator and stone to roll media in my aquariums. Which works great. ( Looks Bad ) To see something like this with a much cleaner and more appropriate look for any aquarium I was thrilled.Now that I’ve received the product, it works great. Simple set up.Make sure you soak the media as instructed to avoid some of Stop them clumping at the top. If not you will end up unhappy.Follow directions. Hook up, set and forget! Maintaining the appropriate biological filtration for you aquarium is key! This helps tremendously to achieve just that!!

I bought this filter because I wanted to make my Saltwater, or Marine Aquarium have a better water flow. I was hopeful that the biomedia within the filter would be an added bonus. I love that this filter moves water from the bottom to the top of the tank and acts as a small wave maker for my fish. However, it doesn’t do much in the way of filtering the water. So, if that is why you’re buying it, it may not serve your purposes. Just keep that in mind before adding it to your cart. But for me, it serves the exact purpose I wanted it for.

Was skeptical about these filters but after 3 weeks I have to say I'm impressed. It has helped to stabilize nitrates in a 75 gallon that has no live plants(ciclids). Little large but was able to hide it behind some driftwood and rocks. Cleaning is simply pulling the bottom and rinsing the foam in tank water, haven't had any algae buildup or anything so far. All you need to run it is an airline so setup is super easy.

Folks, if you’re going to buy these, understand what they really are. They ARE NOT SUITABLE AS THE SOLE SOURCE OF FILTRATION! These are fluidized bed media reactors that happen to have a piece of foam in the bottom. Yes, the foam will filter water UNTIL IT CLOGS UP! What these are good for is tumbling media that do one of two things. Provide a home for bacteria, or provide a home/food source for bacteria. First thing to do is yank that foam out. Throw it away. If you want to provide a home for bacteria, use the media that comes with it. What I use them for is to tumble DrTim's Aquatics NP-Active Pearls. This product provides food and a home for beneficial bacteria. Here’s the scoop:“ NP-Active Pearls are an easy alternative to carbon dosing, suitable for all water types, fish, and corals. 100% natural polymer pearls grow beneficial bacteria & remove nitrate and phosphate from water. Naturally the carbon pearls clean messy fish tank algae. Keeps your aquarium balanced. Pearls should be placed in a fluidized reactor or similar device where pearls are kept in constant motion with sufficient water flow.”I have 6 aquariums. A 90 gallon reef tank, a 33 long saltwater for my moray eel, and a 55 gallon salt water fish only. On the freshwater side, a 55 gallon with Tiger Oscars, a 20 gallon tetra tank, and a 10 gallon planted shrimp tank. Every one of them but the 90 gallon have two things, one of these reactors with Dr. Tim’s pearls, and an algae scrubber. All the saltwater tanks have custom sumps with a custom algae scrubber built in. The freshwater tanks have HOB algae scrubbers I custom build using Marina filters.I’ve been an advanced aquarist for over 55 years, have a BS in Marine Biology and a MS in Mechanical Engineering. I can’t tell you how many cars I could have bought for the money I’ve spent over the years on stuff that just doesn’t perform, so I either design/build from scratch or design/modify OTS hardware. I never have water quality problems, and if I lose a fish, it’s due to old age.

The media could not be loaded. It's cycled in less than a week, and also it doesn't clog, which is perfect and because i am tired of taking out the sponge filter and wringing it out and making a mess everywhere.And the suction is super strong! 4 of them sticking really strong to the glass and I'm confident it will stay right there for a long timeAnd this tank is full of sensitive fishes and shrimps. These guys of 20 little cherry shrimps, celestial pearl danios, and chilli rasboras are doing amazing!

Didn’t expect it to be super big. I didn’t expect it but it works nice

The media could not be loaded. I just purchased this filter to add something more compact to my grow out tank. The quality is great and the pre-filter is much easier to clean than my other filter. I like how the bio media continuously tumbles letting the live bacteria thrive. The suction cups work great to hold the filter and there is a hole on the back for you to attach your air line. This is a nice feature which keeps the tank looking great. I would recommend this filter to someone looking for a moving bed filter.

The media could not be loaded. Il na pas d'aspiration de déchet.Très gros le petit dans une 10 galonFait des bulle, jespere que cela aidera a rebalencer mon écosystèmes car sa ramace aucune cochonnerie. Pour un bulleur, ce nest pas ce qui est adéquat!

The product itself is good, but the lid, top part of the filter comes off very easy, I have found that white media all over my aquarium many times. Lid just comes off and all media scatter all over the aquarium.I have ordered new one couple of days ago, small one.. but I have received large one. 🙄
