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. 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!

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.

This filter is awesome. It works better than any filter I have ever had. I have. 75 gallon tank and I have plecos in it. I feed them green beans so my water was always cloudy no matter wat I did. I put this filter in my tank and 15 mins later my water was clear.

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.
