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)

High quality product for the cheap price.well recommended specially the seller🤙🏻🤙🏻🤙🏻

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

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. 🙄

I had 2 filters in my 30g tank, a fluval U3 fluval and tetra whisper 40i, i like the tetra whisper but i had enough with the U3, was complicated to clean and the flow was too powerful for my kind of community tank, so i bought this one (the AQQA large) to replace it and i am very please: in less than 48hres, it removed the biofilm flotting on the water and my water is cristal clear, and my fishes love it. Remarks: 1- the bubble sound is noticeable, but too me, not unpleasant but if you cannot tolerate noise or if the tank is in your bedroom, it's something to consider. For me, the air pump sound is more bottering than the bubble sound. 2- you will need tubing and an air pump. The packaging of the filter suggests a 5 watts pump to allow all the beads to move in the filter. If you take a 2w or 2.5w, it will not be enough for the large filter size. I tried at first with a 2.5w but it was not enough, half of the beads were not moving. I went with a 4w and it's perfect. 3- i did keep my tetra whisper filter along the new AQQA one. I don't know if the AQQA alone would be enough to keep the water clean. Overall i would recommend.

Ordered two of these for an over stocked 70g to replace a pair of sponge filters and accompanying two Fluval 407s, both set up as straight biological. Due to the fact I’m over stocked, heavy filtration, namely biological is necessary. I use no chemicals and haven’t for the 15 years these guys have been with me. One thing I need to say, I’ve seen the review videos on here where people aren’t using a big enough air pump. That K1 media needs to be tumbling, I mean, it is by design after all. Also, I replaced the fine foam that it came with plastic pot scrubbers which excels at growing bacteria. If you don’t have them, just take the foam at the bottom that it comes with out. That foam is too tight and acts as a mechanical filter which will require cleaning. DO NOT CLEAN THIS FILTER. Use it as a Biofilter. It will take about 4 weeks to establish, but make sure you have plenty of flow through it so it’ll be effective. The purpose of the this filter media is not to filter out particles from the water as is often assumed. The media serves as the habitat for a vast array of microorganisms that include bacteria, archaea, worms, ciliates, flagellates, and many others. These microorganisms live in a community that is based on biofilms. The biofilms are created by bacteria that secrete extracellular polymeric substance (EPS), which is often called “slime”. The community forms a bioreactor that processes the waste and turns it into food and energy for its members, and ultimately into organic or inorganic products that are then used by plants, evaporate, or removed by water changes. It takes a considerable amount of time to establish this “filter community”; consequently, it is very important not to disturb it unless absolutely necessary.

I like this product, quiet, works great, good value, easy to clean, easy to assemble, durable

I’ve had two for about 3 years now. They’re great! My only issue is I can’t find any replacement parts. The suction cups have split, the air stone clogged up. I like them but can’t keep them stuck to the tank.

Great value for an aquarium filter. Started reducing nitrates within 3 days. Short break-in period. Simple and effective.
