Amazingly high quality at remarkably inexpensive cost!
These are fantastic, and such a bargain! I got nearly half a year’s worth of filters, both types that my Aqueon system uses, and in the perfect sizes, and the price for these is less than half of what I normally spend in 2 months on brand name filters! It’s like buy 4 get 8 free, plus the little ammonia-catching sponges as a bonus! I have been using them for 2 weeks now, and am so pleasantly impressed! I now have a new resource for my aquarium needs! My fish are quite happy, and that makes me even happier.These are high quality filters, very effective at maintaining the cleanliness and health of my tank. I’ve bought some off-brands that were almost worse than nothing at all, but these filters are at the complete opposite of that spectrum!! Usually, by the second week of a filters use, I can start to notice little things starting to get ahead of the system, despite a double filtration system of that required for a 70 gallon tank. But not with these filters; the water is still completely clear, and there’s no greenage growing anywhere yet. My pleco is actually getting pleco-tab supplements because there doesn’t seem to be enough else for his appetite! ( but I don’t mind! I love it that it’s staying clean so well!)I don’t mean to gush, or sound giddy; I’m just really, Really pleased to have found such a high quality filter at such a low price, and all inclusive, at that! With the price of everything so high lately, this was like finding a dollar bill in a parking lot, only to discover its really a $100bill!! (And yes, I CAN say that’s what it’s like, because I HAVE done that!)I can’t recommend this strongly enough to anyone who loves their fishies and doesn’t love the outrageous price pet stores demand for filters these days! You really really want to try these out! You won’t regret it!

Really cleans up the fish tank water fast
Iâm really impressed with these filters. Iâve had cloudy water in my tank for days now. I have 2 large goldfish that produce a lot of waste since they eat so much. I got a larger tank filter just to keep up with them but slowly the water has been getting cloudier even with doing regular water changes. When I received the filters I immediately tried one, hoping that they would help make a difference. They did not disappoint. The next day my water was so much better, cleaner, clearer. These filters definitely grab the fine particles and clear the water quickly. They are durable and collect a lot of waste and keep hold of it. They donât disintegrate or fall apart easily and didnât make a mess of the water when I pulled it out of the filter house to change it. They work great and Iâve been changing them out every 2 weeks, when before I was changing out my old filters every few days due to them not keeping up with the waste. Definitely recommend these filters. Iâm happy. My fish are happy.*the first pic is how the water looked before and the second pic is how it looked just after one day of using the filter. **the floating particles are food that I just fed them.**

Good filters
I got these filters for my Zilla water filter and they fit exactly as expected. The 12 pack of medium cartridges gives me plenty of replacements to last for a while, and I like that the design matches the fit of the original Zilla size 20 cartridges so there is no need to trim or adjust. The filters slide into place smoothly and the frame feels sturdy enough that they do not collapse under the water flow. I also found the 8 pack of ammonia reducer pads to be a nice addition since they tuck in with the cartridges and help improve water clarity by cutting down on ammonia build up. After running them for a couple of weeks, the water has stayed noticeably cleaner and clearer, and the fish look healthy and active.What I appreciate most is that the filter pads actually make a difference in maintenance since I do not have to change the water as often and the tank does not develop that cloudy look as quickly. Each cartridge seems to last about the same amount of time as the branded ones I used before, which makes this bundle feel like a good value without sacrificing performance. I also like that the filter does not slow down the water flow, so the current in the tank stays steady and the biological balance feels stable. For me this set has been a reliable replacement that keeps my tank running smoothly, and I will definitely keep using them for regular upkeep.
