So far I’m really impressed with the way the filter works, seems to be keeping the media clean, nitrate are already lower (20ppm)
Purchased an initial unit to try it out and it was extremely efficient in reducing my nitrites in my 55 gallon tank. Upon those results, I purchased two additional units which have made all the difference in stabilizing my other aquariums. I think they are an effective and inexpensive way to maintain your aquarium water quality without an expensive equipment upgrade. Worth every penny.
Took about two days to fully fluidize but it is working like a champ! Put it in my 20 gallon long just tilted to the side a little and it works great as a filter and something to add interest/water movement. Still testing its bio capacity but I have high hopes once it gets properly colonized with bacteria. If you enjoy the microbiology of aquariums you will love this filter
Seems to be an excellent filter! Easy set up and began to work well within the first 24 hours. I'm glad I bought two of them!
It took a few days before the media would swirl around. It does make a noticeable bubbling sound, so keep that in mind if like a quiet aquarium. Not sure if it adds anymore benefit apart from a sponge filter, but it’s different and cool to look at.
