These can be used to add filtration to most filters. Just check out the video below on how to optimize your filter. Of course you can use them in your aqua clear filters but also other filters and you can cut to fit them as needed.
Great for filtration, especially if you have cloudy water from substrate or food debris.
I cut a square of this to use as a baffle at my filter output and it's worked well.
I like the texture; lots of surface area for good bacteria.
works so well - forgot to wash my substrate so it was a horrible cloudy mess - this cleared it up so fast!
I have 5 tanks and used these to hot rod my hob filters. I love that I have more surface area for the bacteria and that these don't have to be replaced every month.
Delivery was quick and accurate.
I bought 3 for my 20 gallon and am enjoying it. Water stays clear, and notice no bad issues.
I only keep carbon filters for when I need to use my quarantine tank for a sick fish, but in my main tank these and the sponge filters for the opening are all I use. - will buy more in near future for my other tanks
The sponge was exactly what I needed to hot rod my hang on the back filter. The delivery was quick and the customer service was excellent!
