SunniSki Posted April 12, 2022 Share Posted April 12, 2022 Let me start of by giving you a bit of a background on what is going on in my tank. A few months ago I believe I introduced parasites and Ich in my tank with some new fish. Meanwhile I had "pest" snails overrunning my tank which rode in on plants. So in between 2 months of treating the parasites and then a fungal infection... with Ich-X, Maracyn and Paracleanse... and over cleaning my tank weekly and still seeing pest snails.... I made a grave decision due to my canister being overrun with Pest Snails.... I DUMPED All of my filter media in the canister filter. I did have a sponge filter already in the tank which should have been well seeded and I also pulled the Matrix out of my canister filter and dropped it in a fine mesh bag (hoping pest snails wont escape) and put that in my tank. I was thinking... yes it may throw things off slightly but I have a well established tank and a per-existing sponge filter running in my tank, things will balance super quickly. BOY... was I wrong. Rookie Mistake but I was so sick of the pest snails and they made a motel out of my canister filter, I made a rash decision out of frustration. So let me get to the question... Does the coarseness of the filter sponge matter... I ask this because I purchased one from Top Fin before ever discovering the Aquarium Co Op site.... I have the large Top Fin sponge filter and I now see its not supporting my bio-load which I thought it would be able to. Can it all be due to the coarseness of the sponge media and not having good water flow???
