Hi All,
Looking for some advice. I switched my tank to a sponge filter from a canister. It is a soil with sand cap; planted 75 gallon. Sofar I love the quieter noise, and far easier operation. I have great flow with the easy flow adaptor 1/2 showing at the surface.
Tank parameters: stable at 20-25 Nitrates, PH 6.8-7, mid range for GH and KH. No Ammonium or chlorine.
My challenge has been the sponge only seems to be using the top 5-10% of the filter. I connected my airline to the handy port. My water doesn’t seem to clear up from the sponge. I put in a small oase skimmer and hair tied a piece of white sponge to it to test- this seems to clean the water overnight (and gets very dirty). So my thought is that the air isn’t creating enough draw to use both sponges.
I am wondering if I should place the air line with air stone and place it further down in the lower sponge.
Anyone else have experience with this?
Pictures of the tank(sorry low res, hi res was giving me problems), and a closeup of the top of the filter and my test skimmer setup(freshly cleaned)
Thank you in advance!
