I am cycling a 55g planted. The nitrites have been off the charts for about a week now. I still have some ammonia since the first dosing which is weird, but it has lowered. Nitrates are pretty high as well, ~80. I thought I'd speed it up by seeding from my other tank. However the other tank has a HOB filter with cartridge and this is a canister. Is there a possible way I can seed the canister?
