I'm torn people. I'm def an overfeeder because I have too much of a bioload in my 13.5 tank (working on it will upgrade eventually). Parameters are all leveled and I have a protein skimmer (PS1) but honestly I don't even know if I'm using it correctly lol sometimes I see gunk which means it's working other times it's just filling with water and bubbles. Should I get an inTank Media Basket? Should I try a different nano protein skimmer? I need tip top filtration. I also do weekly water changes (about 4 gallons).
