we have 3 filters. 2 bio-filters (penguin 125) and a H.O.T. canister filter (hang on tank;magnum). we've got 2 bubble walls that helps with the circulation of the water. this hour the hydrometer is reading at a .019, which is a little under where we need it to be. we also dont have our heater hooked up yet. i read somewhere that the temp of the water does mess with the hydrometer a little.
