hey,quick question here.75 gal tank,bare bottom and i have 2 hydor lVs sponge filters for the tank. Ialso have a rena canister but it seems like more work than just wringing out the sponges.MY question is are the 2 sponges too much and if not should i run them both off air, or one air, one powerhead?probly be stocked with 6 fish.Oh and i plan to change 40%water every day or is every other day sufficient?
