I have a 150g front tank. i have 7 3" fronts and 7 tangs all about 1" each. i also have 4 3" clown loaches. i have a cascade 1500 canister filter rated at 350gph. it says tanks up to 200g. i also have 2- 75g biowheels rated at 350 each. the canister filter seems to have alot of bypass and does not do well. what would ya'll recommend i should do to for better filtration? i know sumps and W/D filters are best but i'd rather not go that route. please any suggestions. does anyone have experience with the cascade 1500?
