i just bought a 150G tank 60x19x30. the tank has 3 bottom drilled holes in the middle of the bottom glass, 2 on the left and 1 on the right. my question is: " what is my filtration system i can setup?" i already have 2 canister filters in hand from the old tank. i really want to use the sump but i don't want to drill anymore hole on the tank. im planing to keep South American Cichlids maybe Arowana.
