I am currently running a eheim pro 4+ canister filter attached a uv sterilizer to it , 2 jebao wave makers, and heater . I want to set up a sump I have bought a 20 gal one and a protein skimmer with some pond pumps not sure if I need both but got them off of marketplace so cheap for $30 how do I set this up. Also how do make sure I dont get flooded if I ever loose power ? My tank is not drilled so it will need to hang not sure how that would work any info will be greatly appreciated!
