I have a 55 gal tank, and started with a hang on pump system and now have 2 on the tank (one at each end)both for 45-60 gal tanks, I also have the tray part for a undergravel system, and have read contradictory info on these. Should I get the tubing and pump to activate this or not? I'm still in the middle of my cycling process, i was given an abundance of guppys.
Thank you to any advice
