Bought a 65 gallon tank that was running for a year, but the owner got a bigger one and gave me this with everything included, but lights and stand. I build my own stand replaced the piping because it needed a touch up. I filled it with freshwater everything runs smoothly. I’m putting in the 36-48 IC Loop Pro Dual LED Marine Complete System for lighting. I know I need an ATO and I believe I am ready to cycle the tank. Any advice would be appreciated.
