So I’m thinking to do a sump tank offset to my 20 gal established tank I think if I put a black cover in the tank for pump and heater have it go into sump into refuge with the drilled hole in 10 gal tank over flow back through pipe into display? If that makes any sense I do t want to do u tube siphon last thing I need is to have the siphon break and come home to the mess and I don’t want to drill into my tank with water being I never done it before and maybe if I can make it pretty cool looking I won’t mind it in the living room
