I want to set up a drip system or something similar on my 518 gallon tank, but i don't know how to go about doing it consdering i am running overflows for my sump, i am worried that if i was just dripping water into the tank it would just flood my sump instead of going through the other overflow for the drip system???? Any ideas????. i guess i could put an overflow on my sump, but it sits right on the floor so it may be difficult.
