seecrabrun Posted March 19, 2015 Share Posted March 19, 2015 I'm going crazy trying to figure out a retrofit overflow option on my nano to handle 50gph. Sadly the tank can't be drilled. It is housing a dragonet and I'm not willing to risk the established eco system to drill the tank. So I need something to retrofit, but I'm not having much luck. The HOB overflow boxes I've found so far are much too big. I found the eshopps nano and the smallest CPR one. I haven't bought them to try them, but they are pretty huge. I've researched and researched a DIY PVC overflow and bought the material, only to get lost in the building of it as it doesn't seem like it is actually going to fit in the tank. Can anyone who has come up with a solution help me? Please? Link to comment
Eckozulu Posted March 19, 2015 Share Posted March 19, 2015 What do you mean too big? Get any HOB overflow system you like then add a gate valve. A ball valve for your return pump. Good luck tuning!!! Link to comment
seecrabrun Posted March 19, 2015 Author Share Posted March 19, 2015 does the size of the plumbing on the overflow really not matter? Won't it be too light of a flow at some point that it can't keep the siphon? Link to comment
