Refugium Question

[intarsiabox]

Well, I finished the plumbing, filled up the tank and ran everything for an hour. All was dry! So far I just tried the one ball valve since this is all I have at the moment but I made provisions to add a second one if I have to.

The tank is pretty quiet with only a little splashing noise were the water falls into the overflows. Unfortunately due to the design of the tank (got it used but cheap) the water has to fall about 4" to enter my Durso standpipe. The wife wasn't complaining so it can't be that bad!

Now just have to drain the tank and fill it with RO/DI.
