I have 2 questions...
1) Im building a sump out of a 20 gallon long tank. I want to build a top to it about half way across and then down into the sump to put a place for a drip plate and maybe put one baffle in. What parts do I need in order to plumb in the return from the tank to the sump? Do I have to use a bulkhead? I want to place one order for all of the stuff I need.
Does anyone have any plans/pics of the one you made?
2) I have an RO
system with three filters. When and how often do i change these out to make sure the water Im getting is pure? I had heard every 1000 gallons that you make. I have been keeping up with the gallons that I make, but this doesnt account for the gallons that is waste
