Running 8 fans? how much evaporation do you have? How long has your tank been setup this way?

I just add 4 more fans yesterday. I used to run 2 on the tank and two in the sump area. I have no idea how much evaporation in the tank cuz i have my RODI unit hook directly into the sump

Your right about that,its not very often you get anything free for this hobby! Im going to use a dart needlwheel skimmer on my tank.Im having a friend build me a body with 18" acrylic around 36" tall reaction chamber. the skimmer will be around 5' total height with bottom box,riser cone,and collection cup included..Im going to buy the dart NW conversion for one of my darts that I allready have.Should be sweet and at a 1/4th of the price of similar ones!

ooops I meant he is building the skimmer with 14". I cant afford the 18" prices.
