thanks for the offer tom. do you periodically clean it and if so how often?

The fresh water tank seems to stay clean. The Salt water tank seems to get a build up of diatom on its side that I wipe clean about once every 3 months or so.

well i have an update, i should change the title of my post because the tank that i was going to do is no longer, i upgraded to a 280 gallon tank 84"L 24"W 30"H. the boys had the 125 on the stand ready to plumb and it looked too small, i had already thought i would upgrade so i just decided to do it. i also got a larger sump 70 gal and i'll stick with a dart for my return, but upgraded to a barracuda for my closed loop. i'll be going with a different skimmer as well. traded in the ASM G4 and go with a euro reef skimmer possibly the RS250. i'll get some pics in the next couple days and post them.
