hey
Im on the way back to this forum with a new 360liters tank...
the new floating scrubber is very impressive and I will try to make a scrubber that is placed about 3cm under water and lots of watermovement and air bubbles arround it...
indstead of the greengrabber stuff I will cover the sides of the box with crushed live rock and small koral pieces... would you guys think this will work?
