hey guys, first off i have been running a scrubber on my 125g fowlr for over a year now and never looked back! thanks santa monica for all you've done. just looking for a little input on an idea i have on making my screen rougher. im thinking of sand blasting it after working it over with a hole saw i have noticed the saw leaves some slick area it dosent get at so maybe blasting it will give more bite? any thoughts?
