my screen has 950 gph going over it,I dont think a 1 month old mag 9.5 needs a vineger soak,trust me, my flow over the screen is strong from one end to the other, with water pooling 1" on the bottom of my scrubber box (i should say flowing strongly) to my 1" bulkhead, I hope this photo shows this. AGAIN the lights are as you recomended on your post...2700k 24watt each with 2 units one on each side, 96 watt total( REAL WATTAGE), they are maybe 50 days old,I feed 1 to 2 frozen cubes of rods food. I can only assume youve never dealt with this kind of algae before,youve never spoke of it. IMO this type of filtering isnt going to work for everyone,it certainly is not working for me,and ive tried everything youve suggested to everyone, it will make baby copeods, and thats why I havnt givin up, my mandarins love them, maybe someday Ill get GHA, but obviously Im doing something wrong,just dont know what,could be I need to buy the SM100
