HI everyone , just looking for a bit of advice ,
i have had my scrubber up and running for about three months it is filtering a 40g mixed reef tank
the specs on the scrubber are
a 6" by 8" double screen/double sided
the water is fed to it by a 1000 lph pump and the over flow from the tank which i estimate to be probably about 700 lph by the time
it gets to the scrubber .
lights are two 35w cfl at 2700k which is the highest watt and the lowest temp i can find in this part of the world .
on the 18 hr cycle.
the problem is that i haven't been able to eliminate the gha in the display with scubber alone and i cant seem to get consistant green growth on the screen
it always starts brown and then when i do get green coverage it comes off really easily even with the lightest cleaning and i have to start from square one .
i have attached some pics .
hope you get the idea .
what am i doing wrong ?
cheers dan
