I've had my scrubber running for 3 months now
(reminder viewtopic.php?f=2&t=584 )
The water parameters are still fine no detectable nitrate or phosphate
The scrubber is still producing plenty of algae but lately it appears to be a different type. It is brownish, soft, not very tough, more slime than algae really, but it's still doing the job.
Would this be because the tubes are aging now?
The tubes are 2 x 30w 3500k florescents
