Algae scrubber?

[tmccaff]

I just got the Icecap Algae scrubber small and I am guessing water should go through it slow. It says run the lights half does this mean run it 6 hours instead of 12 or just one light?

Only IceCap could say for certain!

Slow flow don’t sound right. Half the lights or half duration maybe some new development but I did my DIY one full blast, no problem. I’m assuming your trying to lower N & P because they are way too high?

Quick edit - my full blast was 12 hrs a day if I remember correctly, definitely not 24hrs.

Ice Cap's recommendation for the small is 250 gph

from instructions:

Using the red valve on the feed line, close the valve slightly to Lower the flow till the water trickles down the screen.

Helpful tip: During the first week after installation, only use half the lights to allow the screen to seed.
