Been dealing with this brown stringy algae for about a month now, generally didn't bother me but now its starting to cover my corals and get worse. It just feels that Im getting more growth in my display than the scrubber.

Here are my specs so far
0 TDS on 2 different cheapo meters
0.03 phosphate on red sea test, 0 on salifert
0.05 nitrate on red sea, 0 on API (both nitrate/phos show 0 if I dont feed heavy that day)
PH 8.1-8.3
460 calcium
1400 Magnesium
9 dkh
Reefbreeder LED 12 hour cycle with max 55% blue, 25% whites

Run algae scrubber that is growing, tried hydrogen peroxide dosing, chemiclean, 72 hour day blackout period. Only time it goes is when lights go out, not sure if its due to clean up crew going at it or cause of no lighting. But if anyone can help identify it so I could attack it properly, or has a solution would be much appreciated.
