Peroxide - you guys will think I'm nuts

[Reef Pilot]

Does dosing hydrogen peroxide have any effect on corals? I thought some corals culture photosynthetic algae?

Also, don't tangs and some other fish need some algae to graze on? I don't think just nori is good enough for them.

I found the best solution to beating excess algae was to get the phosphates right down to zero (hanna checker, not the color test kits) with HC GFO. Then any hair algae would literally let loose, and was easy to clean up. But as soon as the P04 got up to near 0.1, it would reappear. And SPS does best when it is near zero.
