H2O2 Dosing?

[George]

I wouldn't dare to try H2O2 in DT. It can kill good things along with bad things.
To keep clean water, a UV can probably do better job than most.
There are also probably a dozen harmless ways to control algae anyway.

That was my train of thought too, but he's adding 20ml/day long term and it's a damn nice reef!
