Ditto!

How many mL/Gallon?
Dosed at any particular time of day?
With a doser?
Regular ol' 3% drug store peroxide?
All at once or multiple do sings/day?

I get cyno in one of my tanks as it heats up during the summer. Normally 78 degrees - no cyano. 80 degrees - cyano starts creeping in. What I found was that even when it cools back down to 78, the cyano will still hang around. So I dropped the temperature down to 76 (even as low as 74) and the cyano disappeared! No negative effects on coral or fish. Give that a try before adding chemicals of any kind.

I just wonder how much the or fluctuates when dosing peroxide

Ok. Here's my dosing schedule. First I mix up a batch of hydrogen peroxide. I buy 30% stuff by the barrel for my pond, I dilute it 50ml to 450 ml ro/di water. This makes it to approximately 3% I think. Then whenever I'm doing my daily "check the sump room to make sure nothing is leaking", I'll stick 5 - 6 tablespoons of my mixed H2O2 straight into the sump. My tank volume is approx 350 - 375 gallons in my best estimation.

awesome thanks! Once I've got my whole system back on track and I sort out a better nitrate control system, I'm going to try that out as a regular maintenance item. 6 tablespoons is about 89 mL, so that's about 0.25ml/gallon per day. When you think about it, 89 mL of 3% in to a 350 gallon system is like diluting an already highly diluted solution another 15,000 times, and it's a compound that all eukaryotic cells have sophisticated enzymes in place to rapidly decompose. I bet at those concentrations it's not even directly killing the visible algae or the bacteria, but possibly oxidizing spores in the water column or destroying dissolved organics that wouldn't/haven't been picked up by your skimmer. If you've got even the tiniest bit of organics in your water, at that concentration it's probably completely decomposed before any of it reaches your rocks.

PS, where do you buy 30% H2O2? I thought only laboratories could get it that concentrated?

I bought mine from a health food store.
