What's a good starting point for H2O2 per gallon in my res? My temps hover around 71-73. Wish I could get it lower but even after insulating it that's as low as it will go.

SM90 for res. Or try Grozyme for roots in warmer temps.

I recommend a fan for top of res lid blowing heat out, or an open res lid in dark room to drop temps. You can drop 10F res temps by doing this.

It depends on your H2O2 - is it 20%, 50%?

For 50% H2O2 I use 25ml per 100L every 3 days. Res stays crystal clear. No lid on res, never check temps or even care what they are.

Be careful with 50% it will eat through your skin.
