I've been giving serious consideration to dosing H2O2 lately to kill off some of this GHA that I've let get a bit out of hand. I have an ATS and I would like, if possible to not kill the algae that is growing in it. Is think H2O2 breaks down pretty fast in the tank. Is there a time period I could leave the ATS off each time after dosing where my ATS algae would survive?
