Yes this was my next step, just ordered some 29% h202. I was going to run both. Feed bennies separately once a week (to keep it out my tank cuz the pump was clogging). Then dose h202 the following week to kill off and repopuplate. Might ditch the bennies altogether, not sure yet but def going to be using h202 whether it's standalone or with bennies. How much 29% h202 is supposed to be used? Ive never ran it before.Another point to consider is......You took out the bennies from your reservoir but....they will still exist in your blocks.
Bacterias are very resistant..
Is there any organic element in your nutrients? Even a pinch of humic acid could feed some bacteria that u previously introduced...
Im a totally new to rockwool, but if you think that those swings are caused by uncontrolled microbial activity, maybe goin sterile adding some bleach could stabilize the situation?
There are no other organic inputs besides the one benny product, unless the enzyme product falls in that category?
I also have 3% h202 lying around for other household use, does it make sense to dose this 9.6x higher and just use it?
