Bleach kills root rot end of story lights out. Krunchbuble uses it all the time and swears by it. I use h202 because it adds more oxegyn to the res.
what was the rate per gallon you used I cant remeber what thread that was in.
initial root rot kill - 2 ml per 10 gallons
to maintain to rot - 1 ml per 10 gallons, every other day...
I would dump it out, and rinse it a few more times
I've been battling what I believe to be brown algae. Someone recommended I add bleach at 10ml/gal every two weeks. This was well over a week ago, and I've seen no ill effects so far. Keeps the reswater nice and clear. FWIW, I'm using RO water and recirculating my nutes. You're under 2ml/gal. Don't think it'll be an issue unless you're using tapwater that already contains a lot of chloramines.
Sorry. Probably wanna skip back to the first page.
No worries man, Thank you for pointing me the right way. I noticed that you are using those tuff boxes. If they are the ones with yellow lids then maybe there is light sneaking through the lid...which may lead to badness. Just a thought.
Cheers,
