The accidental overdose is well past me now, it's happened about 2 months ago so everything is back to normal. I lost no fish, they didn't even look stressed.
No, the black algae is not thread-like, it's just like brown algae, like rust. I read somewhere that it may be due to low nitrates and possibly low oxygen. I have increased my Flourish Excel dosing since about a month ago to daily 1ml doses, it may have something to do with it? I'll lower the dose or stop dosing altogether for a while. It's tough though, I can't easily scrape it off. I think I'll prune the affected leaves.
So you think 8 hours is still too much?
Anybody else? Any thoughts? Defficiency cause?
