hi all,
i'll try to keep it short!
heavily planted hi-tech tank, 100% ro water, gh 5, kh 9, EL ferts, .
problem is, i noticed green algae was spreading quite quickly over everything and, more recently, BBA has appeared in hi flow areas.
the tank ph sits naturally at around 7.1 which, by chart, is in the sweet spot for co2 but that also means that for a while the regulator has released virtually no co2 at all.
i know i should set my ph so co2 will make it drop by 1 point but that would increase my kh too and i'm at 9 already so i'm a bit worried to keep pushing.
in adition to that, i realised the other day my nitrate crept up to 60-80, so i'm cutting on macros and doing more water changes but i'm not sure just lowering them will sort the algae issue.
any suggestion appreciated.
thanks!
