I've noticed this type of grow on my roots and changed the reservoir water plus added chlorine and H2O2. Now it's back again.
I've tried beneficial bacteria, but that seems to actually worsen the situation
My PH keeps going through the roof. The airstones and the bucket walls have brown gunk on them, the same as the roots.
My reservoir water is around 23 Celcius, which i think is around 74F. I've tried really hard to keep the light out, which is why im adding the other pic too.
Can anyone help with any advice?
Thanks
