Hi everyone, I wonder if you may be able to hepl me ? I have a heavily
planted aquarium 48 x 15 x18 inches. community fish . 24 C temperature. CO 2
system from yeast sugar reactor, Phosphates almost zero, Nitrates again
almost zero, but i get fuzzy algal growth on the edges of plant leaves. It
is more apparent on slow growing plants as the leaves are older I guess. The
growth was almost black or very dark green initially but after correcting
the previously fairly high phosphates and allowing things to stabilise it is
now much lighter in colour but still growing. Light is from twin
flourescents which are on for about14 hours per day.

Cheers

Ron
