Allow me to go out on a limb here..you have a nitrate deficiency and to many
nutrients ;) To confirm otherwise get a nitrate tester and if it reads zero
then you have to either add nitrate supplement or cut back on supplementing
things like iron. How large are the thread like algae leaves? if they are
1-2mm it could be black beard algae, or hair algae but usually hair algae
can grow 8cm, just use a toothbrush to remove that, both are usually because
of excess iron. Algae is caused from what I understand is the plants aren't
using up all the excess nutrients so things like phosphates and iron is
still left in the system, alot of times this is caused by a nitrate
deficiency, and nitrate deficiency's are caused by excess nutrients and not
enough nitrate to create a "balance" if you will, so my suggestion would be
test for nitrate, phosphate is optional, but cut back on your dosing and
dose a little nitrate supplement if you want, but monitor nitrate levels,
once nitrate starts returning then your algae problems will disappear and
growth will turn a lot greener. Also on your plants, if you have any RED
leaves then you know it's a nitrate deficiency, otherwise they turn
yellow-green if not red. Hair and BBA is caused by phosphates and iron as i
understand it. Let me know how it turns out and the results of your test.
