Is this GSA

Ive only had green spot algae on my glass occassionaly and never on plants, is this what is growing on my Anubia leaf ?
If it is then why is it only on this leaf and none of the others (15-20 leafs total)

It sure looks like the same stuff (GSA) I had on my anubia. So I am going to say yes you have some GSA. I only had it on like 3 of 15 leaves, my guess was those 3 leaves had more direct light. Nerite snails took care of that for me. Since then I've corrected my phosphate levels and it hasn't come back.

looks like GSA to me. maybe diatoms..... try reducing you photoperiod a bit if its above 6 or 7... how are your co2 levels?

I think that's the problem, lights on at 7am and lights off at 4pm so 9 hours total . C02 is a couple of notches under where the fish are gasping . Drop checker is close to yellow.
