    I have a 33G, 2wpg, 30ppm CO2 mist (ref. solution in dropper), EI (tap also loaded with NO3 and PO4), TMG for trace, 2/3 water change per week.

    Plants are Java ferns, lots of crypts and anubias. They are all growing very well and pearling in an hour or so. It is very densely planted.

    Recently I've been experiencing something like GSA but with BGA properties. It is mainly bright green spots varying in size from 1mm to 5mm. The algae comes off very easily but does not smell at all and is limited to the Java fern leaves. Water circulation is good all over the tank.

    I thought GSA but previous experience was GSA is stubborn. My tap is 5ppm PO4 and I'm adding 1ppm via KH2PO4 3x week.

    Any ideas?

    I've seen softer GSA in the past, with good CO2, it's always gone away, it is more likely to form on Crypts and Anubias, but with good care, it should go away.

    Try making a mix of 25:75 Excel:H2O and spraying this on the leaves when you doa large water change and exposure the leaves.

    Let it soak in for 5-10 minute and then refill.
