I’ve had this tank up and running for 2 years now, everything in it grows well, and there’s no other types of algae except for the one pictured which covers the plants and kills them. I read that high phosphates cause this, so I tested my tap water (London tap) and found that my tap water had enough phosphate to sustain plant growth. Due to this I switched to a fertiliser with no phosphate. This did help to slow the rate of its growth - in a week or two it would cover the glass, now it’s only a small amount on the glass over a few weeks. However it is wrecking my plants. I’ve pruned it all out several times but it just comes right back once growth is a couple of weeks old.
I would really like to get this under control as I am setting up a larger tank soon and would like to transfer the plants to that, but obviously healthy and without this issue.
A bit more about the current tank:
56L VOLUME
80L 35D 20H cm
C02 injection
1ml TNC no phosphate daily
50% Water change weekly
Eheim thermo filter
Twinstar m50
Twinstar 60EA settings:
1:30 0
1:35 5
3 10
3:30 40
8:30 40
9 10
9:25 5
9:30 0
Stocking:
Cherry shrimp, 1x neon rainbow, 5x celestial pearl danios, 2x Pygmy cories, 1x Otto.
I have tried less / more ferts over months, 1ml a day seems best for plants. I’ve tried less lighting, but plants didn’t grow. Don’t know what else I can do but really want this under control as it’s ruining the tank.
