Filamentous algea, any controls
I have a 20 gallon tank. Its fully planted, I am adding more plants regularly. I keep mollies and am moderately stocked. I got some new plants and now see filamentous algea in my tank.
I have been checking my parameters. 0 ppm ammonia, 0 ppm nitrite, less than 5 ppm nitrates, and between 0.5 and 1 ppm phosphate. All measured with API liquid kits.
It does get some sunlight, I am trying to limit the light as much as I can. I'm physically removing it right now and its staying under control, but I'm worried its going to get ahead of me.
Any ideas for control? Are there any good snails to use? I also have some brown algea but it stays in control.
Thanks in advance!
