My tank has been running for about 5 months now and the water parameters are good with NO2
=11. But I still get a minor algae problem on my argonite substrate.
If you look at the photo, it is not a major problem, but rather very unsightly. I have replaced some new argonite over the top, but the algae will just grow on it within a couple of weeks.
My question is, is anyone out there having similar problem or just me? And is there something I can do to eliminate this?
