I've actually got a similar issue in my tank, with algae. I've tried the whole light thing I've even tried marine glo lights to try and kill it. No Luck. At one point I even had black algae. the interesting thing is that my silicate levels are pretty low and so are all other levels. I am a bit slack on my water changes and sometimes go up to 4 weeks between changes. When you guys say do not over feed what is considered overfeeding? I feed my tanks at most twice a day. I do have some tiny fronts in my tank now so it seems like they might trim it down?
I've also got 2 Synodontis nyassae and 2 Synodontis multipunctatus These guys really do not seem to like the algae either.
any ideas?
