About a week ago, I noticed that my tank was growing a bit more algae than usual, and it wasn't the normal green stuff. I squirted in some of my Tetra brand algae killer, and hoped it would help, but it didn't
I have 5 nerite tiger snails and 2 or 3 MT snails, and they do a good job keeping the green algae at bay. They didn't seem to make a dent in the black goo, though, and within a few days my tank looked a bit like a black version of the tank in Finding Nemo after the fish plug up the filter!
Yesterday I gave it a thorough cleaning, and scrubbed everything off the tank decor. Even one of my fish looked like it might have algae on it (I didn't scrub him
Now everything looks much better, my fish look normal, and nothing is out of the ordinary. How can I keep this from happening again?
If it helps, I have a 10 gallon tank, with some fake plants, a plastic castle, and a chunk of petrified wood in it, along with ~15lbs of gravel. I have 2 mollies and 4 platies, and the snails I mentioned above.
