I have a 29 G tank with 5 false julii corys. I usually feed them 10 bottom feeder pellets per day (2 each). I noticed on one of the plastic plants yesterday that the leaves were a bit brown tinted and thought I would clean it in a few days. Overnight, it seems, green and brown algae have taken over the plastic plants, and the hard decorations. There is no algae on the glass yet. I tried scrubbing it this morning and it does not come off easily. I plan on doing a large water change tonight (Ammonia 0 nitrite 0 nitrate 30). Should I soak the plants and decorations in bleach or vinegar? I want to get it under control before it completely coats my tank. I am open to getting an algae eater- my lfs has cherry shrimp, ghost shrimp, nitrite snails and mystery snails, would these solve the problem? If I was going to add something new to my tank, I would need something hardy because I am a beginner. Thanks in advance.
