 one rock with polyps covered in hair algae
I have a 24G nano, a few months ago I got a nice rock covered in button polyps. Now this rock is covered in hair algae. It was spreading about 1 1/2 months ago to other rocks. I took them out, cleaned them all off and they are fine.. I use distilled water. I even used some phosphate remover since then. Everything else in the tank looks fine. All my levels seem OK. NO fish, 2 snails, a few hermits, and a few corrals. ( tons on pods swimming everywhere that i just noticed last week) No other rocks in the tank are have the algae. The hair algae keeps growing from only that one rock. I cant get rid of it. Any ideas? I am thinking the lights may need changed because I bought the tank used around Dec. This is the only thing I can come up with. |
