The water surface in my wet dry is looking kind of slimy. Is this a sign of something bad? I got lots of cheato and I got some rock with some mermaids green wine glass growing on it in the sump. Also I am having a green algae out break. How can I control this? I cleaned the glass and really stired things up in there. the rocks were to close to the glass so It made it difficult to clean behind the rocks. I hope everything goes back to normal. 55 gal
