Nothing goes a planned. This weekend the clowns were going in an out of the RBTA. everytime I tried to get a picture they went back to the zoas and duncan. Now look at my pictures, you can see my on going battle with GHA. I got a crap load of snails at the LEAR frag show as well as a vacuum for the gravel and been doing more water changes and feeding less ReefRoids. It's working really well but---you see all that coralline algae on the back glass, the snails ate it as well as all the algae on the glass. Meanwhile the glass that is the front of the AIO sump they've left alone and the coralline on it is great.
