I have two questions. The first is that I have lots of red algae (I guess) on my LR. None of it is on the sand or the glass. It is not slimy or powdery and it doesn't wipe off. Some of it seems to be growing of the rock a little. Any ideas?
Another thing, I have 4 places now that are a little smaller than a dime that are kind of whitish gray and they appear to be sponge like. They all have one fairly good size hole in them. Any thoughts on these? I can not seem to take a decent picture of these things in my tank for some reason........
Thanks in advance for any advice!!
