I just bought this sponge and I researched everywhere(mostly). I just want to know should it be shaded like I have it or out in the light. One website called it a flower sponge; but I can't find anything, I know most sponges need shaded areas, but the key word is MOST. It started to grow some red algae on it so I moved it under these rocks. My phosphates are zero so I really don't understand that either, I just started skimming so maybe that's partly why.
