So I have 20 gal
tank set up for just over a year now, I started adding corals a few months ago which are all doing great, my frogspawn is actually growing a completely new head at the moment.
So I have some White Sea sponge that came on some premium love rock I bought a few months back. The stuff is growing like crazy all over my rocks. So here's my question, a friend had told me that the fact it's growing so much means I have to many nutrients in my water, and that's bad? Is there any truth to that? Are white sponges bad for my tank or harm and of my corals?
