Hi,
Normally, I would take a whiff of it, if it smells bad, I owuld chuck the entire sponge.
I have changed like 80% of my water with seawater from the LFS. But still, I am noticing white spots forming on the rest of my soft corals and LR. I tried scrapping off the white spots..and placing it where the flow is strong. Is this the right way of curing them?
I'm not sure if the fast flow will spread the white spots to the rest of the healthy LR?
