I think i have come to a conclusion about why my zooanthids are not doing very well in my nano. I have been using windmill water and running phosban. The phosban is a few weeks old now and algae is starting to appear again, so i think i have an excess of phosphates from the windmill water. Can an excess of phosphates cause zoos to not open? I did a water change with some RO water from Ace and everything did well after that, but since i have done more water changes with windmill....
