If you have phosphates in an SPS tank, can it be harmful to the SPS coral? I have a consistant .25 of it in my tank over a couple of months and am going to get my first SPS's in a week. People have told me to keep it as low to 0 as possible but what about the coral? DOES IT EFFECT THE CORAL GROWTH IN ANY WAY? I know you will get algae but i can fix that up with a little bit of flow.
