My phosphates are high

My phosphates are .5 in my 12g frag tank with all sps in it. Can I do daily water changes to lower it or will it shock them if i get it down to fast?
 
shouldn't be a problem... might want to check for phosphates in the new water
 
as long as the chemistry of the rest of the water is the same, your SPS will thank you for those water changes.

you DID mean .05, not .5, right?

.5 would make for some very UNHAPPY SPS
