Generally make sure ammonia and nitrites at zero and Very, very low level nitrates and phosphates. Make sure ur ph is stable from 8-8.4 and kh above 7. These are general rules--acclimate by placing low then move higher after a couple weeks. If these are new or in the future u want to dip ur corals/zoas too w either lugols or coral rx to get rid of critters. Some ppl also use bayers and furan for zoapox. Most zoa/paly are quite hardy and so more forgiving w mistakes. Main thing always check your water parameters.
