Zoas don't seem to like ligt directly from a Halide IME, and some LPS won't appreciate it either. What LPS corals do you have in?


lol!!!! could my sg being 1.021 do anything? coz thats what it is and what my lfs supplys me with. im going to buy a small pack of salt tommow to up it a bit

 If you are going into SPS, I'd strongly advise you to mix your own salt RO with a good brand of salt. LFS's will use whatever they can get cheapest at the time, and that often means stuff like AquaOne with no trace or macro elements in it to speak of... Reef Crystals, Tropic Marin and Red Sea Coral Pro are all well reputed brands
