For about a year and a half I've been keeping mostly LPS corals with a large rock covered by GSP... More recently I've been getting bored with LPS so I've stocked up more on acros... It's just starting to cross my mind that my GSP rock could be having chemical warfare with my SPS and be detrimental to their health and growth... Is this something I should be worried about? I have a 180 gal tank.... are GSP's know to have chemical warfare with SPS corals??? Anybody keep a large amount of GSP's in their SPS tanks??? TIA...
