I have a 1 year old 57 gallon rimless tank swc 150 skimmer, refugium, 2 ai sol blue. originally started with 6 bulb tec light. I never had any polyp extension or great coloring (pale), so I switched to the sole blue. nothing has changed, all parameters are perfect with phosphates and nitrates at 0(used all different test kits) i do have 7 fish also. i set up a jbj 28 for a frag tank, as soon as i move frags into the 28 (it is loaded with cynobacteria, small skimmer and no refugium) the polyps open and start growing .it is lit by 1 kessil a150 15k. This is especially true with montipora, if I put a piece in the 28 the polyps open up and looks great, if i move it to the main tank polyps close up and coloring goes away. could my water be too clean????? any help would be appreciated.

I'd say your water is too clean. Unless you feed heavily you need something in the water or the polyps have no reason to extend
