Exposing SPS during water change

[Aquattro]

Rob, you and Denis seem to have no problem. Mine grows great, just not a lot of color. I am comparing mine to Jamie's original piece, and it's not even comparable!

I wish I could tell you what the secret is, but I have absolutely no idea. I did nothing special, standard Berlin method aquarium. I did dose iodine most of the time, but I don't think thats the key. Undetectable nitrate and phosphate, but I think that's pretty common in reef tanks.

I'm at 0 on both, still have a gray cross Everything else is blue or purple, just not that one.

Looks pretty low nutrient and/or very bright lighting (10k?) judging by the looks of the corals....if I didnt know better I would have maybe guess zeo as well. That is probably the key with it then (low nutrient/high light).....

I'm starting to get purple tips on the one I got from you, but I have it a half inch from the surface right beside a power head.

But back to the question! Yeah I leave mine exposed for 30 minutes every week without a problem!

I had from 12k to 14k over the years. 400w then reduced to 250w because I thought it too bright.

I had macro in a refugium with nutrients too low to grow Chaeto, so ya, low nutrient is likely key... though this suprises me. At times I've struggled to get corals to color nicely... just never the Purple Cross It had nice color from the day I put it in the tank till the day I took it out.
