Better question, how are those chalices doing? They look huge!

They all seem to be thriving so far,... I had one that was losing its color so I moved it into a shady area and a month and a half later she's looking vibrant again,... Overall I have no idea why they seem to like my setup but they do,... Hammers and bubbles on the other hand are my nemesis lol

That's weird, I have exactly the opposite problem. Most everything grows but chalices. And I use to be able to grow them. But something specific to them is not working right now. You seem to be having the reverse thing going on.

A friend of mine had some issues with sps, so he sent a water sample to these guys-
Aquarium Water Testing
The result was his potassium. Apparently synthetic salt mixes are generally low in potassium. He has been dosing it, and his corals are improving. I don't know if this and his issue are one in the same, but who's testing for potassium?

I'm sure not. That's a thread on its own. Vitamin C is another topic I would like to read more about.

Interesting site. A bit expensive but laboratory grade measurements would be wonderful to have.
The site had his to say about Potassium:

In natural seawater, potassium is a non-conservative major element with a concentration slightly lower than that of calcium. It is a component of aragonite, and regular dosing has, within the past several years, has been implicated in improving the blue coloration of numerous varieties of small-polyp stony corals; the benefits of potassium supplementation are potentially two-fold, then: provision of an element that is 1.) incorporated into the skeletal material of corals and other reef-building organisms for purposes of growth, and 2.) incorporated into pigments that enhance blue coloration of small-polyp stony corals. The importance of potassium to marine organisms is most apparent when beginning to dose it in aquaria with depleted potassium concentrations and/or in which the sea salt mixture used is potassium-deficient; in such cases, changes in the appearance of many corals may be observed within the first weeks of regular dosing.

I visualize this as a scene from CSI, all white lab coats, but in reality it's probably a shirtless guy with bottles lined up on his cracked bath tub.
