The tank is about 9 months old. I have 2 clowns, 1 dotty back and a blue hippo tang.

Huh. Reef crystals is way better than instant ocean imo. So, I'm not sure why the corals acted negatively to a better salt. Unless you added extra additives after the water change.

No extra additives were added after the water change. Reef Crystals has higher calcium and magnesium. Maybe that has something to do with it.

I might be your salt mistake but is anybody seeing the bad health the SPS are in!
One birdnest has a stringy algae over it that looks kinda like Dino's.
Another colony has white tips from maybe high alk on low Po4.

Yeah. The bird nest is not looking so hot. The stylo has extended polyps in the BioCube. Up until this past week or so I have not had any issues with the corals growing. Ill post a picture from the past week.

I'll just throw my $.02 in and say it very well could be the alk number. While 9.8 dKh is within the acceptable range, it's a little high for a low nutrient system, at least by my experience. I have to keep my ULNS system at no more than 8 dKh, 8.1 tops. Anything higher and corals get aggravated.
Again, just me experience so take it for what it's worth.

What can I do to safely decrease alk?

It will lower itself over time, as long as you're not dosing anything to suppliment it. Just be careful not to bring it down too quickly. Water changes with your targeted dKh will also help, but again, I would recommend doing it slowly.

Dose anyone else think that maybe the added flow could be contributing. Low nutrients higher alk with added flow might up set sps. . And I know that if I place a lps in a higher flow section they won't open up all the way. I have to move them around a bit till the find spot they like.

Calcium is higher, magnesium is about the same, but in any case, neither is high enough to be any concern to corals. If higher alk with ultra low nutrients is the issue (usually causing burnt tips, not other types of problems), then the RC might have contributed a bit since it has a little bit higher alk.
I've not heard that higher flow compounds these alk/nutrients issue, but corals can certainly be in too high of flow, especially LPS.

I think the flow could b a problem and I was reading that certain type of coral that are lets say the down stream of the flow might no like what is coming at them from another type of coarl and maybe it declared war on the other coarl. I think it was like a cabbage coarl and a torch coarl something like that, ( just a thought)

Add more corals to suck up alk if that's the problem. Try cutting the flow down to the lowest preferably on a changing pulse and see how they react. Everything was going good b4 the extra flow right might have to acclimate them to flow just like light or water parameters.
