I made a few minor changes.
New carbon brand.
Alklinity from 8-7
One new MH bulb out of three.
30 extra minutes of light.
Now I have twice as much dinos as the last few months.
SPS corals are heading south quite fast. I have some dead already.
M Capricornis have lost some color going from bright red and green to gray.

This is simply a repeat of my previous findings and now I can say for sure that there is a link between Ostreopsis dinos in a reef tank and SPS coral health.
There is a point where your SPS corals show signs of no or slow growth.
This can creep up on experienced tank owners becasue the dinos will be very hard to detect if you are uninformed.
There is another piont where your SPS corals stop growing and slow tissue necrosis will take place.
There will be brown patches here and there with clear surfaces in between.
Then there is a point where toxicity is at a level where corals can die in a few days with a fast tissue necrosis or show marks of severe discomfort.
Most of your sand will be covered in dinos and at least some of the live rock.

Did someone say dinos are difficult?
