I got all my items today :) Here is a quick list of what i got

- Reef Advantage Clacium (Seachem)

- Calcium test kit (Seachem)

- Kalkawasser (Kent)

---------------------------------

I also tested water here are the results:

Nitrite: 0

Nitrate: 0

Ammonia: 0

kH: 10

Calcium: a little over 500 (500+)

-----------------------------------------

These looked very good, but I think i have found the reason my yellow polyps are closed: the High Calcium. I think i will lay of the Ca additionto get it back to about 470ppm.
