I have a 40g water Volume system with mix of SPS and LPS and softies that’s about 8 months running. I’ve had issues with elevated calcium due to bad testing twice already and am having corals recede on me again. I suspected something was off since my tests showed good water Params that have been stable for a good while but my zoas started closing often and my chalice started receding and I lost one acro (though most are happy).
Params:
8.8 dKH alk (Hanna)
440 ppm calcium (Salifert)
1320 ppm magnesium (Salifert)
5 ppm NO3 (Salifert)
0.02-.1 ppm PO4 (Hanna ULR)
So I started suspecting something funky so I did a Triton ICP test and got back Params today. It says calcium is 520. That’s second time I’ve had this. Before it was because I was using my Hanna calcium checker which is garbage with distilled water or RODI I had made up and it would read in this range while my Salifert would max out. Triton said around 520 then too.
Meanwhile I’ve been following my test results and had a Neptune DOS adding 9.5 mL of soda ash during the dark hours a day with 21 mL of calcium chloride added during the light hours. I didn’t like this disparity but I was following my results. My testing has shown calcium slowly coming down over the last two months from the aforementioned first Triton test.
I’m at a loss for what to do to make sure my calcium is in check. Any thoughts oh wise one? [emoji1] Teach me the ways!
