Can't get my Calcium lower???

[A320 FO]

Besides water changes, any ideas how to lower Calcium, I have been doing water changes for weeks, but for some reason my Ca is hanging around 525. Alk is about 8.5 a little high also, and Mg is high as well, 1380. Everything else is good. Any ideas?

Just switched from instant ocean to Red Sea

Problem solved, Instant Ocean mixes between 500 and 600 calcium. It will come down now that you are using better salt.

Where did you gather this info?

I have been using instant ocean-reef crystal for years. I have tested my newly made saltwater many times and it's always spot on. Before I switched to IO, I was using better/ more expensive salts; red sea coral pro, brightwell, and etc. I noticed with the more expensive salts the cal, alk, and mg would be much higher than normal.

Let's not make this a debate about salt brands

I have been helping A320 FO for the past couple of months. I believe his calcium will stabilize in time. A320 FO just went through a large tank transfer and his livestock took a hard hit. IMO, their is nothing in his tank using much calcium, even the clam. However, I am very surprised its still so high.

How long ago did you remove the calcium blocks?
