I've been using SeaChem Reef Salt since I set up my tank a bit less than a year ago. Early on I would test kH and Ca of new water after I got the salinity to 35ppt. It always seemed consistent so I stopped testing everything but salinity of new water before using it.
I was going to do a water change today and tested the tank water before hand. The test results using API test kits were:
Salinity 35ppt
Ammonia 0
Nitrite 0
Nitrate 0
Phosphate 0
Ca 480
kH 9
Mg 1350 (salifert)
The calcium never runs that high in my tank so I decided to test the new water:
Salinity 35ppt
Ca 600
kH 10
Mg greater than 1500, would not read on salifert test
I remembered I recently got a 60lb box of Reef Salt from Amazon and realized the Ca has been creeping up since I started using it a couple weeks ago.
I took a water sample to the LFS, they tested it and verified my results.
I think something is off with this box of salt and am wondering whether I should use it. I'm working really hard to maintain stability in the tank to get the best coral health possible. If I'm trying to keep calcium in the low 400s, it seems like every time I do a water change with this salt it's going to throw the tank's chemistry out of whack.
Am I missing something or do you consider this a problem too?
Thanks!
