So the last few months I've seen less & less PE on my SPS and a lot less growth. Not knowing what was going on, I finally decided to do a bunch of investigating & testing. No busted magnets, everything tested out normal or in range except....
My tank tested positive for Copper! Using the Hanna Hi702 checker, it read .15 (reagent expires 2025). Now I know that isn't a ton, but I'm sure it is enough to throw my SPS off. So I tested my RODI - 0. I tested my other tanks, and all 4 of them read some level of copper from .07 - .15.
So I add some TM Pro Reef Salt to the same batch of water that tested 0, and it tested .20!!! 1.025 salinity. Fearing the salt was contaminated I ran a different test on a batch of water using Fritz Pro Reef & it tested .14 @ 1.026 salinity & .76 @ 1.041 salinity (knew this was going to be way off as the reagent didn't fully dissolve in that much salt)
After letting the new salt water sit for several days I tested it again. TM pro came up us .01 & Fritz came us as .02.
How is any of this possible?
@Hanna Instruments ???
So right now I'm very confused & concerned and ordering ICP tests since I don't trust my Hanna.
Thanks
