Thanks for the Table! its really helped!
La Motte $20 kit may be in question? (premium aquatics, only showed the one test kit) Hmmm,
-----------
I had started questioning the salivert test because of deteriorating condition of my tank. loss of corals, loss of color,etc
------------
I think, its best, that I send a sample to Richmond to be tested at Alantis aquariums. (LFS I trust VERY Much) I will let you know..
--- BTW, since i started this post, I have been told (many times), salifert may have come out with a bad batch of test kits.
