Yeah, I'm not 100% sold on this one.... err... well.. I guess I am since I bought one... lol. I do trust my elos Ca, so I'll go home and test with both and see what's up. The Phosphate and Alk ones seem great!

Sailfert is good for mag, I would definitely replace your elos if its going up wihtout adding. I like the alk & phosphate hanna but am not loving the calcium and feel I have to double check it with my sailfert, disappointing to have to have 2 test kits. I find if I focus on alk and keeping it steady everything else falls into place, unless calcium is really high making it difficult to maintain alk, I test alk, calculate dose and just dose calcium equally.
