Help with new test kits!

[blkhawk10]

I got myself a bunch of goodies yesterday, a couple being some new test kits. I tested my water today with the hanna checker for alk and a salifert for calcium both coming up extremely high. I tested the hanna 3 sperate times with all the same reading and the calcium 2 times with all the same reading. I was wondering if I should go with these kits readings as compared to my old API kits and start lowering the alk and calc?

I would go with the Salifert and Hanna checker over API any day. I have had the API alk start reading low on me before. I'm. Not sure if it became contaminated or just too old. But it was reading almost 2 dkh too low.

The alk Hanna checker has stayed consistent for me and very accurate I know this because I use ESV salt and mix my components separately by weight so every batch is exactly the same and I know for certain what the salt mix contains. Every time I use the. Hanna checker to measure it even with new bottle of reagent it comes in spot on.

By the way what's extremely high?

the alk was at almost 11 which is liveable I know, but I would like it in the 8-9 range wich the API was reading. The calcium was literally off the charts lol, the solution never turned blue. I've been adding 2 part everyday...5ml of alk and 7.5ml of calc. I'm going to be cutting the alk down to 3ml and the calc down to 4ml and see what happens.
