hanna cal checker?

[aznnutty]

anyone using these and having a hard time with them?

i tested my water twice two months apart and both times my cal was over 530! and im currently not dosing. i'm using IO salt.

not accurate, I have the alk, and Phosphate and every time I use it I get mixed results. I dont trust it at all

I have both the AlK and Cal hanna checkers and i am throughly pleased with them. The Alk is much easy to use but after using the Cal checker over time it more accurate. The biggest issue was the level that i was putting in my vial. It is really important to make sure the meniscus is measured properly as shown on pic "A" below. When i first used the Cal checker i was not doing this and my readings were very high. Now my API and Hanna checker are practically spot on!

so your saying pic B is what im aiming for? i like that its digital, i just want it to work

No, A would be the correct way to read it.

"Properly " is shown in figure A.

So I did it the proper way. I'll pick up a second cal test kit to find out

I get high readings with my CA checker if my RO water isn't good quality..... I'm going to get some lab grade DI water so its always consistant readings.
