I've tried several varieties of test kits with mixed results. I absolutely love the hanna's. I'm still growing to get used to the Ca one, but the Alk and the PO4 are supreme!! I find that with the Calcium one, you need to be VERY precise with your measurements in order to get proper results. I've used the same methods for 3 tests in a row and got results form 305-520. I'm starting to get used to it though. I've got my lines down pat, and methods perfected... sort of. I'm starting to trust it more and more.

Alk and PO4... wicked!!

Magnesium... not released yet is it?

So far I have hanna phos and alk checkers, with calcium on order. Alk and phos are great!

There have been reports that some(?) calcium checkers are way out to lunch, but the alkalinity and phosphate ones are getting lots of good reviews.

I'm not ready to say this for sure, but I feel like the Calcium checkers take a little getting used to. After a few more tests I'm going to test to a known solution, and see what my results are.

What is there to get used to? I haven't used one.

I have alk anda phosphate. Both are great.
regular alk testing is simple,fast,and cheap, but. hanna's decimaal readings are Helping nail Down more frequent smaller dosages.

Phosphate i could never get an accurate reading and i am really glad i got it.

I love my hanna alk & phosphate checkers, accurate and easy to use, I don't like the calcium checker, pita.

I use elos for ca, alk and mg and find the kits to always be very consistent. I suppose I never know if they're accurate but i think water consistency trumps having your levels at precise spots anyways. these kits are very easy to use and my eyes have no issue at all detecting a colour change. kits that have you comparing colours stink i think but these have distinct endpoints.

I bough the phosphate checker and used it once. it read 0 which seemed unlikely to me and I haven't bothered to use it since.

You make a valid point... And no one has sold me on them LOL so I think ill stick to my Elso kits until they have made a better checker
