Accurate water test kits

Currently I'm using an API Freshwater Master Kit and an additional kit for GH & KH.

What other test kits are available that are more accurate than the API kits but that won't require you to take out a 2nd mortgage?

I like the API kits, but I have wondered about their accuracy.



Thx,

Martin

Lamotte are good, refills are cheaper, calibrations should be done for any test method, see the fert sticky on this.

This morning I checked Lamotte's prices. I think that while they might be one of the best brands for test kits if not at #1 ,their prices IMO unfortunately are above what many in the hobby could afford!

Later this evening I'll check more distributors since I only had time to look at one of them just to see if pricing is any different.


Thx,

Martin

One thing I never understood. I worked at a restaurant and we had to have a thing of water at all times in the sink that had x amount of bleach in it. We tested it with test strips and so did the health inspector when he came by. So if test strips are good enough for that, i wonder why everyone says they are so inaccurate?

Because they are terribly inaccurate. You were testing for thousands of ppm in that bleach water, and it didn't matter if you were off by hundreds.

Now if you are testing for .2ppm iron in your water and you are off by hundreds of ppm.......

Didn't think about it like that. Good point!
