New Hanna phosphate checker

[Myka]

I will be interested to hear how this tester compares to a Merck kit. I like my Merck kit, and I find it very easy to use and read. It sounds like this tester is a bit fussy. Thanks for the review!

Ya, but your phosphate level (in a reef) should be lower than what the Salifert kit will detect.

Here's a review

OK here are 4 measurements off the same water sample from a freshwater planted tank:

Sample 1: 1.34 ppm
Sample 2: 1.06 ppm
Sample 3: 1.35 ppm
Sample 4: 1.35 ppm

After running sample 2 I realized I had not got all the reagent powder into the reaction vial as some of it spilled. So far it seems that the readings are fairly consistent from one measurement to the next if I through out the one bad measurement. This says nothing about whether the measurements are accurate or not.

Next: to repeat the measurements with a saltwater sample.
