Phosphate Test Kits.
So I have been having some issues with my Hanna Phosphate (ulr) checker (I think) so I will run the test and get a result say .34 for example, I will run the same test 3 to 4 more times with the same water samples and I am getting different results each time. for example one night I tested and results were:
So I decided to order a RedSea Phosphate Test kit. tonight when I tested the phosphate from the Hanna was .34 and the RedSea tested between .08 and .10.
I dont expect the same results, but they should be close, further more when I test with the hanna with the same water the results should be the same.
Anybody else having this issue?
In the past I have taken water to the LFS but they use one of those all in one checkers and the results are so far off in every category I found it not to be reliable.
