Hey,
I've been struggling with phosphate issues for a while, and have been using GFO.
I set the reactor up in the new tank last night, and before this I tested the phosphate, it was reading 0.90, so I assume it was higher than that.
This morning I tested twice, and it was reading 0.22 both times.
I then took a sample to my LFS, and they tested the water 5 times, and the readings were as follow, 0.78, 0.24, 0.90, 0.20, 0.90. All from the same batch of water, and the tests were all performed exactly the same, I was watching them do the tests the entire time.
On the very high readings the water did not turn the shade of blue that you see on these tests when the phosphate is testing so high.
Both the testers themselves are under a year old, and the reagents were all in date.
My (2) corals are doing very well, so that makes me think that the phosphate is not too high, but I'm not sure.
What should I do to get an accurate reading, and is this a common issue with the Hanna testers?
