I would like to try a Hanna PO4 colorometer when I have some spare cash

I use the Hanna Phosphate Checker for P04. I used to have high P04, but now with the use of GFO, it runs mostly between zero and .07. For N03, I use API (not accurate for low readings) and Elos. It has been consistently zero for some time now. I have never used the Seachem test kits, so can't say how they compare.

I only recently started adding SPS, but it is growing very nicely, so I guess my tank has some nutrients.
