I've run diluted samples many times, this hanna 736 checker has probably run through close to 500 tests.
The sample from last night was so blue I diluted my test tonight 10:1. It read 131...
131x3.066/100= 4.016ppm po4
I snagged a 2 liter jug of Phosguard a couple days ago for a few dollars from a guy breaking down a tank. I prefer GFO but I'll burn this stuff since it is more aggressive and was essentially free. Though, at current levels and absorption rates of .87mg/g it would take 20 liters of Phosguard to remove all the phosphate. I'm hoping not much has bound to the rock yet and that most of what I am testing resides in the water...
My RODI is going full tilt so I should have water ready to do a 400gal water change by Friday night. I'm not going to burn any media until that is done.
I may need to setup my Lanthinum Chloride Reactor to pull this much phosphate out of the water.
