Hi all,
Hoping someone here can please offer some guidance. I'm running a 200l mixed reef tank which has been phosphate deficient for some time now. I've decided to start dosing kh2po4 (monopotassium phosphate), and have mixed up a solution. Now, I'd like to validate the solution strength using a Hanna Phosphate ULR Checker. But how???
Details;
Tank size = 200l
Container size = 800ml
Added 800ml of RO to container
Added 29.35g (Rounded to 30g) of kh2po4 to container
Dose size 1ml
to yield 0.128ppm phosphate
Testing device
HI-774 Marine Phosphate ULR Checker HC colorimeter
Range: 0.00 to 0.90 ppm
Resolution: 0.01 ppm
Accuracy: ±.02 ppm ±5% of reading
Required sample size = 10ml
How can I go about adding solution to the 10ml cuvette to confirm I've mixed up the right strength?
Cheers in advance!
Nick
