Hanna PO4 testing

[Aquattro]

so, what's the likelihood that my PO4 is actually 0.00? First test with my new kit, and the results are questionable

The Hanna kits are super accurate but do not respond well to testing errors, even finger prints and micfro bubbles can give you a false reading.

If you're 100% sure you tested correctly your good to go.

Check out the Hanna video http://www.youtube.com/watch?v=kST09KWv9C0

Gonna take a sample to the store and retest. While 0.00 would be nice, I'm not confident it's accurate.

I do the three minute time as well and find it slightly more accurate for really low phosphate measuring, mine is usually .04

Well, got confirmation that 0.00 is accurate. NO3 is also undetectable. Cool. Sorry Tony

[Reef Supplies]
