Hanna PO4 testing

[Reef Supplies]

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

I'm at Proreef getting the results confirmed, and I say "Great, now people are gonna want to know how I do that"

No idea. Big glass box, 1/2 quality rock per gallon arranged to not trap crud, tons of SPS, lots of feeding, 50g water change every other week. Run zeo and often remember to dose the stuff and jiggle the rocks. Big ER skimmer cleaned often. Pretty much same stuff others do, nothing special.
