Fs. Hanna ultra low phosphorus test kit $40
 

Priced to sell. Bought brand new from jl for $70 plus tax.
Used twice for test. Easy to use for testing phosphate.

Bump $30
 

Someone asked about reagent exp. Expired Nov 2017. Didn't expect them to expire so fast. Bought the kit less than a year ago. 25 pack is around $16. 4 pack of reagents still included.

Interested. Why aren't you using it?

Wanted to confirm my laziness was the reason for algea. Did a test once I removed some new macro rock I suspected of leeching. Then a few weeks later of gfo and cleaning my nasty sump, phoshates were almost undetectable.

Bump $25
