Lost instructions for the Salifert phosphate test
 

Can anyone help me out, how much tank water, how much dry reagent, and how much liquid reagent to use?

Thanks.

1) Add 10ml of water in the test vial
2) Add to this 4 drops of PO4-1 and swirl for 10 sec.
3) Add to this 1 level scoop of PO4-2 reagent and swirl for 30 sec.
4) Place the open test vial on top of the color chart on a part of the chart which is white and compare the colors looking from the top.

The phospahte values are in ppm phosphate.

0.03 - good
0.10 - critical
0.25 - coral growth retarded
0.50 - your hooped (it doesn't actually say that I just added it)

Should you require an even higher sensitivity then double the water sample and the reagents. The scale should then be divided by 2

Hope that helps

weird- my kit says to add 6 drops of the PO4-1 drops. :confused:

*Hurries back to double check*
Nope, mine says 4 drops. I bought mine about 4 months ago from J&L so maybe they have updated??????

Thanks.
