If phosphate is present in too high a concentration there may be an increase in growth of undesirable algae and if the phosphate level is higher than 0.04 mg/L the growth rate of corals and calcareous algae may decrease by as much as 90%.
Washing fish food (a rich source of phosphates) after thawing can significantly reduce the input of phosphate, and using a high grade, phosphate free activated carbon can also help to keep phosphate levels as low as possible.
The Salifert Phosphate test kit detects, in less than 5 seconds, the level of phosphate present.
There are two different ranges within the kit: a low range for phosphate-phosphor from 0.01 - 1 mg/L and a medium range for phosphate-phosphor from 0.02 - 2 mg/L.
Sufficient for 60 tests.
Can be used for marine, fresh and garden pond water
Erroneous results might be obtained when the carbonate hardness is higher that 20dKH. This corresponds to an alkalinity of 7meq/l. Normally the carbonate hardness is well below the above mentioned values.
Warning! Irritating: PO4-1 contains < 3.5 M HCL.
R36/37/38: Irritating to eyes, respiratory system and skin.
S26: In case of contact with eyes, rinse immediately with plenty of water and seek medical advice.
Add with the syringe 10ml of water in the test vial.
Add to this 4 drops of PO4-1 reagent and swirl the test vial gently for 10 seconds.
Add to this 1 level scoop of PO4-2 reagent and swirl the contents gently for 30 seconds.
Place the open test vial on top of the color shart on a part of the chart which is white and compare the colors looking from the top. Read the corresponding phosphate content. An intermediate color corresponds to an intermediate phosphate content.
The phosphate values are in ppm Phosphate. If you prefer a reading in ppm Phosphate-Phosphor then divide the reading by 3 or use the table given below.
Higher Sensitivity Should you require an even higher sensitivity then double the water sample and the reagents. The scale should then be divided by 2.
Salifert Salifert is a Holland base company that produces top of the line test kits as well as tank additives and foods for marine and reef aquariums.
I needed a low range test consistent and clear to help with algae and coral growth, this was not it, after trying more than 5 times i got results that were inconsistent and not even the right color, the test was shades of blue and i got some odd green color.

I needed a low range test consistent and clear to help with algae and coral growth, this was not it, after trying more than 5 times i got results that were inconsistent and not even the right color, the test was shades of blue and i got some odd green color. Stating it does low range was misleading as well, they just tell you to double the dose then divide by a number to get the low rate which is still tought when i cant even understand what shade and color the original color was. When i guessed it was at 0.10 I bought the Hanna colorometer instead and it tested 0.38 instead! which made more sense because i still saw algae and slow coral growth.Hide
This test is simple to use...very clear directions. Also a low range test, however the scale is hard to read. If you have glasses, wear them, because you"ll need them to distinguish between the very similar shades of blue....one thing for sure though, you can definitely tell if your phosphate...Read More
This test is simple to use...very clear directions. Also a low range test, however the scale is hard to read. If you have glasses, wear them, because you"ll need them to distinguish between the very similar shades of blue....one thing for sure though, you can definitely tell if your phosphates are TOO high.
I would recommend this for the hobbyist that needs a general idea of phosphates...if you need very clear accurate results, don't buy this test.Hide
