Product details

The LaMotte Insta-TEST PRO low range phosphate test strips read pool phosphate down to the parts per billion levels that matter, with 50 strips to a bottle.

How the test works

These are reagent delivery strips, which means the chemistry is carried on the strip itself. Dip one, wait fifteen seconds and read the color against the scale. There are no separate reagent bottles, droppers or counted drops involved.

The scale

Results are compared against seven steps: 0, 100, 200, 300, 500, 1000 and 2500 ppb. That low range resolution is the point, because pool phosphate becomes a problem well before a coarse test would register it.

Why it belongs in the test kit

Phosphate is food for algae. Chlorine can be at target and the water can still turn if phosphate is high and conditions are right. Testing it turns a phosphate remover into a planned dose rather than a reaction to green water.

Questions and answers

What people ask about this product, answered by our pool techs.

What phosphate levels does it read?
The scale runs 0, 100, 200, 300, 500, 1000 and 2500 ppb.
How long does a test take?
Fifteen seconds. Dip the strip and read it against the scale.
How many strips are in a bottle?
50 strips per bottle.
Why test phosphate at all?
Phosphate is a nutrient that algae feed on. Knowing the level tells you whether a phosphate remover is worth dosing before a bloom takes hold, rather than reacting after the water turns.
