Red Sea phosphate test problem

[SlimJim009]

When I go to test my phosphate (low range), I get .04. When I check it with high range, it should read 0 but instead it read .34 (aka .02). Am I doing something wrong? Im thinking the rodi water I use is messing it up somehow but idk. Ang help would amazing, thanks.

So you use 17ml of tank water and get .04?

Yes

 

[Daddy-o]

Why do high range?

 

[Hincapiej4]

For high range you're using 1 ml of tank and the rest rodi right?

 

[Hincapiej4]

If this is true, then your test should come back clear to confirm you're under 1ppm phos

 

[SlimJim009]

For high range you're using 1 ml of tank and the rest rodi right?

Thats correct

 

[SlimJim009]

Thats correct

Thats why I think my rodi water is messed up somehow

Then you have phos in your rodi. How old is the test?

I dont quite get the question.

 

[Daddy-o]

Use the low unless you are too dark then use high range. Check your straight ro with low also.

Will it work with only freshwater?

 

[Hincapiej4]

Will it work with only freshwater?

Yes. And I'm saying you might have phos in your rodi and asking how old is the test

It expires in 2 years

 

[Hincapiej4]

Ok so if the test expires in two years, then you might have phos in your rodi
