Red sea vs Hannah Checker Phosphate

There should be a standard solution for that check available, no? Maybe you could use that to verify if the checker is operating properly

Yeah that'll have been really helpful but it didn't come with anything of that sort

Wow thanks.

Wow thanks.

No problem.

You do have the ULR correct? Just make sure you get the one to match your checker model

Yeah I found one, already purchased. Thank you so much, that's so helpful.

The only problem I have with Hanna's standards is that they usually are pretty far outside the range we are usually checking for. Point in case is this one which is 100 ppb which is far outside where we usually expect our tanks to be (~10-25).
