SOS! How to test pH in Hyposalinity?

[Depth]

MR Knowledgeable Folk!

I wonder if anyone has encountered the following problem:

I am treating for Ich in my QT, using Hyposalinity. I already lowered SG to the possible minimum (SG= 1.009).
My water now is, so to say, neither salty nor fresh. And I feel that my Saltwater test kit for pH is no longer accurate!! :irked:
Knowing how important it is to keep the pH consistent during the Hyposalinity treatment, what do I use to test it with?

Any timely help will be deeply apreciated.

can you borrow a ph meter? They'll measure the ph regardless of salinity.

And I think your saltwater test kit will give you a good idea. It might not be exactly accurate, but it should be close.
