How to raise PH of distilled water for hyposalinity?

[Zissou]

Using the hyposalinity treatment to cure ich. Lowered tank water from 1.025 to 1.020 with 3 gallons of distilled water (15 gallon tank) and will be doing a few more water changes over the next day or so to bring it down to 1.009.

I baked some baking soda, and was wondering how I go about mixing it with the distilled waterchange water. I read that the new water going in, should match the PH of the tank.

The PH of the distilled water is 5.5, the PH in the tank is about 8. Introducing the distilled water without 'treating' it will affect the tank PH, correct? So what do I do? :dunno:

I don't want to fight ich, only to kill my fish by screwing with the PH. :(

Once you add salt to the distilled water, the pH will go up. Don't worry about buffering it.

5.5? Are you sure? That seems awful acidic for distilled water.

Brian, I made a mistake reading another label online, the distilled water is 7. My mistake.

ccCapt, I won't be adding any salt to this water. It's a portion of the hyposalinity process to reduce the salt over a gradual period.

Blah, I really need to just get a ph pen. It's hard judging the colors on the test kit. :squint:

you will be fine adding the water

I agree on the judging colors. But do you really need to know the the ph closer than .1?
