Thanks Foppa. I had been using lactic acid in the mash water prior to switching to 5.2. I guess there are many ways to skin this cat. I think I will omit the adjustments to the sparge water for now while using the 5.2.

No problem KD. Let me know how the 5.2 is going. Maybe I will switch if you are having luck with it. Are you taking readings with a ph meter?

You guys should check your PH of the mash using PH test strips (just the liquid). Then you will know if you need the stabilizer at all. It's crazy to put it in if not needed. I have the test strips and the Star Chemicals stabilizer and do not need it as my PH has been fine.

I start with RO water and build it up. I do trust in chemistry, but I like insurance.

I have a digital ph meeter and take lots of readings. The water ph around here is high.

Your grain affects the PH so add strike water and stabilize the temp and then stir again just before testing the PH. If it is still high then add the stabilizer and stir well. You do not need stabilizer in the sparge water because the conversion was already completed in the mash tun. You are now just rinsing the sugar from the grain when sparging and there is no point to using stabilizer in the sparge.

We makeour own. There are portable models that deliver about 75-90 gallons per day for about $200.00. Faster models are very expensive.
