Hi,
I'm new to brewing,
I have a couple questions.
Do I need a ph stabilizer, and if so what part of the brewing process do I add it? Do I add it at the same time as I am building the water profile from distilled water?
Are there any recipes for hazy ipa that cover every little step including building water profile?
Thanks for reading
Hi Rfox,
Welcome to the forum and congratulations on starting brewing. I hope you find it a rewarding hobby.
In general recipes tend to be a summary of the information a brewer needs to make a particular beer, so they usually don't go into every little step. For most brewers this would present a lot of unnecessary procedural information they would need to wade through to extract the info they need to make the beer on their own particular equipment and using their own particular methods.
If you're after a recipe and the exact procedure used to make that recipe so you can follow along brewing the same way with the intention of getting the same result, then I suggest looking for a video, perhaps of someones brewday. Preferably someone well regarded, like good reputable brewing shops, know good brewers - John Palmer of How to Brew Fame, Brew Your Own (BYO) magazine, etc.
A pH stabilizer is intended to be used in the mashing process to help keep the pH of the mash in a suitable range for the enzymes in the mash to work best at converting starches with the grain into sugars the yeast can ferment. If would be either added directly to the mash or to the water used in the mash. Most brewers don't use it, preferring to treat their mash water with discrete chemical stabilizers, like for example calcium ions, rather than the more generic approach of a pH stabilizer. Typically modern recipes include these discrete chemicals as part of the recipe.
Water profiles achieve two *main* objectives. The first is to help the pH be in a suitable range, rough 5.2 to 5.6, depending on the beer. The second is simply flavor, just like adding salt to your food. Discrete chemical additions allow the brewer a chance to adjust the flavor of the beer. Just like salt on food, flavor preferences vary. These days, good recipes usually also tell you about the water treatments needed to help the pH stay in range and to achieve the flavor the recipe's author is targeting. Keeping the pH in range is quite straight forward once you know the grains but the choice of chemicals used for the flavor is very much up for debate thought there are some broad guiding principles. As an example, in the Brew Your Own (BYO) article:
Brew Your Own - New England IPA
It's says:
This recipe uses reverse osmosis (RO) water. Add 1⁄4 tsp 10% phosphoric acid per 5 gallons
(19 L) of brewing water, or until water measures pH 5.5 at room temperature. Add 3⁄4 tsp.
calcium chloride (CaCl2) and 1⁄4 tsp. calcium sulfate (CaSO4) to the mash.
Note that "brewing water" here refers to the mash water and the sparge water.
These three additions are quite common for pale beers with the ratio and amounts of calcium chloride and calcium sulfate varying depending on the flavor profile the author is targeting.
To get started on Water treatment/profiles, as YAPN already suggested, I can also recommend John Palmer's "How to Brew", though I think he goes on too much about Residual Alkalinity which, in practice, you can skip. Everything I've written above and more is well covered by Palmer.
Another great Water resource and excellent tool is the spreadsheet by Martin Brungard, a professional brewing water consultant. His website, and the spreadsheet, have lots of info and dozens of prebuilt water profiles:

A question for you.
You mentioned you're a new brewer, very roughly what sort, and how many beers have you made so far and on what sort of equipment?
Cheers!
