I dont have a water softener, that is straight out of the tap. I also don't have any other ingredients and no access to them for awhile. I ordered the ingredients for those three beers right before the virus fiasco and now can't get water. If I have to I just wont brew again until water is available. I never have this much free time so I was hoping to make something but dont want to make something that isnt correct.
Your water is similar to mine. While this isn't a direct answer to your question, perhaps it's time to consider a Reverse Osmosis system. If you brew often, you can pay that back in pretty quick order. There are advantages:
1. You have it when you need it.
2. It's cheaper than store-bought.
3. No schlepping water.
4. RO water can be used in appliances like coffee makers--no scale buildup! I have a Keurig at work, have fed it with RO water for 2 years now, and never have I had to clean it.
5. If you keep the jugs that held distilledwater, you can refill them with RO water and have even more stored up. Don't use milk jugs--they can't be fully cleaned.
Disadvantages:
1. Takes time to make RO water, several hours depending on the rating of the particular unit.
2. You need a way to store the water, or you have to set it up to fill your kettle, if space and circumstances allow.
3. You may need to do some special plumbing for it to work, though that's a maybe. You can feed such a system off a normal faucet if it accepts a garden-hose adapter. Or off an outside hose bib, feeding the unit with a potable water hose (the white ones people use when they connect their RVs).
4. You have to pay up front.
A few pics are attached. This is not the only way to do this. Some people have a system that has a small tank under their sink so they can get a couple gallons at a time, but you need more than that.
I worked with Russ from Buckeye Hydro, because I was sure of getting exactly what I needed. You can find cheaper systems but then...the support is what it is.
Mine cost, in today's money, probably $170. I bought a Total Dissolved Solids meter to check the output, too. I was paying something like 80 cents a gallon for RO water from Wal-Mart (no, they had no bulk water system for me to use). So if I needed 7 gallons, it was $5.60 each time to get water, plus the time and gasoline cost of getting it. I only had to use my system about 31 times to recover the cost of the system. I'm up to batch 82 on the system, so you can see that I'm now making a "profit" on it.
I originally attached mine to the wall above my garage sink; I could also have attached it to a wooden "caddie" where I could have moved it to storage in between uses. I wanted it to be portable in case the garage temps dropped below freezing, but as it turns out, I've never had to move it.
I originally fed it using the faucet on the sink. I've since mounted it more or less permanently under the sink, and had a dedicated line to feed it. (Turns out it works somewhat better using softened water, so if you have it, feed it softened water).
I deposit the RO water in a 7-gallon Aquatainer, and from that, I also fill jugs so that at any time, I have about 22 gallons of RO water available. Some of the jugs go to my office for my Keurig, the rest are there in case I do a double-batch and just as a backup supply.
So, factor all that in, see what else might move you in one direction or another.
