Re: CRS alternatives
Here you can choose your strength. I went for 25%, though looking at the choices now, I'd have probably gone for the 1M, as, similar to other suppliers they don't specify whether the 25% is v/v, w/v or w/w. You know where you are with Molarity.sladeywadey wrote:Thanks for the info. Do you have a link for ordering? ThanksMillmoorRon wrote:Mine arrived yesterday!

Re: CRS alternatives
Thanks for that Dave. What's the situation with Hydrochloric? Can you get it at a decent % (or M) without having to dilute?

Re: CRS alternatives
APC do that as well, I think. Not sure about the dilutions. I bought mine from eBay and diluted myself.sladeywadey wrote:Thanks for that Dave. What's the situation with Hydrochloric? Can you get it at a decent % (or M) without having to dilute?

Re: CRS alternatives
I'm now out of sulphuric acid.
After some helpful discussion with Eric after me finding a bottle of AMS lurking in my beer fridge, I am going to trial a new water profile with just using AMS/CRS and gypsum/Cal chloride.
For anyone interested, I am brewing an APA using west coast yeast (MJ) and this is the profile I will try.

Re: CRS alternatives
That looks fine to me. If anything I might get the sparge water alk down a little, but 26 certainly isn't out of the park.sladeywadey wrote:I'm now out of sulphuric acid.

Re: CRS alternatives
Yeah, only one that stated food grade, but to be honest I'm not really bothered about that. We use them in such small quantities I don't think it matters much. Because it doesn't say food grade doesn't mean there is something awful in there - apart from acid of courseMillmoorRon wrote:When I looked I thought there was only one food grade strength?Dave S wrote:Just had a look and APC do all manner of dilution.
