You've got really hard water. You'd be a good candidate for dilution with distilled, or RO water. I'd try brewing with filtered/RO water first before I started looking at my equipment.

I used to brew with my RO, but since going to AG a couple years ago, I thought I'd need some minerals. I usually brew darker beers/ Should I do like a 1:1 dilution or even 2:1 RO?

I'd guess that your problem probably is with the water. Were I confronted with this water I would install an RO unit and brew with a blend of that with some of the tap water. Nine parts RO and 1 part tap would give you pretty reasonable numbers for all the ions.

I do have an RO system already....9:1?! Wow...wouldn't that be each of my numbers / 9? That seems like not enough.....

Maybe I should know what I'm shooting for here....is there a pretty neutral profile to shoot for before additions? guidance?

Seems like 2.5 or 3:1 might be about right for UK beers.....

water profile should be recipe specific, there is no one water profile that will suit every style. I'd start by listening to the 4 water episodes of brew strong, and reading the water chemistry chapter in how to brew.

OK, I will do that.

What happens if I want to keep my calcium, but reduce my Mag (like dublin)? Is there a way?

dilute with distilled to the desired mg levels and add back chalk, gypsum, or calcium chloride (depending on sulfate levels and desired residual alkalinity) to reach the desired ca level.

I'd also be concerned with the Na levels in your water. That seems like a lot of sodium for most styles.

Wow, you're right. I was looking at London because I just made an ESB, but London seems to have exceptionally high Na levels. I think the right way to go is probably just use RO and add salts as needed per brew.

Are you making sure that your mash ph is in check? With that high of bicarbonates you will easily over shoot your ph, causing tannins to be extracted.
