They all effect the mix. I used to start by adding calmag to bring the ppm's up to 250.

Looking very good and I can see alot of hard work. Can't wait to see the turn out.

I was suppose to go to Michigan and help a friend build a room just about like yours but the engine in my van cracked a block or something and I have oil in the water. Trying to get my MGB going but that's a long trip and I can't carry many tools. LOL

Maybe when I pull the engine I'll clean it up and do a grow out of the cylinders. LOL
