Marek and Chris, 

> I have to correct myself! After reading your post I went back to look at my notes. I started with half a liter solution and 20cc muratic acid

>> This is about a 0.75% solution, correct (muriatic acid is 37%?)?

In Italy we usually call "muriatic acid" (the old name for hydrochloric 
acid) that sold at the supermarket, which is about 10%. Funny, sometimes it 
is declared "not more than xx%". For me, also distilled water has an HCl 
content "not more than xx%"!
Is it the same also in U.S.?
