I acknowledge that this is a small issue so don't jump all over me for focusing on such a slight detail.
My question is in regards to whether you fill your bong with hard or softened water. We have both, you are supposed to drink the hard water, but I fill my bong with the softened water. I haven't noticed any difference though.
Would this change anything at all or could this just be a pointless thread discussing various types of water? ;)
