Distilled or Glycol for crystal packs
Here is another newbie question. I don't think I have seen an answer (let alone this specific question) regarding if it may be better to use distilled water or the glycol solution in the crystal packs. I have seen the manufacturer say to use their brand "solution". This solution usually is a 70% (or whatever amount) of glycol. Then sometimes I see postings that say to use distilled water. What is the consensus? Thanks.
