I was just wondering if tubing really made that much of a difference because i can get 1/2 id tubing at cost from Rona (Canada's Home Depot) which is like pennies/foot. Where as some stores are selling tubing for like $1.50/foot. Is cheap tubing going to to anything to my water or discolor or anything? I don't plan on using any dye in it. Just distilled water and water wetter. Oh yea and can water wetter be used instead of anti-freeze?
