hmmm, it seems that water line tubing is also much cheaper than silicon tubing, so maybe I will explore that instead - thanks for the link discussing various tubing and their PSI abilities.
I'm actually trying to run a waterline from my sink to my fish tank, because I lose 2-4 gallons per day to evaporation since I need to fan cool the waterline to keep my shrimp in the low 70's.
I also have an airline need as well, but I really don't want the solid white stuff most under sink water systems use, I want a white
frosted clear tube similar to my picture. If I end up wanting your tubing, would you be able to sell me a cut piece, or are you limited to reselling large rolls.
I can get 50' of this stuff shipped for $19 - as usual, the shipping kills the deal because they are charging for 2LBS UPS whether you buy 10' or 100'. I need to find something local, or someone willing to ship <1LB using USPS. most of the Home Depot stuff is sold for irrigation and water filters, so it's all black, solid white or clear.
