Hong,

Sorry but for some reason this forum will not let me PM it just freezes my computer when I hit send I used Wirsbo tubing in my pond, you would want to use the HePex oxygen barrier tubing and it should be fine for the fish they use the same type of product for drinking water, for a boiler I would look at the Buderus GB142 series

Don't know what is actually wrong with the private messaging but usually it will work if you delete whatever the person wrote when replying to them. The shorter the better as well.
