3/16" inner diameter tubing

[Biotech]

Can someone please tell me where I can find this size tubing. I want to improve the performance of my Euroreef CS8-2 skimmer. I read from reefcentral that increasing the nipple size to 3/16" will work, but Rona does not seem to carry this size tubing. Have not checked HD yet.
If you have some, could I buy a foot to a foot and a half from you?
Thanks

The best place to get this kind of tubing would be at Bartle
& Gibson or another plumbing specialty store. B&G is at Ft. Road and 137 ave, you could also try RSI on 111ave and 119st.
