Review on Aquarium Tubing High Pressurized 6X4Mm by Pamela Bellancoutt

I bought this inline CO2 diffuser after reading many positive reviews on Revain Prime and several aquarium blogs. I bought the 16-22mm version which I use with OASE hoses for a 5/8" ID canister. The 5/8" ID tube fits perfectly into the diffuser. I put the 5/8" hose in hot water for 15 seconds to make it fit over the two diffuser ports. But I think I could do without it wear.As other reviews have mentioned, two gray grub screws are included.The bottom nuts do NOT even fit the pipe on the diffuser so I used #6 stainless steel clamps instead which I prefer anyway.Prime which worked great. I also heated it because this CO2 tube is VERY stiff just like the reverse osmosis tube.I use a CO2 supply pressure of around 40psi but I'm sure it will work fine with less pressure.The diffuser produces very small ones Bubbles that are barely visible at the outlet of my aquarium atomizer, which is MUCH better than the ceramic CO2 aquarium diffuser I've used before.This makes for a MUCH better distribution of CO2 throughout the tank.And no sudsy he mush on the surface! All my plants are thriving and growing like crazy. It's made of metal and plastic with a VERY solid construction. I give this slotted diffuser my highest recommendation...it's worth every penny.
