I don't know about simplified, saved or in any other way helped out my aquarium keeping, but I LOVE my inline CO2 diffusor. I installed it last weekend on my 75 gal tank. My bps is right around 1 and I have a bazillion micro bubbles flowing around the tank.

I got the 17mm due to my hose size. These things are amazing!!
