I'm looking at https://cch2o.com/ Current Culture website , great website with good choice , everything build by a professionals . I'm curious why they don't use a Venturi air injectors, but air diffusers only? I've installed 2 venturi 1/4" injectors (on a picture i think it's 1/2") with 1000gph water pump and using 2 stones , it works as it should , but do i really need it? What if i switch to current culture air pump with air diffusers, will i get same results?
