From what I've read, I've heard they don't need to be cleaned at all from the force/current of the water being drawn thru them. Then again, only from what I've read.

Pricing runs around $40-$100/usd.

thats not going to stop them from getting plugged up with minni stomatella sp. shells :rolleyes:

Steve

Steve is correct. With my old skimmer (venturi) It was running a 1" mazzi ventuti which I still have. It would get plugged 2 to 3 times a year with a stomatella shell. the injector itself worked very well and produced very fine bubbles.

one cool feature of the mazzi I like is that it has a spring loaded rubber ball on the air intake so it doensn't matter where you have the unit. What I mean by this is if you shut down the skimmer you don't get water flowing out the air intake.

Did you have to clean it at all (other than taking the shell out?).

Ahhh interesting. I was wondering why there was that square section where the air comes in.

From what I am hearing, if you match the injector to a proper pump you can save big time on power, as the becketts need a more powerful pump. Since there are injectors with multiple flow rates for a given size i.e. 3/4" of Inlet and outlet, I beleive you can choose the appropriate one for your skimmer baased on the dimensions of your reaction chamber.

I think they have also appointed a rep just for skimmers, who can help you determine the appropriate injector and pump.

Did someone say spring loaded, is there a corrosion problem then?

No cleaning other than taking the shell out.

Venkiw. No corrosion yet on the spring after 1.5 years use or so.
