Cerges reactor - 10" or 20" housing?

Hi guys,

Two questions actually:

1) I'm about to order a housing to build the cerges reactor. What is the use of the pressure release button?

2) Should I get the 10" housing or 20" housing? There's a significant difference in price but my criteria is that there are no microbubbles being injected into the tank...Is 10" sufficient? Perhaps with some kind of media/sponge/ceramic diffuser?
Thanks

Maybe you could tell us a bit more about the tank and what will be pushing water through the reactor?

The pressure release button is for when you have to open the housing for filter changes during normal household use. Mine does not have one. I'd imagine you could use it to burp the air out as your canister fills it. The longer the housing, the less chance you'll have bubbles. Yes I would fill it with something like sponge. I put a big old sponge filter in mine. Anything you add will also double as increased biological filtration anyhow, but may further reduce flow. As for micro bubbles, I couldn't tell you yet as my substrate is still releasing air, this is a new tank.

Okay thanks for the input guys.

My tank's 50 gallon with 2 x Eheim 2217...One will be used for this reactor. Heavily planted high-tech.

I have a rio 2500 pump pushing uncountable bubbles through an empty 20" housing. Accounting for head loss the pump is probably pushing 300-400gph. I do see a few bubbles through 6' of water I think are from the Cerges but they aren't a bother. If you have the room and the price is about the same I'd go with the taller unit.

+1 for a 20" reactor. IME the griggs-style works a little better though.

Pressure release button is useless.

I found the pressure release button is handy for bleeding out the air when you connect it all up.
