hi Gomer

1. yes it is vertically positioned
2. CO2 is on the top section
3. flow goes from top to bottom
4. i cant be sure cause the tube is grey PVC.

any advice?

There is a good possibility that the air bubbles are trapped O2/N2. While you have flow, turn the reactor upside down. You will probably get a big burp. After the reactor is emptied of gasses, you should have no more problems

Tony, how often do you find your reactors needing a "burp?"

I don't think there can possibly be enough O2/N2 accumulation as to cause a 24" reactor at 1 bubble CO2 per second to constantly burp tiny bubbles. While it is normal for a reactor to burp bubbles during the first few days of operation, if it continues to burp tiny bubbles then your flow rate is stronger than the natural buoyancy of the CO2 bubbles, thus flushing them out of the reactor. Two things you can do to remedy this: (1) lower flow rate and/or (2) put more bio-balls, bio-rings, etc. The former is usually not very negotiable but it is pretty easy to stuff the reactor with more bio-balls/rings/stars/etc., even when it has already been sealed. Simply hack-saw the PVC tube in half, stuff it, and join the two pieces back together with an appropriately-sized PVC coupling. These obstructions slow down flow rate and trap gas bubbles; thereby allowing their dissolution before being blasted into your tank.

When I open up my canister and re-prime after cleaning, I introduce air. THis is the only time that I may have burping. After purged, I never have any burping issues. I run pressurized CO2.

Thanks for the response, Tony. Now that you mention it, I had not noticed any gas build-up prior to opening my canister filter for cleaning. Thanks for the tip.

Gomer,
any thoughts doing an inline reactor of this type with a Zoomed 501 filter? WOuld you scale it down considering the lower flow?

Gomer · 03-22-2005, 07:12 AM

I see no reason why you couldnt scale it down. I of course have no plans for that LOL

I'm planning on purchasing an Ehiem 2213, would this reactor be fitting for this filter and a 29 gallon tank?

Looks really spiffy... Hehe...

I've used this reactor with a 29,30 and 40g powered by either a Filstar XP1 or XP2 ..not a single issue.
