You've got to have a check valve or as the CO2 in the line dissolves, the water will always creep up into your washer bottle. Plastic check valves are pretty cheap in the local tropical fish stores in the USA. You need a check valve that has a low forward cracking pressure. Get a plastic, stainless steel or brass valve with 1 psi or lower cracking pressure if you can.

Never argue with a fool. Onlookers often can't tell the difference.
Growing older is mandatory, growing up is optional.
My advice is free and worth every penny.

I can blow past the check valve but I am not sure if the little yeast can.
Availability is a huge issue here, well except for chain restaurants. Local fish stores here do not know or have anything. This is the only check valve I found. I'll look harder.
Thank you

Your yeast will generate plenty of pressure. No worries there. It has blown up pop bottles and other strong sealed containers. Sounds like you should try your brass valve anyway. If you can blow through it in only one direction, make sure the forward direction is towards the reactor, not the yeast. Also place it after the gas washing bottle to keep the gunk out of it.

The orientation is correct. It is placed after the gas separator before the input at the reactor.
I can blow past the valve it at half effort. If the yeast can blow up soda bottles they certainly should work. I'll try adding silicone to the air holes I created.
Tomorrow Ill look for a regulator and a CO2 cansiter at the everything-flea-market.
Thank you very much for your help and prompt replies.

For future reference, Watts 7/8" ID washer/dishwasher hose fits very snugly in GE (and I believe Whirlpool) filters. No need for glue.

Finally hooked up my 20" version this past weekend ...this thing is way better than the aquariumplants.com version I originally had...you dont need that internal pump they squeeze in there..its complete nonsense...in my unit the CO2 completely dissolves and saturates the water in the 20" tube...I can pump all the CO2 I want in there...
I'll try & post some pics before the week is over...

What size pump or filter is being use with this? Did you get the 1" port or the 3/4" port?

I'm thinking I'd better snag one of those on E-bay for my future large tank. Show us some pictures of your Cerges' set up with that bad boy.

I know it was discussed earlier the merits of this for a 6g, but what about a 20g long? Filter is a Eheim 2215 (163 gph rating). I know it's probably overkill but I love DIY and as long as my filter will put out enough flow for it to work I'd build one

Has anyone in uk built one of these from these instructions? Just wondering if someone knew of a readily available filter as the omni ob1 is only available from USA from what I have found

Now a 20gal sounds a lot better. I think it will work fine and Cerges reactor barely cuts flow down, least not enough to notice, just as long as its free from media. Good luck!

I'm running my reactor in series with a Marineland Magnum 350 and I don't have any flow restriction or filtration issues in my 45 gal tank.

You could put a school bus in line with a Magnum 350 and not notice any restriction in flow Those things are pretty much tanks! They might not have the bells and whistles of "new" canisters, but I've had two running 24/7 for about 5+ years now with zero problems.
