I think it's unanimous that a cerges reactor would be ridiculous on a 4 gallon tank. Hey, knock yourself (and probably everything else in the tank) out

you can use ZooMed Nano filters on nano tanks, but am not sure how this will work with this reactor or might not even work at all.
Hmm well I wanted to use the Cerges reactor to avoid putting a diffusor in the tank. I've also read that the ZooMed and Finnex nano filters don't provide enough flow to be placed under the aquarium (let alone enough flow for an in-line diffusor). Maybe I'll make a smaller inline PVC diffusor instead of the Cerges. Thanks for the input.

UPDATE

i have tested this reactor with whatever method i could think of.

1st method: just insert the pvc tube and left the inch from the bottom so water could enter. this wasnt best way to work with such a high flow of my filter 525gph, which was the main reason the bubbles were escaping.

2nd method: put the pvc pipe all the way to the bottom and drilled some holes and results were same as 1st method.

3rd method: sponge or pot scrubber on the bottom, this method works the best and less bubbles coming out now. but still misty type bubbles are coming out, i think am going to remedy this and play around with the setting.

4th method: Get 20" long filter then use 1st method

i was thinking about it, but not sure where i can find it cheaper and i think it might be smaller in diamter.

EDIT: the cheapest i found was $42 shipped. i think i might go with this one.

Give me half an hour and I'll get under there and take a shot of it next to a GE Smart Filter. It looks a little narrower but I think that's an optical illusion. I'm running about 4-5 bps with a Mag-5 pushing it into an L shaped spraybar. All 3/4". No bubbles in tank and a green/yellow checker.

When you look into the 10" can and see the area outside of where the downtube is, it doesn't look any bigger than the 20"er - I was concerned about that too when I took it out of the box but in reality, the 20"er is actually slightly larger internal diameter. Not a lot mind you, but rest assured it's not less.

Ok, Hope these help you make your decision. Good luck! BTW I liked those guys where I bought it from. I called them and chatted with a nice lady who answered a few questions. Seemed legit.

Also, those are water spots on the OUTSIDE of the clear housing. I just noticed those! At first I thought "hey what's that CO2 doing stuck there" then realized what it was....

Cheers

m00se hows it working with the FX5 filter , Do you get a lot of bubbles blown into the tank?
I'm planning on a setup like yours for my Eheim 2262 filter for my 110g tank.

inkslinger, I'm running a Danner Mag-5 into it then to an L-shaped spray bar. The FX5 is separate.

how long does it take for your reactor to disolve all the left behind co2 after the co2 goes off?

so far mine took half an hour to disolve completly. if it takes more than 1 hour or so, then consider this a bad sign.

There is no leftover CO2. At 4-5 bps it's completely dissolving. I don't know what the capacity is because I'm not interested in putting my fish to sleep. There is NO gas standing around at the top of the housing. I'm also using the venturi intake that comes with the Mag-5 with the fractionator impeller. I'm using a solid impeller on it though. I don't know if that makes a difference or not. It's nowhere near maxed out as it is.
