Co2 reactors is this meant to happen??

Hi,
i have just setup my pres Co2 on my tank, the reactor i use is hooked up to the out take pipe on the cannister. When the co2 is going in its pushing tiny bubbles out of the spray bar in the tank. Is this what its meant to do. Is this reactor disolving the co2 propley. Then the tiny bubbles release to the top of the tank and burst. Then it makes it noises in the reactor like a burp.

2 things come to mind that can cause this:
a) your filter is too strong, and the bubbles are just being forced out of the reactor.
b) the water you are feeding into the reactor is coming in from the bottom, and out through the top, in that way the bubbles just rise, and spit out. The bubbles should be rising against the flow of water to dissolve it.

That's what it sound like to me too. If you have the outflow from your filter go in the top of the reactor and out the bottom then the bubbles won't generally be able to make it to the tank.

And if it's newly set up there is air trapped in it that is escaping. It can take a couple of days to completely purge a new reactor. And the bio-balls actually make it worse.

Assuming that it is connected with the flow going from top to bottom, you might try tipping it over so that any trapped air can exit it. I left slack in my return lines for this very reason. Every time I clean my canister filter air gets trapped in the reactor, a quick flip clears it out.

This is the design from my reactor. I modifed the design a little bit. I decided to leave the cap on the end of the bottle and drill a small hole in the cap for the bubbles to escape out of.



I'm 100% happy with my reactor! The bubbles come out so tiny you can hardly see them and the plants pearl like crazy.My CO2 on the other hand.........::cough cough::

the outflow is hooked up to the bottom and comes out the top of the ovc pipe and the co2 goes in at the bottom. Its working fine now. I pushed the spray bar down in the tank and pointed it towards the sand. I have only got minimal bibbles now which is good. The ph is set at 6.8 which is giving me 37ppm of co2. cheers

Well sounds like you have more of an injector than a reactor, but if It's working for you, great.
If you ever want to get rid of the bubbles, flip it, and inject the co2 about 1/3 - 1/2 of the way down (If you can).
