Connecting CO2 scrubber to skimmer

[dbleoh7]

I bought the BulkReefSupply CO2 scrubber to attach to my Bubble Magus skimmer but the tubing is too big to attach to the intake of the skimmer without a big leak. Pic below. How are you all connecting it?

You should be able connect it directly without using the muffler

SO you're saying disconnect the hose going into the muffler and connect it to the hose going into the Co2 Scrubber?

Guys, excuse me for asking here. What is a CO2 scrubber? Is it a special scrubber? Where can I read about it? I can't find any information on it.

It's a device filled with CO2 absorbing media, that removes CO2 from the air that you're feeding to the skimmer.

It is used if the air in the room contains a high level of CO2 which causes tank pH to drop. By removing the CO2 you raise the pH in the tank which increases coral growth.

I've attached a photo of what mine looks like below.
It's the cannister on the bottom.

The clear tube is the intake which is where air from the room gets sucked in.
The brown tube has the air with CO2 removed.

In my case that feeds into an Ozone generator, and the output of the Ozone generator feeds into the skimmer air inlet.

It still doesn't have a tight fit... Any ideas on how to get it to fit? I'm assuming Home Depot or something would have an adapter...?

Its a unit that looks like a reacor and uses special media for absorption.
See you tube videos to see one in action

Remove the silencer line and attach the tube running from the scrubber directly to the skimmer venturi

The tubing is too big to fit on where the silencer line was(pic)... Would it be ok to just put the tubing into the big Venturi hole like in the picture?

That's not the water inlet, right?

You can't plug the water inlet.

Must be. I experimented with putting the CO2 scrubber line in there and it did not work. Go figure haha.

Since the tubing doesn't fit, I ended up just taking the two tubings (tubing from CO2 scrubber and tubing from smaller air Venturi line) and putting the smaller one pretty deep into the larger one. It's a pretty tight fit, but definitely not air tight, so I put joining area under water so it's forced to pull air from the CO2 scrubber. It made sense to me so it should work right?

Might be able to find a double ended hose barb at menards or online that reduces the line from the scrubber to the size you need for the venturi. This is going to be your best option to assure no leaks.

Something like this. I’m not sure what size fits onto your venturi. I was lucky and my reef octo venturi was 3/8 like the barb on the scrubber!

Just curious do you monitor the O3? Or do it old school with the sniff test?

The ozone is controlled by an ORP probe. It only runs at night, and turns off if the ORP goes over 375.

If I can smell it, time to change the carbon.
