Pure Leaf Tea bottle Co2 scrubber

[TMC]

I've read through several of the DYI Co2 scrubbers and took ideas and concepts from them all and built mine so I figured I would go ahead and post it.
I used a 2 liter Pure Leaf Tea bottle as the container


Here is all of the components
3/8 OD clear PVC tube that I threaded 5/6-24 on one end to screw into hose barb
3/16 hose barb with 1/4 MNPT threads to screw into cap that I tapped 5/16-24 to receive tube, I cut all but the last barb off.
3/16 hose barb with 1/8 MNPT threads again cut all but the last barb off


I drilled a 1/2 hole in the cap to screw the output barb into and a 3/8 hole in the top side for the intake barb to screw into I used a barb here just in case i need to boost flow with a little air pressure



And here it is all loaded up and ready to go


Hope this helps somebody as much as all the others has helped me

Have you hooked this up and what impact your pH

I have not yet going to in just a bit. I will post if there was any impact at all in the morning.

I think you would at a minimum need to put a moisture catcher inline in front of this. It still might get the media wet at the bottom. If you could suspend the media off the bottom 1" I think that would solve a future problem.

*****Might be fine if you are NOT recirculating

Thanks I will keep an eye on that, not recirculating just going into skimmer air port

PH has been running between 8 and 8.2 consistently this morning it is 8.4 so I do believe it is working I will keep checking everyday at the same time for the next week and see if it stays consistent.

It is definitely absorbing Co2

Update: PH stayed at 8.4 for about a week and then started climbing until checker gave me a flashing 8.6 so started only hooking it up at night when lights were off same problem so quit using it only to realize that I had a bad reagent batch from Hanna they sent a replacement and PH was running at 7.8-7.9 so hooked scrubber back up and have been at 8.3 consistently everyday for two weeks now.
