DIY CO2 scrubber?

[Arkonen]

Has anyone here built a DIY CO2 scrubber to plumb in-line to their skimmer intake?  What materials did you use to build the container?  Where did you get your soda lime?  Did you have any issues/pH spikes?

Why not just buy one from BRS, for the price I don't think DIY would be worth it.

Soda lime here (half the price of BRS) http://www.shopmedvet.com/product/soda-lime-3-lb-bag/jorgensen-products-anesthesia-products

 

I built a diy one but I only had to buy the round acrylic tubing from McMaster-Carr, the other acrylic and fittings were drop from work.

 

In the end I decided that the perceived benefits were not worth the added time and media costs and stopped using it.  I used it for a few months and while it did raise pH on average about .2, nothing better happened in the tank as a result.

Here are some pics of it, holding 3 pounds of soda lime.

I really like that canister style.  Did you CNC that yourself or buy it somewhere?

I used a CNC laser cutter at work.

If you have an extra reactor lying around get a CDX adapter and turn the reactor into a scrubber.

Petsmart uses a big tower filled with bioballs and water trickling through them back into the sump as a degasser. Works fine on a system that holds thousands of fish at times.

No need for chemicals.
