homemade Kalk/CA reactors. how did you make them?

[The Reefer91]

i am considering making a homemade kalk or Calcium reactor. i am wondering if i can make one cheap? how much did it cost you? could i see yours?

A lot depends on the materials & the design. Generally under a $100 for a cast CA reactor. We did a kalk reactor party & the cost was $40 but that was with some donated materials & extruded stuff.

Here's a copy of a famous design, not nearly the same quality but it's functional:

I made a kalk reactor pretty cheaply. I don't have an exact cost but I bet is was about $40 including the mixing pump.

I think I CA reactor would be more expensive because of the CO2 bottle and regulator.

Here is a pic of mine. I borrowed very heavily from others on RC.
