CA reactor with no re-cir pump
 

Was looking for some tubing and got this DIY CA Reactor second chamber from lookdown.

Plan is to add the recir pump but as was going back and forth on the best way to mount, just hooked up the chamber with the existing fittings.

I'll still be mounting the Mag3 (hang it high with uni-seals) to save a little CO2 but if I didn't already have it, probably not worth buying a pump. Reactor has only been up a week but is keeping my Ca ~400ppm and Alk ~11dKH. This is on a moderately stocked (SPS) 145g with 40bpm (which I'll be lowering).

Unit is fed off the return pump and water and CO2 enters at the bottom, return is from a fitting on the top.
