Everyone does not have the acrylic skills to make all that fancy acrylic stuff, so this is an easy Calcium reactor that almost anyone can do. It incorporates all of the high end designs.

I have rated this one for around a 180gallon tank.

Materials list.

2ft of 3.5"OD acrylic

3" PVC knock out closet flange
3"to 1/2" bushing

3" PVC union

(2) 1/2" 90 degree street EL
1/2" PVC threaded T
(5) 1" of 1/2" PVC pipe
1/2" PVC cross
(3) 1/2" PVC threaded coupler
(2)1/2" MNPT to 1/2"straight hose barb
1/2" MNPT to 1/4" straight hose barb
(2)1/2" MNPT to 1/2" 90 degree el hose barb
1/2" FNPT to 1/2" 90 degree el hose barb
(2)3.25" acrylic circle
(2)3.25" fiberglass window screen.

10 lbs #5 tideline crushed coral from petco
Mag 3 pump
CO2 equipment
total of all PVC and hose barbs $22 (includes cement)
Acrylic tube $14

This incorporates a re-circ loops that goes from bottom to top, with all the excess CO2 collecting at the top of the reactor and being sucked back into the reactor through the intake. With this kind of re-circl loop, the media will not get compacted and you should be able to run it practically out of media! Additionally, it is very easy to build. I build similar ones out of acrylic, but they are obviously more work. Thus if your stoney reef is like my stoney reef, where it is about how beautiful the tank is and the equipment is functional, not neccessarily beautiful, then here is a simple cost effective calcium reactor!

put a fluval foam and a acrylic backing disk on top of the media so it does not get sucked into the pump in a reverse flow situation!

I cut a two inch disk of fluval foam like is normally used for reactors, and shoved it into the Union tight against the 2" to 1/2" reducting bushing. VOILA! Working the way it is supposed to!
