Hang On Calcium Reactor

Small Calcium Reactor

A friend has asked me to build a reacotor. So we worked out the idea for a hang on unit. It will be a single chamber unit with a small pump for recirculation, something like a Maxi 1200 or a Mini 600.
I have just started the project and this is what it looks like so far.

The first pic has the freshly cut tube. Next to the tube is the remaining piece that I cut a section out so it can be fit in the tall tube. The little white disk will be the media plate. I still need to cut the holes in it. The tube is 3 inch O.D. and 2.75 inch I.D

Assembled

The flange and top have been drilled and tapped for 1/4X 20 screws. 8 of them will fasten to the flange.

The flange setting up in Weldon 14.

This is a pic of the tube sitting on the bottom plate. I do not know what this plate will look like when finished. I need the pump to fit and do the final cut.

The routed the flange.

This is the plate that the media will sit on. It is easy to make but takes a long time to drill and clean each hole. I first traced the out side edge of the round acrylic onto a piece of paper. I then find the center and set lines at the diameter, 90, 45, and 22.5 degrees. I then used a compass to set the smaller rings, seen in the pics below. Where each line crossed another that was a drilling point, except the inner most ring, it was drilled at every other line. I used rubber cement to fasten the paper to the acrylic and drilled away.

I had a scrap of material that I thought would do the job for the hanger. It will be mounted right under the top flange. It will also use two of the lid screws but, will not depend on them for support. It will be heated and bent at the end; this will be the part that will hang on the top rim of the tank.
