I have been looking into how a calcium reactor is built and was wondering if the aspects which I have taken into consideration are correct.

First of all the Ca reactor should have the water enter from the top and exit through the bottom to increase contact time and at a low flow rate.

Second the Co2 which enters through the bubble counter should enter through the top.

Third there should be some type of mechanism in place so a sample of the water in the Reactor chamber can be taken to measure the ph.

Fourth there should be plenty of room for a decent amount of media.

I guess this would be for a single pass system but, from what I have read there doesn't seem to be anything stating that the recirculating reactors perform better.

I am posting this because I have searched on Wetweb and some other sites but, have seen posting and faq's on the process which the Ca reactors work but, not on the ideal or necessary aspects which a good Ca reactor needs to work.
