Calcium reactors

[trilinearmipmap]

I recommend the Austin Oceans calcium reactor.

It is available from the U.S. however our dollar is worth more now.

The advantages of this reactor are:

Dual chamber upflow design
CO2 scavenging
Built-in CO2 bubble counter
Built-in flow meter
Feed pump not required
No connections through the acrylic tubing, only through the ends
Built-in port for pH monitor

I bought one a few months ago, it is easy to use.
