Calcium reactor

Mike220 · May 18, 2017

Hello guys

I have 250 net gallons and one GEO 618 calcium reactor, but can't keep up my ALK.
plan to buy another GEO 618 used from my friend. But how do connect together or have to run one by one.
1 one now is connect with apex.
Anyone using 2 calcium reactor, not a 2nd chamber.

Thank for your help

What are you using for Media?

Also what's the ph in the reactor? And have you tried adjusting the effluent to increase flow?

Apex control 6.6 is on and 6.45 off
Yes, did more effluent flow. Around 40ml/Min

How much does your alk drop daily? I recommend increasing your effluent by another 10-20ml/minute

I have found in usage of ARM that it tends to deliver a lot of Cal but not much Alk. When I ran ARM I was getting around 8 to 9 and my Cal was around 475-480 and I have switched to Reborn everything the same drip, ph setting, just changed out Media and when checked after a few days maybe a week Cal was 450 but Alk. was 10-11 and I have found the Corals seem to lie it better.
It maybe worth a try and switch out the Media.
