Figure around 350 for a full solenoid/ph/digital gauge. We already have the functions pretty much to have a completely integrated calcium reactor setup.


Sounds reasonable!! The regulator I got was $300 no pH control

And no digital gauge. :)

How about a continuous duty peristaltic pump? Controlled by RA, not that would be the ultimate controllable CALRx Rig.

You could add the RA dosing pump or the ATO one to the mix...

Are these continuous duty?

Anyone working on this? Would be great just to have a controllable solenoid. Big market for those and CALRx

I doubt it. That's why there's such a huge demand in the reefing community for things like Cole parmer masterflex pumps.

Do you need continuous duty for a cal reactor?

Its mostly AWC that I've seen for continuous duty.

All suggestions on the Reef Forums is for a continuous flow of water through the Reactor, around 30 ml/hr.
I run a line with my return pump. Would love to be able to control the flow. Right now I am limited to counting drip rate and estimating the flow with eyeball flow meter.

Controllable continuous duty peristaltic pump!!! This would be my ideal.

The pump should be sub $300 price point. I paid about $250 for a used Cole Palmer and it crapped out in about 6 months. Would be willing to pay about 300-400 for a controllable one.

What is continuous duty and why are they different?
If it is continuous, I would imagine it is not controllable or it would be called variable duty, no?
