My ultimate calcium reactor setup

10% dolomite. ARM advertises to have more Mg than others so you may need less. Honestly I just guestimate a little bit in on top of the ARM and my levels are always within range

and to answer the original question the digital is not needed.

Now I have a question for you: where did you get your peristaltic pump from!?

 

Grim,

C02 tank? Is that for injecting the keg of your home brew beer?

I naturally carbonate mine in the bottle.

 

Co2 is used to lower the ph in the reactor so that it can break the media down! And it used to be for my kegerator, but I broke it down a couple years ago .

 

Ok, now I'll answer! I got a hell of a deal!!! Brand new! $242.50 shipped!

eBay - New & used electronics, cars, apparel, collectibles, sporting goods & more at low prices

 

Note: Here is what I have on order so far.

Geo 818 Calcium Reactor - CR818
Aquariumplants.com electronic regulator w/ lcd - CarbonDoser Electronic Co2 Regulator
Cole parmer continuous duty peristalic pump - eBay - New & used electronics, cars, apparel, collectibles, sporting goods & more at low prices
Already have an apex with PH probe to control the unit.


Should I get the coarse or extra coarse ARM media?

Do I need any other fittings, etc?

When I go to hook this all up, should I just stop my dosing system all at once?

And I updated the first post with this.

 

You can stop dosing. You will be checking the Alk regularly for awhile to get it dialed in. Just add 2 part as needed to keep parameters in line.
Nice deal on the pump, I picked up a used one for 55
You can pick up the Tubing from us plastics

 

Here is something froma RC thread

Also cole parmer is proud of their tubing but you can get it from US Plastics
just find the tube size dimensions from here
masterflex pump, masterflex pumps, masterflex tubing pumps, masterflex peristaltic pumps

and got it from US plastics

Oops... File Can't Be Found
Cole-Parmer----US-Plastics P/N----Inside Diameter
L/S 13-------------57316--------------1/32"
L/S 14-------------57317--------------1/16"

If you go with LS 17 1/4 inch tubing will slip inside it

 

Nice, thanks for the info! I think I found everything I need. I have gotten a lot of help from someone at RC. This is the same person that turned me on to Cole Parmer pumps and helped me find that deal on that new one. Here is what he set me on. If anyone sees anything else I need to order let me know.

 

Also, what kind of salt are people using with there calcium reactors?
