BRS 2 Part Doser

 

Noob question: what is a 'two part' doser?

The "two part doser" is marketted to dose BRS's own two-part solution (i.e. calcium part and buffer/pH part). It's a dosing pump that can be used for just about anything.

 

That said, I have used similar dosing pumps and didn't care for the reliability of the cheap ones. The one I had eventually broke the motor spindle-to-roller connection which left the motor turning and doing nothing after only a bit more than a year of functioning.

 

When dosing Kalk, the best way to do thing is to push RO water into the Kalk solution in a reactor (which is sealed) which in turn pushes kalk into the tank. For that, the aqualifter pumps are the best I've used, especially because they're only $10 each. They work on a diaphram pump system which means that ideally, you shouldn't expose the rubber to high pH solutions, but at $10 each, you can use up 1 per year and not hit the price point of the dosing pump for a decade. You can put a John Guest fitting valve on the output of the aqualifter to control the flow.

I had 2 of them. They are worth every penny. I've never seen a bad review of them either.

I've been using those pumps for about a year now. Love them. no issues whatsoever.

Working Well for me also has been up and running for a few months.

I use them to dose cal and alk and I've never had a problem with them. After almost a year of use they were still dosing the 1.1 ml they advertise after testing them last week. Great dosers IMO. I also use their similar 50 ml/min top off pump.

I love mine. They are great when used with a controller>

Excellent info. Could I mix my Kent Cal and baking soda together so I only have to buy one of them?

[Stephen]

No you can't mix them. If you're interested in only using one you could use one of the all in one cal and alk products that are out on the market. I don't have any experience with them though.

Interesting. What happens if you do mix them? (I gotta ask).
