Got it solved! $12 bare 12v dosing pump on amazon... ordered yesterday, got it today in the mail?! Shipped free with amazon prime!

Thanks, jack!

(Prefer dosers over aqualifters, no siphon)

These are really decent, I am using one with pwm dimmer to dose Kalk. Cool!

 

I do find they wear out but at 12 bucks no big deal.

 

Dimmer is cool as you can slow it down so it is quieter. Amazon has those too, 8 bucks I think.

Toss in project box for neatness / waterproof

 

Thanks for update

Well the Steve the PWM works well, but I am burning through allot of these low cost peristaltic pumps.  

 

On my third one now.  

 

I use these to dose a couple gallons a day of kalk water per day.  They just are not up to the job for that much use or I picked up a bad batch.

 

If someone runs across better ones I am all ears.
