Kalkwasser dosing pump recommendation?

[Dduck87]

I’ve recently realized I need to start dosing Kalkwasser and magnesium to keep up. Any recommendations on a reliable pump that won’t break the bank? Tank is 4 months old. Pic of latest parameters listed

I use a kamoer fx stp continuous..works great. Can find them used for cheaper or on ali express.

The pump I used is no longer available.

How much do you think you will dose daily?

I switched my dosing pumps to the Neptune DOS recently and wow, it is really worth the money. I dose the Kalk with it and it’s so intuitive and easy to calibrate and adjust.

With respect to mag, not really sure why you need to put that on a doser. The level falls so slowly and adding a larger amount once in a while has no detrimental effect. I just pour what I need in once a month or less. And I am using about 30 gallons of kalk plus two part per month for reference.
