Anyone use a Drew's doser for an ATO pump?

Anyone use a Drew's doser for an ATO pump with an Apex? The PMUP pumps too fast with kalkwasser in the reservoir and can cause a pH swing in my 70 USG.

I would say it's too slow for a ATO. Isn't the speed like 1.6ml per minute? I used toms aqualifter pump and worked well.

It will not work as an ATO or kalk dosing pump. You want a heavier duty, continuous pump for that

How about 19mL per minute? For ATO?
