Kalk and Top up Dosing Pump for very low volumes ??

[Fish]

Marie,
I thought about it but I understand repeated stop/start will reduce the life of a pump - guess that doesn't matter much when the pump cost $20 though
Another thing is that I'm dosing kalk and I undertand its better to drip kalk slowly otherwise it will cause a ph fluctuation. Do you think that would happen when the pump kicks in all of the sudden? I like for 10mins every hour?
Great ideas everyone
