Kalkwasser supplement using top-off system
 

Hi, guys,
I am planning to install auto top-off system to compensate evaporation. In
addition, I'd like to automate calcium and iodine supplement.
My plan is using 10G all-glass tank with power-filter I have in my storage.
In this tank, can I mix kalkwasser (or liquid calcium) and iodine?
Absolutely, according to their proportion for requirement. Also, using power
filter is better than nothing for amonia and nitrite developed in the tank
over time?

Thanks,
SW
