My Tank Thread
Due to the alk lag with afr, i dont think this is advisable.
I dose each hour, 24/7. I check the alk and calcium weekly and adjust based on the trend of alk. If its going down, more afr. I use common baking soda to bring the alk closer to target, if low.
When determining your dose check alk every 2 or 3 days. Alk and calcium are used mostly at the same rates, per the chemistry.
Use the afr powder to lower your cost.
Adjust afr to the alk trend. Use something else to get to target dkh.
I agree. I do not recommend fully automated measurement and dosing of AFR.
On the other topic, AFR, like kalkwasser, is a little calcium heavy relative to alk, so if water changes do not beep it from getting too high (it may well) then a little less AGR plus some normal alk will do the trick.
