Super easy ratio based off of ca ppm consumption per day/week, whatever. And keeps pH up. Was the answer i was seeking. And i did the lazy ATO method, a drip method like pops (@Fudsey) has is the best delivery though, imho.Kalkwasser is a possibility need to nail down numbers see which way I will go. Not crazy about adding it to ato so would drip it in or use doser which I’m on fence about as well. I may just be able to maintain alk steady and be good to go.
