Yeah it is low. I started Friday, dosing 5 ml a day, when my Alk was 8.6 dKH and tested Monday and got 8.9 dKH. So I dialed back on Monday to 4 ml a day. I'll test tomorrow and see how it is. So far I'm liking how my tank is transitioning from Reef Code A & B with Brightwell Aminos to Kalk and Acro Power. I don't test pH but I'd love to see that increase that comes with kalk.4 ml a day? That’s really really low! Not saying its wrong but If you have something like 35 gallons of water that’s adding 0.004dKH per day. I’m just starting kalk and adding 200 ml to 20 gallons and I don’t have any corals, I think Coraline is consuming some and I’m probably just precipitating some dKH so probably not right either. I’m trying to find the right amount to keep dKH constant, work in progress.
Starting slow is an excellent idea, so don’t take my comment as criticism, it just made me go double check my math to be sure I wasn’t doing something crazy.
