Any advice would really help... Aquarium is a 72g w/20g sump. SWC 160 cone skimmer and a mixed reef but mainly SPS and a clam(tripled in size over the last year and half) I'm switching from using kalk in my top off(float valve drip). Mainly because I don't want to mix anymore, doesn't seem to be keeping up with CA/ALK demands and once and a while my float valve will clog up. Plus I manually dose 2 littles fishes A and B daily. Getting tired of doing both plus a weekly water change(10g). So, I'll be using the BRS 2-part solution and will be dosing via a dosing pump and just using fresh RO/DI for top off. I'm not sure when to dose CA and ALK. I know that the ALK will raise the PH. So should I dose CA during the day and ALK during the night or just spread the doses out throughout the day and night? Foe example: dose both every hour(CA first half of hour and ALK second half of hour).
