After a few weeks I have dialed-in my TM 3-part Balling system. I am using Kamoer dosing pumps, dosing every hour (24x/day). Over the past week I have noticed that my alkalinity is 9.4 every morning around 8am (as lights come up) and is 9.2 every evening around 6pm. My pH dose NOT swing and is always at 8.2, possibly 8.25 but that is being subjective on the color. My question: can coral have a higher dKh demand during the day than at night, causing my alkalinity to slightly increase overnight? If so, should I decrease my dosing volumes from 8p-8a (overnight) just a little (to maintain an alkalinity of 9.2 throughout the day)? Or, is a 0.2 dKh swing once a day not an issue? I have a Reefer 525XL which is approximately 125-130 gal of total volume (excluding sand/rocks) and I am dosing 175 ml of Parts A/B/C daily, or 7.3ml every dose (every hour).
Thanks for your help!
