This is the culmination of 4+ months of experimenting with toggling between alkalinity additives based on tank pH to maintain stable & proper pH while integrating the Alkatronic with the Apex and Dos pumps for additive control. In general, It's been working better than I could've expected. I started with pH as low as 7.58 and was lucky to average 8.00. now I have an average pH of 8.30 +/- 0.07 in a house with 2-3x atmospheric levels of CO2 and NO SKIMMER! One obstacle in my previous method was the inconsistency in how wizard sliced up the doses. Often times they're every 11 minutes or 14 minutes. Over time it became apparent that the Alkatronic would draw a sample at the same time a dose was being dispensed giving false high readings that'd over apply the brakes causing the next reading to be pretty low. Focustronic has mentioned the ability to schedule test times in a future update but they've also been promising expanded usage of the doser pump for over a year now... The alkatronic always starts it's test at the top of the hour and a sample is drawn between 60-120 seconds later. I have another thread detailing the past couple months here https://www.reef2reef.com/threads/i...-and-dos-for-stable-alkalinity-and-ph.784144/ . This explains most of the reasoning for the specific pH and alk numbers I chose. The important thing to note is that if your alk is "X.YZ"- you can modify X and Y to fit your desired alkalinity but keep the Z decimal the same.
The goals for this revision are:
⦁ pH control via dosing(no change from before)
⦁ Up to 4 alk doses per hour; avoiding alkatronic interference
⦁ Staggered Calcium(and potentially mag/ partC) doses that "chase" the alk dose ml for ml
⦁ Minimal amount of adjustments to expand with growth in demand.
With this method, all additives can be adjusted by modifying a single dos profile for the maximum demand and they will be dosed in proportion to the calcium dose. modifications can be made with additional profiles. The next post will contain all the code In case there are typos I missed.
