That would be great. In the mean time I think some interpolation is in order.Ok I’ll do some testing today and report back. I switched my Bolus dose off for today and I have just run a test and kh is now 7.6. It’s 08:41 in the UK
I see one problem in the interpretation. That is using the 1 dKH change as daily consumption, while the bolus dosing and KH measurement points are not aligned. So, the 1 KH is actually measured over 18 hours and not 24 and some interpolation is in order.
If assuming, the FM calculator is wrong, the KH mix is 100 grams of bicarbonate per liter, then a dose of 250mL in 650L would give a KH rise of about 1.285.
Exemple time line on october 14th:
6:00 AM KH measurement 7.7
8:30 AM Bolus dose
9:00 AM lights on Bolus style (120%)
12:00 PM KH measurement 8.7
6:00 PM KH measurement 8.2
12:00 PM KH measurement 7.8
From 6 to 8:30 the KH will drop slightly below 7.7.
These 1.5 hours are problably negligible, maybe 0.05-0.1 KH, looking a the data from other days.
After bolus dose and lights on the dosed KH will be consumed during 3 hours before the next KH measurement at noon. Additionally, the max light output should (according to the Bolus manual) be during the first few hours after the bolus dose.
So at least 0.5 dKH consumption in 6 hours. Or 0.25 in 3 hours. Likely a bit more because of the higher light intensity during the period. This means that the peak KH directly after dosing the bolus dose was likely close to 9 dKH.
Therefore, the daily KH drop would in my opinion more likely be 1+0.25+a bit more+maybe 0.05 = ~1.28 to 1.29 KH consumption a day.
