Check GPT’s math on alk consumption

[Faulkner’s maze]

Ok. - want to check the math here posted by GPT. Mostly curious to where it derived it’s numbers and whether accurate or not -

I use both kalk and AFR. We are going assume that over 24 hrs alk consumption is fairly stable in in the beginning and end are generally within .05 (varies between 8.4 and 8.35)

So for AFR it has:

Assumption:
As a general rule, 1 ml of AFR increases alkalinity by 0.09 dKH per 100 liters (about 26 gallons). -





Determine the alkalinity increase for 1 ml of AFR in a 65-gallon (246-liter) tank:

.09 DKH/100 L*246 =.221 DKH
.221*14 ml (daily dose) =3.094

For kalk-650 ml daily
5.6dKH×0.65liters=3.64

Total daily consumption: 6.734 ignoring the system consumption for now.


TIA.

I would assume it is not correct

I would assume it is not correct

Prob not. The underlying calculations are prob correct but unclear where it’s getting its information from in respects to how much kalk/afr raises DKH per liter. Can’t verify it..

Chat GPT makes terribly stupid math calculations. Never use it. In one case posted here, it made an error of a factor of 1000.

I’m tired of checking and rechecking a flawed machine. I’m just going to show you how you can answer your own question.

We will use this calculator:

14 mL of AFR in 65 gallons boosts alk by 0.35 dKH. AFR is 13% more potent than my diy recipe #1. Thus, use my entry and multiply the result by 1.13.

Using the same calculator, 650 mL of limewater (aka kalkwasser) boost 65 gallons by 0.3 dKH.

Total addition is about 0.65 dKH.

Thanks. Even with all the SPS I have I didn’t think I was consuming 6.x DKH a day!

You’re welcome.

Happy reefing!
