I was thinking about how to give suggestions on what to add to the pool. For example, say a newbie who doesn't know anything is using this app and their pH is 7.5 within acceptable range 7.5-7.8. I would give no suggestions really because things look good. The number would be green. Now, if they are at 8.2 i would want to turn the number red and give them the suggestion to add XXX to lower it.
Should I give them a range, like if you want to lower it to 7.5 add this but if you want to lower it to 7.8 then add this? or should I shoot for the middle (like 7.6) and give them the numbers to get to that level.
So then, for an advanced user who always wants their pH to be at a specific target. I would allow them to enter this in the advanced settings and it would always give them the amounts to add to get to their target, but will still give them a 'green' number if they are within suggested ranges. Number would turn red if they were out of range.
Do you think that works or would you guys like it another way?
