The Avtech system allows me to download 30 days of data; I did so today, capturing pH & T data from 4/24 -> 5/16 @ ~1:30pm.

Notes:

• Temp-w-3 probe is in the header tank
• wish-Internal Temperature is recording the room temp
• Durafet 3 is on the top shelf in a K population bucket. The top shelf houses HL & K groups, and receives a large amount of air bubbles, which I believe is driving the pH up to ~8 as it mixes with ambient air.
