Good news! I found what the problem was…my dechlorinator :O You see, I use seachem prime as my dechlorinator, but a ml of prime treats 10 gallons…thus, I dilute it with tap water so that 1 ml treats 1 gallon. Doing some tests over the past two days reveals that this prime/tap mixture has a VERY high TDS…high enough that a single ml can single handedly increase the TDS/conductivity of a gallon of water by the observed amount, and presumably play havoc on the PH as well. I have started adding vinegar to this dechlorinator mix to counter that…will have to see how it works.
