I just bought a TDS meter and found out that my tap water is generally 40-41PPM, which I understand is near the threshold for safe top-watering. Should I let the water sit for a day before using it to let any chlorine dissipate, or could I water my plants directly using a hose? The plants are outside, so they get flushed whenever it rains and I plan on keeping some distilled water around for occasional flushing as well, not to mention regularly checking the TDS of whichever water I use.
