By ppm's are you thinking CO2? They hover around 400-600.What was the ppms and pH of the runoff?
Humidity levels are a bit high, hovering around 70%, have ordered a second dehumidifier, so hopefully I can get it down to 50% soon.
I highly doubt it is pH, as the water has perfect pH. But I will check out the pH of the runoff later if you mean it is necessary?
