I used filtered tap water instead of distilled. Whats going to happen?
Your credo is going to become less and less efficient over time. Filtered tap water is full of all the dissolved minerals which will ultimately plug your credo. The PH is balanced in tap water with chemicals which may interfere with the PG and cause variations in your humidity. Spring for a $0.69 gallon jug of distilled water. It’ll make a difference.
