Hey everyone. I wanted to get opinions on Aquarium stores having too high of ppm in their water. I brought my TDS meter into my store and tested their water and it said it was at 62! The owner of the store said over time the Salt water will creep into the Freshwater bin because they use the same pipe to connect them When distributing fresh and salt to customers. How accurate is this story? I just do not want to keep filling my 90 gallon cube with water that may or may not be no good. Any help appreciated. Thank you so much!
