So idk how this is possible. I soaked it in acid for 15 mins 30:1. Soaked after acid. Moved to ro bucket added dechlorinator and now it’s sudsing up again!!! I am praying this is just chlorine which was soaked in the rock from all the tap water. There are two air sticks in the bucket tooI’ve rinsed with a hose for 2-3 minutes and that’s it.. never soaked mine
