My latest ICP test shows a fair amount of arsenic for the first time. A few questions:
- Where might have arsenic come from? Its been at zero in my last 2 tests. The only change to my system since the last test was the addition of AL 99 PO4 remover.
- Is there any way to remove arsenic without a water change?
