I plan on treating the 350 gallon spa with AhhSome and then dump for a refill. My question is, can I pump the spa water to my 12,000 gal. pool after cleaning up whatever slime/scum the Ahhsome dislodges? I will then refill the spa from the pool because the pool water is perfect. My well water has high "clearwater iron" that I have already dealt with in the pool water.
