Swimming pools blog

I have a 25k IN pool with an “overflow” hot tub on the end. I
regularly run the chlorinated, filtered water into the hot tub which
spills into the pool, but the hot tub gets “brown” and does not look
nearly as nice and crisp as the pool. Suggestions? The previous
owners repainted the pool before selling the house, but not the hot
tub, so it’s already a lighter/greener color than the pool, which
makes it even more difficult to pass it off as clean….haha
