The hot tub in the hotel at which we are staying has foaming bubbles on the water when the water is churning at any speed. The high speed has a TON of bubbles and foam. Is this normal or should we stay OUT?
It's most likely just soap from people who didn't rinse/shower off before getting into the tub. Hot tubs usually don't have algicide added to them and in a commercial/public spa it's likely they are just using chlorine directly without any CYA. So if anything, the chlorine will be too strong.
