A. At times you may experience an organic smell. This simply means that All Natural Water Treatment and Conditioner has found contaminants and is working hard to remove them.

Q. Why did I get rash spots shortly after using the spa?
A. Hot tub rash or the technical name, pseudomonas is bacteria in the water that has not been sanitized or filtered. Check the levels of your sanitizer, ph, alkalinity adjust accordingly. Drain the water and refill with fresh water is water balance can not be maintained.

Q. My water smells stagnant. What do I do?
A. This is typically one of two different issues. Check your sanitizer level or ph and alkalinity levels. If the sanitizer is low the water can be cloudy, foamy, smelly. If the ph and alkalinity are out of balance you could have some foam, or just an organic smell.

Q. Is there an easy way to know when to clean a cartridge filter?
A. Yes! Cartridge filters work on the “clarification process.” They remove the oil and debris from the water. If the sanitizers are in balance and you have cloudy water it’s probably time. On average once a month, more often if the tub is used heavily.
