I PURCHASED A NEW HOT TUB. I NEVER OWNED ONE BEFORE SO I RESEARCHED ALL THE CHEMICALS AND THINGS I WOULD NEED. I HAD PURCHASED ABOUT $200 WORTH OF CHEMICALS. I STUMBLED ONTO AERO-SPA OZONE PUMP. I USED IT FROM DAY ONE ON MY SPA. THE WATER I USED WAS SOFT WATER WITH NO CHLORINE IN IT. THE OZONE PUMP HAS KEPT MY SPA CRYSTAL CLEAR. I HAVE NEVER ADDED CHEMICALS. I HAVE OWNED THIS FOR ABOUT A YEAR NOW. DURING THE WINTER NEVER REALLY OPENED THE TOP FOR ABOUT 3 MONTHS. WATER WAS CLEAR! I DID HAVE TO TURN MY OZONE PUMP DOWN TO 1.5 HOURS TWICE A DAY. THERE WAS A SLIGHT BROWN RING FROM THE GAS ABOVE THE WATER. CLEANED IT OFF THE 1.5 HOURS SEEMS TO WORK PERFECT. WATER CLEAR AND NO RING. MY HOT TUB IS A MEDIUM SIZE TUB. SO NICE NOT HAVING CHEMICALS IN THE WATER. JUST CLEAR SOFT WATER!
LOVE MY HOT TUB WITH THE OZONE PUMP!
