Do not like the chlorine if I don't have to use it I will be happy or an alternative. Our tub is 140 gallons. Thank you** A: No chlorine. We have a non chlorine hot tub. It have an ozinator system on it which keeps the water cleaner and clear. We use the mineral stick sanitizer with the filter to help keep it sanitized. It fits inside the filter. Use Leisure Time RENU5 Renew Non-Chorine Shock, we buy the 5-Pound container before and after each use of the tub, just a capful or 2 and turn on air jets for about 60 seconds before getting in.... do the same when you get out.... to mix it around good. Your hot tub needs air to the water occasionally when not in use, so 1/2 opening the lid for 12 hours 1x a week is good...keep the filter clean (we clean in sink with sprayer then set in top rack of dishwasher, run dishwasher (no soap/detergent) on high hot cycle, and air dry in sink over night.) People should be free of wearing perfumes or lotions prior to getting into tub if at all possible...that is what ends up clouding up the water the most.... and rain water. So keep covered on rainy days. Unit off. Hope this helps... if your unit does not have the ozinator on it...you can have one installed for around $400 possibly less, depending on the unit. If it has an ozinator in it, you should never use chlorine in it then. Hope this helps. **Q: Our current Pro Clear Sanitizier is blue and twists onto the the top of the filter. This one is yellow with different top. Can we use this one?** A: They are both made by Nature2 and the only difference is the color and the cap. I popped the cap off my blue one and put that on the yellow one as they are much cheaper and easier to find. **Q: This was offered with the intex inflatable spa but doesn't fit filter. why is it offered with the spa? is there a mineral filter that does fit?** A: If it doesn't fit inside try to stick/wedge it beside the filter/housing. If that still won't work just drop it in the bottom of the tub and kick it around a couple times when ur in. I also pick it up and hold it in front of a jet for a min or so while I'm in sometimes...works just fine. **Q: How does this mount in a horizontal filter** A: Hi Jim,Thank you for your question. Just insert it inside the spa filter and ensure it does not block the flow of water through the filter.
