  • I have a spinal cord injury from a bad car accident and don't have a lot of extra ...
I bought my 2013 Jacuzzi J425 used on Craigslist for only $2000 last summer 2017, the owners had the org receipt for $12K, I have a spinal cord injury from a bad car accident and don't have a lot of extra money so I felt blessed to get such a good deall, I have owned a Hot tub before but I have to tell you this thing is AMAZING! Gone are the days of one filter, Mine takes 3 Large filters and has the Sundance Clearray XL UV light system installed on it, Everything was working just fine with the usual water clarity issues I have battled in the past until I found out about this Optional ProClear Mineral Sanitizer. I ordered it and it installs inside the Blue cap on Top of the Left Large filter. LET me tell you, I was and still am Amazed at how Clear and beautiful the water is in this Jacuzzi. It is sparkiling clear and I'm not just talking about for a week or two. I bought the Pro Clear Mineral November 2nd 2017 and the water is still Clear. I have changed the water once since then because I am the only one who uses the tub and I always take a shower first. Even after filling the tub again the sanitizer was and still is working like on day one. I ordered a new one today only because the bulb will need replacing on 6/15/18 so I will be changing all the filters and sanitizer at the same time. One more thing to tell everyone is to buy a water filter that scews onto the end of your garden hose so you literally fill the tub will filtered water right off the bat and that makes a big difference. I only know this because the orginal owners gave me that as well when I purchased it from them. Have a great day and God Bless! ... show more

  • Water is clear and clean, no odors.
Perfect fit for the filters in my Jacuzzi. The water stays clean and clear, with no odors. Reduces the need to add expensive chemicals, so it practically pays for itself. Highly recommended!

  • Spa water cleaner
These things are recommended by the manufacturer so I use them. I really have no way to know if it works. It's very simple to install, just attach to filter lid.
