Jacuzzi ProClear Mineral Spa Sanitizer 2890-185 Maintenance, Clear Water, Enhanced Softness, Controlled Release Technology, Compatible with Jacuzzi Hot Tub's Filtration System

Great product

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!

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!

I use this every water change in my jacuzzi spa. I use 4 a year. Wish they were cheaper, but it does have silver in it which should make up some of the overall cost. I think it’s working well in my tub.

I thought the cartridge would have still been it's cellophane wrapper and just no box. Cartridge was not in factory cellophane and appeared to have possibly already been in water by the film on cartridge so I have no idea how long this will actually work or if someone pulled the wool over the sellers eyes and it will not provide the service I expect. But you get what you pay for.

Keeps water clean with minimal maintenance

Very easy to install.

Did not fit my spa
