MegaChlor-CD Saltwater Chlorine Generator with Auto Chlorine Monitoring, Automatically Activates as Needed, for Swim Spas and above Ground Pools Up to 17,000 Gallons

FAST SERVICE.Nice product.

Update 8/14: works amazingly well. After being away over a month the hot tub levels remained perfect and water clear. Photos added. Original: I only wish I knew about this years ago. I converted my pool to salt water years ago and love it. One of the best features is that it only cycles on (smarterspa model) when the sanitizer level drops below a certain threshold. This is great for us because our hot tub is covered, and used irregularly in terms of frequency and number of occupants, so manning the chemicals has always been a challenge. Day 1, I installed it, it ran a cycle at level 3 (default) with only 2/3 of the weight of salt recommended in the manual as per the youtube video recommendation. The sanitizer level rose to pool levels but needed to be higher for a spa, so I increased to level 4 and later that day it cycled again. Day 2, spa levels are all perfect with sanitizer levels at the desired level for a spa. This was SO EASY! Now, my hope is that the unit has longevity. From my pool salt chlorine generator experience, my expectation is at least 3 years, hoping for 5. I hope to come back here to update my review if my expectations are not met, especially if it dies within a year. My only negative is that the video on youtube by the manufacturer talks about being able to install this inside the housing attached to the spa electrical (advanced install) but I did not see any instructions for this. I will try to reach out but I would have liked to see instructions and/or a video online demonstrating this. We are very excited about this, and although the price is not as low as I would like, it is still in an acceptable range for the convenience and chemical cost savings if it lasts at least 3 years, in my opinion. It is priceless in terms of the improvement to the water quality for my skin, however, and as such as totally worth it.

What a difference, I have tried chlorine, bromine and mineral even frog spa and all worked but the maintenance and smells were just not what you want to relax in. Seems after you drain the water refill check the water then come back in two days to a sour smell. Our friends have a salt water pool with attached hot tub and their water always seem to be nice with no harsh smell. Ordered this after talking in depth to ControlOMatic and how this should help us out. Drained hot tub, refilled, We are lucky as our water is spot on for PH, alkalinity and hardness out of the tap. Added the amount of salt calculated by the gallons of water, took all of about 2 minutes to install the Smarter Spa, most of that was getting it out of the box. 3 screws, 2 to hold the box and one to hold the cord. Dropped it in and it read salt overload. drained some water added fresh, still salt overload. Drained about half the tub, added water back dropped the module back in and it registered Salt High which is fine per the directions. Lesson learned, add about half the salt and then test. This unit reads the salt level instantly so no need to wait. It produces the right amount of chlorine and turns itself off and when it needs more it turns itself back on. Only 5.5 DC volts. I could not be more pleased with it and a 40lb bag of salt from Walmart is less than $7.00 I only needed about 4 cups so I am set for the next 5 years for salt. So no more aroma therapy to cover up the yuk smell for us.

Product doesn’t work. Tried to shock it to get chlorine going and still shows zero chlorine. It will go through one cycle then not turn back on. Would really like for product to work but seller is of no help. Tried contacting seller but no response. I am now one day past sending back.

In September 2022 I purchased a new Jacuzzi J-245 hot tube to replace an old one. One thing I didn't like about my old hot tube was all the chemicals that needed to be added to keep the water clear and sanitary. Often, due to lack of use or overuse, the water would get cloudy. It also frequently smelled of the chemicals that constantly needed to be added. My brother has a saltwater hot tub and loves it. So, even though my new hot tube was not a saltwater model, I decided to convert it by adding salt and the ControlOMatic Chlorine Generator. I purchased the ControlOMatic on Oct 24th 2022 and immediately installed it. It's now been in operation for 11 months. It's been wonderful and a night and day difference in my hot tube experience. It took a week or two to dial it in. Once that was done, it has worked flawlessly. It keeps my water crystal clear at all times. I only add a couple tablespoons of powdered shock once a month. I use my hot tube almost everyday year round. My typically routine is to hit the manual "on" button every time I finish using the hot tube. I set my ControlOMatic to level "5" which seems to be perfect for my hot tube. I do the normal maintenance of submerging the end of the ControlOMatic in vinegar every month or so for 15 to 30 minutes. I change my hot tube water every 6 months. It seems like my new hot tube is maintenance-free compared to my old hot tube. I like not smelling like chlorine after using the tube and not having to worry about forgetting to add chemicals when I'm on vacation for a week or two. I don't know how long this device will last, but I will definitely buy another one as soon as it fails. My hot tube dealer did not recommend that I convert my new Jacuzzi to saltwater and told me that I would be voiding the warranty, but I listened to my brother instead and went ahead with the conversion to saltwater. I'm so glad I did! I think my dealer had his own interests in mind because I haven't purchased any chemicals from him in almost a year now. Anyway, that has been my experience with this device. I love it and will not go back to constantly adding chemicals. I hope this helps you with your decision. :)
