Chlorine-Free Sun Shock Pool Ionizer and Purifier

Yes.

If you really want to save work, put in a center drain system. No more vacuuming! You can just make a current and all the stuff collects in the center of the pool. Regulations indicate that I think you need 2 now to be safe, but you can look that up on internet. Best thing I ever did! Perfect time to do it next time you change the liner.

Yes, it can. I've been using this for about 9 months in our above ground pool with a vinyl liner. We live in Southern Florida and it keeps the pool clean. I had to add chlorine once when I didn't clean the copper anode soon enough. Other than that one time the solar ionizer and purifier keeps the pool water clear and free of algae. Another good plus is that you don't get any stinging eyes and your skin feels clean when you get out. The copper anode does need to be replaced every year or so, but that one time cost is much less than purchasing chlorine and other chemicals to keep the water chemicals balanced. Overall, I am very pleased with this product. Makes my life just a bit less hectic.

I haven't had to replace it yet. It's pretty solid but it does get pitted. I have had it about a year but I don't use it all the time as I usually just use the power ionizer on my pump. It works better but have to change the cartridge every year.

We swim in the pool when these are in the water and have experienced no ill effects. The device releases no chemicals into the water.

Yes it will work grate for you .I think every pool owner should own one. best thing that every happened to my pool

No, but it is only a few months since first deployed. If there is a leak, it will sink.

I'm a retire engineer (EE/ChE). And no I have not disassembled the unit and while a bit curious don't intend to mess with what works and works well for my application. Another poster mentioned this is 25 y.o. technology. I remember working with similar technology in the 50s and it was old back then. (My first computer ran on punch cards) My pool and spa were in bad shape with regard to algae. Pump was not working so I put the unit in the spa and within a week to 10 days I could see the effects. Algae was not gone but it was obvious the unit was working. (Update pump was fixed last night so I shocked the pool and spa. Pool as expected was much better this AM, spa was in PREMO condition. One question I do have: what is the quantitative and quantitative make up of the copper electrode. I could run the test myself but don't have access to a lab & tools anymore as I'm long and well retired. An aside: The unit will remove iron and other chemicals from the pool water. These are relatively harmless but better out of the system. I'm mentioning this as they look VERY bad but are not indicative of a problem. In fact the unit is working as intended. Other positives: under the KISS principle (keep it simple stupid) Low cost (with 2 year warranty.) Low maintenance (my 8 y.o grand son does the maintenance. (at that age an at-a-boy from grandpa is golden) If it breaks its a pluck and chuck replacement (grand kids want to take it apart for the DIY solar panel projects). BYW Nothing on my pool can be replaced professionally for less that $150.

Yes, you still run the filter system but you'll use a lot less chemicals.

I use it in a 20000 gallon in-ground, fiber glass-lined pool. After 3 summer months of use (South Florida) I've not seen problems.
