  1. My pool service recently reversed the compu pool salt system so that the intake is now connected to the pool. Is there a my good reason for this change. I want to be prepared for his answer before I question him.

    1. Hi Paul, The CPSC24 cell has to be installed with the water flowing from the input port to the output port for the cell to work properly. The orientation of the cell should be noted on the cell casing with a “flow arrow.” The cell should not be reversed.

  2. That sounds awesome! I feel like having a salt water pool would be a whole lot nicer just because you wouldn’t have to worry about how nasty chlorine is. Plus, you could probably open your eyes without it hurting a lot. Sounds nicer to me. Is there as much maintenance, or is it just the salt cells you have to replace?

  3. Any salt water pools in Utah? We live in northern Utah and don’t like the chlorine pools. This sounds interesting.

  4. Our pool for the past 2 months has had a 0 chlorine level. The salt generator is working fine. We have added 8-9 lbs. of chlorine I a day with no results. Any suggestions?

  5. When adapting this cell to my pool filter I noticed my salt cell (only 2 months of use) had degraded almost entirely. And the water drys leaving a white powder that irritates sensitive skin. My daughter’s eyes were nearly comprimised. I’m not sure what this machine is doing to the water… but it has an almost unnatural slippery feel.

  6. a couple of questions… First, you mentioned that salt can be corrosive to pool equipment. Is it any more corrosive than muriatic acid or chlorine? It seems to me that proper rinsing of decks, etc would prevent very much corrosion. Second, if the chlorine generator is working properly, would there be any reason for additional chlorine, aside from the ppm being reduced by replacement water, rain, etc.?

    1. Salt will eat away at metal railings, diving boards, and even decks. That is why manufacturers make Marine Grade railings, ladders and diving boards. There are also deck treatments that can be applied to the deck to protect it from salt. The application process is like adding Thompson sealer to a wood deck.

      The only additional need for chlorine that I can think of is after a big pool party. A bunch of people getting in and out of the pool, carrying dirt, body oils and who knows what else.

  7. Hi I have a question- I plan to get a permanent above ground pool and was told at the pool store that a salt water system will corrode the walls of the pool and it will void he warranty. I have a salt water system right now with my temporary soft sided Intex pool but he said that was ok because it the walls are soft sided. Will it really corrode the walks or is this a scare tactic bc I really like the salt water system alot better than chlorine. I read what you said about getting a sacrificial annode and a nickel cuproheater (bc plan to get heater).. any other considerations?

    1. In my experience, the walls hold up relatively well because they have several layers of protective coating. The inside of the wall is protected by the liner, and the outside is somewhat protected from spillover by the pool’s top ledge. The top rails, rims, and caps are the most likely to be affected by salt water the most because of splashing and swimmers getting in and out of the pool. If your pool has all steel parts, I would avoid salt, but a Hybrid is a little more expensive but will hold up better.

      A hybrid pool is made of a mix of steel and resin parts. There are various combinations of steel resin parts, depending on the pool model.But their purpose is to have the parts most susceptible to rusting to be made of the rust-proof resin material. These are more expensive but would last longer on a saltwater pool.

  8. This is so helpful, I am planning on installing a pool, and considering on a salt pool.
    I have a reaction to chlorine, in that my heels crack when I go into a chlorinated pool, do you think i may have the same problem with the salted pool

  9. We are purchasing a house that is totally underground and yes it has an indoor pool and hot tub. The house was built in 1979 and been not been occupied for the last two years. The humidity and ventilation don’t appear to be working well, the “pool smell” of chlorine hits you when you walk into the house. In looking at the pool equipment, it looks to be a mix of very old and not so old, but never the less a piece meal approach. The pool is not a large pool or a lap pool, relatively small in size.

    We would like to change the pool to salt water, that said is it practical to use the some of the existing equipment or in the long run will it be more economical to replace the entire system and reduce overall maintenance?

    1. I have a 15′ x30′ indoor pool, and am on my fourth heater. The heater cores have been pulled and are packed with a white (calcium?) Substance reducing the pressure needed to run the heater. The last pool service man told me I should be filling my pool with water that runs through my house’s water softener (salt) instead of straight well water. I am afraid that would put too much salt into the system and deteriorate the heater and pump. Your advice would be greatly appreciated. thanks, Nick

    2. Generally, yes it is better than traditional chlorine, but this will depend on your particular installation. Do you have metal railings, deck furniture, or a newly plastered pool surface?

      Newly plastered pools required 30-90 days to cure before you can switch over to salt. If you have metal railings and ladders, you can either replace them with salt friendly equipment or install a zinc anode to prevent rusting.

    1. To be on the safe side I would direct it to the nearest drain. The salinity levels in a salt pool are relatively low, but over the lifespan of the pool you will be dumping a lot of water onto those bushes. The water may dry up but that salt is going to stay put.There are some bushes that have a higher tolerance salinity.

  10. We only have a skimmer, not a drain on the bottom of the pool, and a polaris vacuum that helps circulate water in the deep end. Would there be any issues in converting to a salt water pool with not having a drain at the bottom of our pool?

  11. I live in a condo and we changed over to a salt water pool. Best thing we ever did. We have more people swimming because of how nice it is and it doesn’t ruin your bathing suit or dry you hair out and the water is so soft. But I have a question. We had a pool company convert it for us but we have someone that lives here that wants it changed back because he said it put etching on the walls which is not true because I pointed out the etching before we ever changed it over. Now my question is our pool has stainless steel walls and concrete bottom. The pool has been salt water for 3 years now and NO PROBLEMS at all. But one individual that never even uses the pool wants it back to chlorine. I realize the salt can be harmful to the ladder and any metal screws that are used instead of stainless steel screws. But that is a simple fix. We also have it heated with NO PROBLEMS to the equipment. This individual printed out info on salt water pools that were 10+ years old. It said you could not use salt water with stainless steel walls in a pool. And that it was charged and this individual said it was like swimming in battery acid. But everything I pull up says you can as long add you take precautions. Can you settle this debate for me, before they change it back. I can prove that when it was chlorine that we spent hundreds and hundreds of dollars on chemicals and it was never right. Not to mention we had to drained it twice, at least half way one summer because the acid level was way too high And the Health Dept said we had to fix it and the only way to do that is drain it half way And refill it. And with the salt water pool the chemicals have never been off one time in three years. Please help before they change it over to chlorine again. EVERYONE that actually uses the pool does not want it changed back. Only the ones that NEVER use it do. I need some info to supply to the board saying it is okay to have a salt water pool so they will not change it back. I need help!!

    1. There is a lot of info in this post, but I believe the question is, can you use a salt chlorine generator in a pool with salt pools?

      The answer is yes. you can use an SCG on a steel walled pool. Generally, steel wall pools are covered by a vinyl liner. The steel does not come in direct contact with the saltwater. The person calling the water battery acid is being hyperbolic.

      If you are worried about rusting, install a sacrificial zinc anode. Large ttank er ships use them to prevent the steel hulls from rusting.

  12. I have a new salt water pool that was installed about two months ago. We continue to find sand in the pool. We cannot figure out where it is coming from since we don’t use sand to clean the water. We believe there may be a leak and the sand is actually what was laid under the pool liner during installation. I don’t think it’s a type of algae. We can’t find any damage or tear in the liner. Any thoughts before I contact the pool company?

    1. I do not think the sand is finding its way into the pool via a crack in the basin. If there is a crack in the basin, water would rush out, dirt would not get sucked in.

      What type of filter do you use? If you have a DE filter, the sand you are seeing could be a DE powder. Used DE can become a gray or beige color. The powder can reach your pool a few ways but the common causes are torn grids, cracked manifold or backwash. The latter happens if your pump loses prime when it is turned off and the water from the filter backwashes from the tank backward through the main drain and skimmer.

  13. Hello there Matthew Simmons. We are running a business which includes swim lessons for baby, or kiddies who are several years old, would you recommend salt water pools, and we plan to install Filter + Variable Pump + UV, any suggestions? my email: L1nzo@outlook.com.

  14. A general question, what’s the right procedure during winter? East Coast, 20°F. Cover and leave water in? Empty it?
