I have a 200 gal spa. The manual says to keep the salt level between 2000 and 3000 ppm. The test strip I use shows 2000, but the "High" light blinks

OH, and my 500 gallon 8 person hot tub is in a heated and airconditioned building. So I took off the 150 pound cover and trashed it. I went to Menard's and bought 2ea 4 foot by 8 foot sheets of insulation styrofoam insulation 2 inches thick. I think they weigh around 8 pounds each.

I found the salt strips to be a bit tricky (compared to chlorine etc chemical strips). They take a long time to read, so I was just laying the strip in the water sample. You need to stand the strip up in the container so the bottom is in the water and let it sit. The strip was reading far lower than it should have when laying in the water vs standing up in the water. Perhaps you are having the same issue and it really is higher than 2000ppm. I started out with too much salt because of this as well.

The test strips have terrible accuracy, mine read 1000ppm off from the Taylor test kit from amazon, taylor salt I think, very accurate and around $20. Good luck!

Check the type of salt you are using. I had the same issue using dead sea salts which are potassium and magnesium salts. I suspect that the test kit measures NaCl which is what the manual specifies. The system seemed to work just fine but to appease the sensor I changed the mix to 30% plain pool NaCl salt.

That kept happening to me and I would unplug it and let sit for 1-2s day and plug back in then it would do it again in a few days finally mine just did not work anymore at all only lasted 1 season.

Add some water then cycle the power on the saltron. Repeat until its in normal range. It worked for me.

Our system continuously said low salt. We contacted the manufacturer and we were sent a new copper plate. Still didn't work. We gave up and now use the old chlorine method.

I have the Sundance Optima and I just use the Sun Purity that has a slot for it near the filter and AquaChek brand test strips that tests for monopersulfate which covers ph and alkalinity, the unit has an ionizer in it. I don't have info on the Marin spa

That could be. Take a 20 oz water sample into Leslie's Pool Supply or your local pool supply store and have them check the salinity to make sure. They may even check it for free.

I used it in a 25000 gal. pool. I worked great in my pool. I'm not real sure how it would work in a hot tub. In my hot tub I throw in a tablespoon of chlorine once a week and that seems to work well. I think they have a smaller model for just hot tubs.

Do you have fresh or salt? If this is for fresh water 55 gal the API M will work just fine

Not sure because I have a 500 gallon tub. I use one capful Of non-chlorine After each use or once a week. Try calling the manufacturer for an answer or your local hot tub specialist good luck

plain old table salt works fine. 1-2 teaspoons is sufficient in a small footbath. More makes the machine beep a warning that the AMPs are too high. Salt mixes nicely with warm water.

We set our pool up in May, 2014 and it is now July, 2014. We have not had to add any salt. It is my understanding that the "low salt" light will come on if needed. Very happy to say our pool has tested perfect each week and we haven't had to do anything except the usual Regular Filter changes. Absolutely nothing with the saltwater filter!

Please take some time to read the documentation. Fill the footbath with tap water ONLY and get all connected. While running add the salt VERY slowly pausing between sprinkles giving time for the salt to register (This isn't instant coffee). You added too much salt and the only way to bring it back to 2.5 or lower is to add water (dilute) whereas starting over would be more productive. Again read the documentation....

Yes, it may fix the problem if salt concentration reading is inaccurate. The switch also measures and conveys salt concentration along with being a flow switch. First, verify salt concentration is inaccurate by taking sample to pool store or buy test strips. Next, be sure the meter has no build-up internally (acid bath directions to clean found with internet search). In fact, the reason I replaced mine was because the salt reading was inaccurate (low by 1300 ppm and getting worse on a weekly basis). Note that the life of this (and the original) is only 1-2 years, at least for me. I have replaced mine twice. Yes, it may fix the problem if salt concentration reading is inaccurate.

I do not know. I only use this and a mineral stick and my spa is crystal clear.

That is exactly what I did, and it works just fine. I spoke with an employee at the pool store and he said there should be some chlorine in the pool. The system will maintain levels. So far I have been quite happy with system. Make sure you buy a water conditioner, so calcium doesn't build up so fast on the salt cell.

Sorry very hard typing on my phone. But hopefully you understand. I love my salt water setup. I don't mess with any real chemicals.

Apparently u have to drain it. Depending on how high the salt content is I just up the chlorine production to use more salt. Hope that helps,

I used bags of salt from Walmart. It was Morton pool salt in the garden section. It was on sale at 3.99 a bag, about $2.oo off the regular price at the time. The amount of salt depends on the amount of water in your pool. There are charts to help you with salt amounts in the instruction manual. Also you can test and check with test strips to see if your system is working right or you need ajustments.

No. If flow light is green, the switch is good. Test water with a salt meter or take a sample to a pool store and have it tested. Also be sure the chlorinator is clean, no calcium build up. Remember to never unplug or plug-in chlorinator when powered up. How old is your chlorinator? Salt level needs to be at least 3500 ppm.
