These units are very new to the market. The Manual Provides useful info where codes are concerned.Could be a Salt issue. Although I'm not as familiar I'm sure you can look the code up in the manual for an explination or contact INTEX at

My water is cloudy and says low salt. I added 120 lbs and it still beeps low salt. I have a CS8111 saltwater system & filter combo. It is on an above ground pool 24' X 52".

Check the electrolytic cell!!! You will get a low salt alarm if cell has calcium or sodium build up.. If it does, soak, flush and clean with vinegar.. Also, make sure you run the pump only, no chlorinator for 24 hrs to properly disolve the salt you just put in....

If your salt is at the correct levels required for your pool and your still getting the "91" code on your LCD screen do not add more salt you need to clean the plates on the chlorinator. Look at your manual and it gives you instructions on how to remove, clean, and replace the chlorinator section on the pump. Reminder, if your PH and/or alkalinity levels are off you'll be cleaning the plates often because of the scale build up. I personally run my pump 4 hrs daily and I have never had a problem with green water however, once it did become cloudy (white) I began treating with algaecide and changing filter every 3 hrs. It cleared it right up. I love the Krystal Clear System.

I'm not sure about an Intex saltwater system, but you don't want the copper levels to be too high. This can cause staining on the pool liner that is difficult to get rid of. I'd recommend taking a water sample to a local pool store and have them check all of your levels. Since the chlorine produced by a salt chlorine generator is unstabilized chlorine, you need to make sure you have the cyanuric acid levels within the proper range. This can be increased by adding stabilizer or conditioner.

Green water

Green water is indicative of copper in the water ... let the CL go down (the lower the better) add a sequestering agent according to package instruction ... then introduce CL again.

Conversely, the filter will eventually take it out.
