I have the newest model of the saltwater system the CS8111.ITs the one that adds copper to the water as well as chorine.It has worked fine for about 6 weeks.Now when I press the Boost button to add copper the units just makes a beeping sound and the 80 code number does not appear as it should.Does anyone have an idea why this happening and how to solve the problem?

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....

I have an Intex Krystal Clear Saltwater System, model CS8111. My problem is green water. I had been out of town for a few days and when I came home the pool was green. Also the low salt light was on. I...

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.

A sequestrate from your pool supply can prevent problems from the copper. The water you are adding needs to be checked for copper and algaecide especially for mustard algae will have copper. Diluting it with a water chance is the most common way to take care of the problem.

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.
