Intellichlor IC40 not producing chlorine could be an indicator of an high salt level. My ic60 does not produce chlorine when it gets below 3000 and I had to recalibrate it before. Meanwhile it was reading green, with levels ok. But, it was actually 2600ish.
Intellichlor ic40 not Producing Chlorine
Assuming all indications are normal, after you have
- Tested and adjusted your water to the proper limits. You should get a K2006 and accurate salt strips.
- Made sure your temperature is above 70 degrees.
- Use plain 8% store brand bleach to bring your chlorine up to normal levels, and to maintain them for several days. THEN, see if the SWCG can keep up.
If all of these fails then you should reach out to the company.
Intellichlor Ic40 Not Maintaining Chlorine
Algae in the pool consumes chlorine at fairly quick rates. Even if the water is clear, there might nascent algae that is not yet visible that feeds of chlorine. The fix to this is to shock the pool with unstabilized chlorine, usually chlorinating bleach or liquid, and maintain the shock level until the overnight FC loss is greater less than 1PPM.
A reasonably fast shock level when the CYA is at 60 ppm is around 24 ppm FC. Basically, when shocking a pool to kill algae, you maintain a high chlorine level not only until the algae is no longer visible, but until you do not have substantial overnight chlorine loss.
Secondly, you should check your filter and backwash it (or clean it as appropriate) since there may be some dead algae in it getting oxidized by chlorine.
Once your pool has been shocked, note that you MUST target an FC in an SWG pool of at least around 5% of the CYA level.
For a 60ppm, that’s 3 ppm and for 80 ppm that’s 4 ppm. Please note that is crucial for your CYA reading to be accurate.
I recommend using a Taylor K-2006 test kit (BUY ON AMAZON) since its results are accurate and precise. Your FAS-DPD chlorine test can also measure within 0.2 ppm for CC and FC (using 25 ml sample; within 0.5OOM using a 10ml sample) and does not bleach out at high chlorine levels.
