    Replace IC40 with IC40 or...?

    Hi. I put in what I thought would be ballpark, knowing the chlorine level would quickly drop. And it did, as expected, giving me a starting overnight CLT. Today, I am monitoring and adding chlorine as needed to maintain 24ppm. After adding 2 gals this morning, I tested moments ago - 23ppm. The...

    Replace IC40 with IC40 or...?

    Just a status update. I added 8 gallons of 10% liquid chlorine to my running pool around 8AM with the pumps running full tilt. I waited a couple of hours and checked the chlorine level - 32ppm, overshot. By around 6PM, chlorine level had dropped to 24ppm. Water was murky but less green. By...

    Replace IC40 with IC40 or...?

    No - it has a drain valve I attach a hose to. Water was too murky to see anything, so I scratched the idea. We had rain predicted for yesterday (didn't happen) and more for today. On the plus side, I now have 24 gallons of liquid chlorine ready to get started.

    Exactly my thinking!

    Replace IC40 with IC40 or...?

    Well, since the water level is high (covering the skimmer intake), and there is algae coating the bottom, I thought about using a vacuum brush to vacuum out at least some of the surface algae. Might be useless, but it will make me feel better. ;)

    And the calcium and/or hardness? Is that any concern at this point? Thanks!

    Okay, here are the results: Daily tests - Chlorine - 0 pH - 7.2 Weekly tests R-0870 no or extremely light pink R-0871 maybe 2 drops so 1ppm R-0003 5 drops made it pink R-0871 2 drops made it clear so 1ppm Calcium test 625ppm Total alkalinity test = 130 CYA - 60

    So, don't drain anything, clean anything, leave it as is and run tests and post results? I can do that. ;)

    Replace IC40 with IC40 or...?

    So, TF-100 test kit arrived this afternoon. Water is somewhat murky. Algae on bottom and sides of pool. Just had heavy rain last night. Might get more tonight. As a result, pool is filled over the skimmer intake. With that said, where should I start? As is or what?

    Replace IC40 with IC40 or...?

    For the longest time, the cell was easy to maintain - it had a little scale most times, easily cleaned with a weak solution. Whatever happened recently, the "Flow" sensor malfunctioned (and it was physically damaged - the plastic stalk was split). I replaced that, and when I went to check the...

    Says 3300ppm and also CLEAN CELL!!! I don't know the actual salinity at this precise moment. Kinda hesitant to get it tested. In the past, Leslie's tested it @3400.

    The IC40 "Cell" LED is flashing. That's the only LED that's not normal. Everything else shows as okay. I just ordered a TF100 from Pool Supply World. Added another 4 3" chlorine pucks to skimmer. Pool water is clear but not sparkling/crystal clear. Surface algae on bottom, some on sides...

    Replace IC40 with IC40 or...?

    Hi guys, and thank you for the quick replies. Do I acid wash? Yes, with 3:1 or 4:1 solution depending on how it looks. I also used the descale stuff that's supposed to prevent build-up and, quite frankly, it worked well enough I had to clean the cell only occasionally. What % output? 100%...

    Replace IC40 with IC40 or...?

    Okay, so my 3-year-old IC40 is now blinking, and I'm a bit annoyed as this is the 4th cell we've had in 12 years (3 year avg life) for a 12000gal pool. A new cell costs another $500, but given the frustration I've had over the years with these things, I'm considering changing over to an in-line...
