John,
**** EDIT my cut and pasting errors made it to where this didn't make sense. Now fixed****
Now we're starting to get more information the picture is becoming clearer. TFP methods are pretty simple and very effective. They rely on simple tests so we start with accurate information then we use simple tools to figure out what to do that results in a perfect pool at the cheapest cost. Here's what we know:
- Pool size
- swg brand, model - this tells us you are supposed to make 5.3 ppm in 24 hrs at max conditions
- Your logs indicate you've had way over 5 ppm but you don't have logs frequently enough to really diagnose. The FC levels indicate you must be doing something in addition to run your swg that raises the FC.
Here's what we don't know:
- What are your settings
- Daily test results for a few days
- What else are you adding?
- How old is your swg?
- How are you testing salt?
If it were my pool here's what I'd do:
- Raise FC to 9 ppm with LC (see chart clip below)
- Turn swg on at max and run 24 hr
- Check FC, CC, pH
- Report the numbers here
- Fill out signature so we don't have to read through all the posts to find out basic information about your pool. Our volunteer experts only have so much time available. This gets you answers your questions quicker and helps them be productive with their volunteer time. It's simple, here's how.
- You'll get advice on the next step quickly right here.
Your cell is too small for your pool but may work for a year or so, especially at your location up north with relatively short season as
@Jimrahbe mentioned. Cells degrade over time so if your cell barely keeps up to start with it will degrade to the point you need to add LC which sort of negates the benefit of swg. So we recommend 2x size. I only know of two that make the enough. Circupool and Pentair as
@PoolStored mentioned above. Eventually, when yours doesn't produce enough I would switch to one of them. Automation systems figure in to this decision a little but in my opinion it's not very leveraging. If you buy the same brand swg as your automation you can control % power and run time. In your case there's not an swg available that will make enough FC so it doesn't really matter. Yes, you can run two but that's unnecessarily complicated and expensive. You don't need to change % power that often. You should be able to get by with max power and adjust run time only
unless You and you can do this until you start needing more FC than your unit makes. Then buy one of the 60 size units and set it up with run time control only. You can use your existing system to do this if you have a spare relay and most installations do. You'll have to set % power manually but that isn't usually required more than every year or so. I'm in a similar situation where I need the largest size. I bought a Circupool RS 60 because it was the best price/# chlorine at the time. I'm ambivalent on brand since my automation doesn't control % power on either and both of these have good warranty, reputation here.
I hope this is helpful.
