Considering SWG

Fugacity · 2025-05-02T11:21:04-0400

After (over) thinking a diy automated liquid chlorine injection system, I've come to the conclusion that switching to SWG is pretty clearly a better idea.

I'm looking at circupool RJ45 for my ~20k gal pool (details in signature).

Is the 45 a good choice? Is going bigger better? Other options, hints on installation etc would be helpful. I'm an engineer, and competent in diy plumbing, electrical/automation etc.

Thanks in advance

Yes. No.

Think about how to control power to the unit so that it only runs when the cell runs.

F,

The 45 will work, but bigger is always better when talking a SWCG.. The bigger it is, the longer it should last, at least in theory..

I am not all the familiar with CircuPool SWCGS, but you need to make sure you can adjust your output by 1 or 5% increments.. I think some of their cells can only be adjust by 20% increments, which is not ideal, in my mind.. Double check the adjustments before you buy any cell.

Thanks,

The adjustment on the RJ series is 5% increments and works just fine.

Discountpools.com usually offers an RJ45 upgrade to a RJ60 for $10 and that would be a smart move. And yes, a SWG is clearly a better idea than liquid chlorine or tabs. Tabs = bad.
