Chlorine tablets that don’t affect CYA

[SorryImaNewb123]

I don’t use Chlorine tablets anymore because it makes keeping track of my ideal FC too difficult, due to CYA always increasing.

I use liquid chlorine, but it’s a lot of maintenance as I’m trying to avoid dumping in every 1-2 days.

Are there any tablets that don’t increase CYA and just increase FC? If not, should I just invest in a SWG instead?

There are cal-hypo tabs. They are very expensive. They have the same problem, CH can only be removed by replacing water.

Get a SWCG and don't look back.

Thanks for the advice. Is there a SWG that you would recommend?

Circupool RJ60+ if you don't have or don't plan to add automation.

You need a reliable test kit as well. Test strips are inaccurate and unreliable.
The TF-Pro Salt would be good if you are adding a SWG. Test Kits Compared

Thanks for the advice! So for SWG I would need to replace the cell every 5 years or so? How much do they cost typically? Our pool is only open 4-5 months each year as in NY.

Circupool is rated 15,000 hours. I don't believe it, but I do believe 10,000 hours is reasonable. I have the RJ60, I use the equivalent of 500 hours per year. I expect, baring physical damage to get 7-10 years.

Your pool is 30% larger and in a general sense, the same latittude. I'd expect you will use about 650 hours per year if you use a solar cover. If not, it might be 1000 hours per year.

The biggest/best ways to maintain a cell are to 1) keep your CSI slightly negative, between -.3 and 0. Raise and maintain your CYA 70-90 (reduces fc demand). I also use Borates, which lowers the pH in the cell. My cell is 3 years old and clean as a whistle. YOY output has not diminished (I use the same % this year and last year during comparable weeks).

Very helpful! How do I reduce or increase CSI? Any other common mistakes people make with SWG?

The biggest mistake people make is unnecessarily using acid to clean the cell. Manufacturers usually recommend a scheduled acid bath to keep the cell free of scale. Muriatic acid strips the SWG plates of the rare metals required to generate chlorine through electrolysis. This unnecessary practice shortens the life of the cell. TFP believes that proper water balance will eliminate or reduce scaling within the cell. If scale is present, we recommend using different techniques before resorting to an acid bath.

pH, TA, CH and water temperature have the biggest impact on CSI. When you lower each one of these, it lowers CSI. FC, CYA, Salt and borates have very little impact on CSI.

Here is where I run mine. Enable CSI and Temperature tracking in Pool Math, then you can play around with changing your parameters to get your results.
