SWG Settings

[natalieh]

Hi! I have a Jandy TruClear SWG that treats up to size 35k gallon pool. My pool is 20k gallons. We have been running it at 100% 24/7 because we haven't learned what to change the setting to yet. We decided to leave it at that setting while we focused on balancing the pool. I am now losing chlorine and my SWG says low chlorine.

Here are my test results (Taylor test kits):
Salt - 3400 ppm
FC - 1.0
CC- .5
PH - 7.8
TA- 210
CYA- 50

How would you move forward? I have salt and chlorine I can add but wanted some direction regarding the SWG first.

Do a Overnight Chlorine Loss Test

You are probably developing algae that is consuming your chlorine.

How does your SWG show low chlorine? Your very high TA could be causing the SWCG to be scaling up.

 

[natalieh]

I wrote that incorrectly. The SWG indicates low salt.

 

[mknauss]

I would check the SWCG for scale.

What is your current ch? That is missing from your results.
This is the max fc that your cell can produce in 24hrs in your pool

The average fc consumption in an algae free residential pool is 2-5 ppm/day give or take depending upon conditions so having on full throttle is likely necessary during the peak of summer.
As recommended above get fc to target range for your cya ASAP
FC/CYA Levels & do an
Overnight Chlorine Loss Test to see if algae is consuming your fc.

Check your cell for scale & see if that is the problem . If it has buildup use the least invasive method first before proceeding to more aggressive ones

Thank you. The CH is 1075. We have well water and it is very hard. We also have iron, which is probably affecting the chlorine (which I didn't consider).

Thank you for the additional links. I'll read those as well!

With a CH of 1075 your SWG is probably getting scale.

What is the CH of your well water?

Iron does not affect chlorine demand.

Do you use a metal sequestrant?

 

[Mdragger88]

Wowzers that’s high. What is the ch of your fill water?
Likely some scale going on the plates.
Here’s some tips to help manage your ch

The iron shouldn’t have any effect on your chlorine levels but here’s some info on how to deal with that too as It looks as if a water exchange may be in your future .
