Test after opening salt pool

[paul1971]

It is best to always run the SWCG while the pump is on.
some like to run 24 hrs and produce a little chlorine at a time throughout the 24 period
Others may run the pump for 10 hrs (example only) but the SWCG is on the full time the pump is on.

If you have Pool Math app, go to top left (hamburger menu) and select Effects of Adding. Ensure the pool volume is accurate, then select your SWCG model. Pick either pump run time or % output or desired FC to be calculated and put data in for 2 of the 3 which solves for the 3rd.

Thanks! I set the t cel at 5 but i could do 3, output at 30 is about 1 a day.i’ll monitor and see. I think i screwed up FC test yesterday. But i am now clearer on swcg lol

I used your pool data of 11k gal and T-9 cell. If pump run time is 12 hrs and SWCG set at 30% output, the FC generated is 1.6ppm over that 12 hr time frame. That may be fine for this time of year in your area. If you only want to make 1ppm of FC with SWCG set at 30% then the pump run time is 7.5 hrs. You should test every 2nd day as a minimum.
Post a full set of test data.

FC 6.5
CC 0.5 ish
TA 50/60
Ph 7.8
Salt 2400/2600
Based on all charts pretty good level i think. Cya have not test but assume stay at 40
Thanks

Looks great. If your salt test is with drop method then it may be a little low for your SWCG. Most SWCG range from 2800 to 3800 depending on model, make. Your SWCG may be reading a higher level of salt which is fine - but it is best to monitor salt using the drop test as compared to the SWCG reading or use of salt strips.
A 40 lb bag will raise salt level by 435ppm.

I find it so difficult to precisely measure salt….i use drops and follow instructions but find it difficult to judge exactly when the color turns from brick to red. I find that it turns redish right away and does not go thru salmon-brick color. Also, i learned not to trust the swcg reading (it says 3200…) and also pool store results. They use the machine to test salt level and i went the other day they said 2800…not sure if i should just dump in 40lbs to be sure or not. I opened the pool on may 1 and half pool was rain water and have not added any salt at all this year….thoughts?

40 lbs would put your reading close to 3000 and the pool store a little over 3000, while the cell was still under 4000. Everybody wins. Its not going to go up on its own and the spring has been awfuly wet so far so it'll probably continue to drop more than normal.

Sounds like youre not using a smart stir. It really makes a difference for salt.

I use the smart stir from the pro kit i bought thru this forum
Ok i’ll dump in a 40lbs bag then…

OK sweet. I often wonder how tricky it would be by hand as most drops flicker it red. But I wait a 1/2 second and it keeps going back to yellow-y milk. Then, BOOM. There's no mistaking that one. Lol.
