Because I have an ozone system can I have a lower FC?
Does the TFP SWG calculations for pool chemistry take this into factor?

ozone system and FC

No. Ozone systems provide no sanitation and extremely minor supplemental oxidation. It does not change the recommended levels.
Without a significant bather load, such as found in a public or commercial pool, the supplemental oxidation ozone provides is wasted. Not to mention residential models tend to produce minimal ozone to begin with.

m,
My question to you is why would you want to lower your FC? What are you expecting to gain? You have a SWCG, which already allows you to run a little lower than when manually adding chlorine.
Thanks,

First let me say thank you for this site and forum. This is something I was told when I was "pool stored" and lost in the weeds with my new pool. Everything I have read here is helping greatly and I want to clear this up for my own education.
Another "pool store" myth...."never add Baking soda to a pool with a SWG"
I've been lost listening to them for 2 months and decided to go it alone and cant thank TFP enough for helping me!

Mark,
Adding Baking Soda will increase your TA... That said, most people have the opposite need... their TA is too high and they need to lower it.
We generally advise pool owners to maintain their pH anywhere between 7.2 and 7.8 and not worry about TA unless it tries to go below 50... With a saltwater pool, your pH is much more likely to want to stay at about 7.8, so adding too much MA, to drive your pH down to 7.2, can cause your TA to fall too low...
Oh... thanks for becoming a Gold Supporter.. it is one of the main things that keep this site alive and helping...

Jim,
Here is my recent test from the pool store. Don't worry I learned my lesson and ordered the tf-100 today
FC: 4.7ppm (1-5ppm)
TC: 4.7ppm (1-5ppm)
CC: 0 (0-0.9ppm)
pH: 6.7 (7.2-7.8)
Hardness: 277 (200-400ppm)
Alk: 5ppm (80-120ppm
CYA: 31ppm (30-50ppm) note my owners manual recommends 80ppm. The FC/CYU chart is 70-80 I think.
copper: 0ppm (0-0.2)
Iron: 0ppm (0-0.3
Salt: 3500ppm (2800-3500ppm)
due to the low TA I have added some baking soda. also, some CYA. and ran the pump on high to circulate and aerate.
ill check it again tomorrow. thanks

I am not one of the great chemical experts here, but I have never heard of TA being 5 ppm... I do know for sure that your pH of 6.7 is very low and needs to come up. Aerating is a good thing when you have low pH...
Just don't go back to the pool store any more...
Your TF-100 will be there soon... and we can see what your real numbers are...

I'd be on that pH like white on rice. You need to get that in order to avoid problems. Can you take some water in to a different pool store and get their take on the pH and TA. Then tell us what is up.
Have you seen PoolMath yet? Find the link at the top and play around with it a bit. It will be a huge factor in keeping your pool up once your own decent test kit arrives.

Thank you all for your advise. I'm going to get some test strips till the tf-100 arrives.

Don’t waste your money on the test strips. They’re horrendously inaccurate, even worse than store testing IMO.
You've gotten good advise above, so I'll just chime in about the pH and TA. pH is one of the things that pool stores aren't usually too bad about getting wrong, so I'd tend to believe that number. All the rest of their tests are pretty subject.
The easiest way of getting your pH up when your TA is low is to add Borax. Looks like you'll need about 2 boxes of it.
Since we don't really believe the TA, I wouldn't worry about it until you get the TF-100 kit.

To All,
Great results from yesterdays intervention!!
FC 4.0
CC .07
pH 7.9
Hardness 373
TA 91
CYA 67
Thank you all so much and thank TFP for this site. Cant wait for my test kit to arrive and fine tune as well as maintain a TFP.

What did you add? Did you add Calcium, add CYA? 22 pounds of baking soda? These numbers don't make sense it you were just trying to raise pH!! Don't bother going to the pool $tore for testing. You are not getting accurate results.
I turned the pump on regular speed with the spill and bubbler for aeration to raise the pH. Turned off the SWG. I added stabilizer and baking soda using pool math. held my breath and prayed. I agree the hardness is suspect.
Mark
Mark
They are all suspect to be inaccurate in my opinion, either the first set or second set, or both.
You are best served to just wait until your test kit arrives and add some bleach each day. I would hate to have you add unnecessary chemicals based on questionable tests.

I have a SWG. Why add bleach? My FC is actually a little on the high side and I turned the SWG down.

Got it. DUH. I was looking at the wrong chart. Turning up the SWG!
Thank you all,

OK, SWG it is, lol. sorry, I got it confused with another thread.
