SWG - is the Intex brand good for a 6000 gal above ground pool?

Was thinking of adding SWG. I currently use 25-30oz of 10% LC a day. Was looking at a Intex Krystal Clear™ Saltwater Pool Chlorine System - 15,000 Gal. I did find some really older posts on here that said they were decent systems.
That system produces: Chlorine output 12g/hr. How do you convert grams to a number I can compare to my LC use? My pump is 1500gal/hr so I run it 6ish hours a day - wondering how much it will produce in that time frame.
I have tried to read up on it. I will need to lower my TA (140) and raise my salt level (I added some salt to water already for a better feel).
In pool school it mentions FC of 3-4. Will the pool use less chlorine with lower FC numbers?

Sorry lots of questions. But I did donate!

We usually advise folks to obtain a SWG that is at least 2x the size of the pool. I don't know this brand but it looks pretty good to me. Check it out if its better priced than the Intex brand-
ChlorMaker SWG
It says it makes 30gm of chlorine per hour.... gotta get a math whiz to figure that out.
You need to obtain the Taylor K-1766 Salt test kit. If you do need to lower your water level perhaps it will also lower your TA. The TA is the last chem level we worry about as it mostly just affects how fast your pH rises.
Your CYA level will need to be a bit hgher - ideally 70-80ppm.
The SWG works slowly but consistently so it works better than other ways of chlorination. Follow the CYA/FC Chart for how much FC you should strive for. FC/CYA Levels

Converting grams to ounces, the swg will produce 10.1 oz of chlorine gas per day. In a 6000 gallon pool, that would equate to 12 PPM of FC per day, if run at 100% 24/7.

When doing calculation in Pool Math for SWG production/targets, select "Chlorine Gas" from the pull-down menus.

Thank you!
So you convert grams to ounces which gives you a number you can use in the pool calculator (chlorine gas)? Currently am using 27 ounces a day - FC drops from 7 to 3.5. Pool calculator shows that would be 2.8 oz of Chlorine gas. Which would be 79 grams?

Also - does a salt water pool use same amount of chlorine a day? Or does less burn off due to lower FC numbers used.. 3-4ppm instead of 7-8ppm @60CYA that I am at now?

Sorry for all questions....

Looks normal for daily FC loss.

Higher CYA levels (as recommended for SWG pools) result in less FC loss.
