A typical pool looses about 2 ppm per day of FC, 3 ppm is on the high side, usually a sign that something may be starting to try to grow, but for safety sake lets use 3 ppm per day as your FC consumption.
Pool math tells us that for your pool this would be about 54 grams of chlorine gas for a 3 ppm rise or 36 grams to make up for a more typical 2 ppm per day loss.
The above mentioned 12 gram per hour intex SWG would need 3 hours of run time to produce a 2 ppm rise in the pool, which fits fairly nicely in the 3-4 hour per day required runtime for filtration. This may mean needing to run the pump longer than the runtime on the SWG.
Alternatively you could get the 5 gram per hour SWG and plan on 6-7 hours of pump runtime per day, which will likely give you excessive filtration to reach your FC daily goal. Either way works although running the larger SWG fewer hours per day will likely extend its useful life.
