Is there a rule of thumb...

I guess I should have put my pool info in...12,000gal IG exposed aggregate surface. Cartridge filter...not sure what size. I don't know what type and size pump we have...the mechanics are more my husband's area

I can try to add pH chems in the AM if I can...I actually did that over the weekend, and it worked out quite well. I always add bleach at night...usually it's not much...maybe 0.5 gallons every few days. That's good to know I can let the pump go off at 8. If I end up having to add acid PM as well, should I let the pump run longer in that situation? I really don't like adding acid or chlorine to the skimmer either. I usually concentrate around the returns.

If you have to add acid at night, try to run your pump for at least an hour after the addition to make sure it gets circulated and doesn't concentrate in one area.
