Sustain from PPG - Should I switch

[UNITY520]

Last summer, I felt like I was loosing the battle to my pool.

I work during the week and wasn't able to properly treat the pool. This year I switched to sustain. Once a week I pop in the chlorine tablet and stabilizer and so far my pool has been crystal clear.

I have an AG 12x16 pool and use a cartridge filter. I run my filter 2-3 hours in the am and 2-3 hours at night. The best think I did was switch from the cheap hoses the pool store gave us to a flex pvc hose. My return water has been stronger this year then all of last year.

Sounds like you've got it under control.

Why don't you master using the test kits this season, and then -- if you like -- switch to a cheaper source of chlorine next year.
