OK... so two years ago the price of a g35 nature-2 cartridge went over $100 around here.
This got me to thinking: whenever my chlorine drops to near zero the pool gets cloudy, so what is the nature-2 doing for me?
Last year I got a g-35 for $80 and started reading about bbb pools.
This year I did not buy one, and I have the chlorine around 1.0 and all is well.
What I am reading tells me I need to have my chlorine levels a lot higher. What risks am I taking by leaving chlorine around 1.0 without having a nature 2 cartridge?
