Hello. Have been using walmart pool chlorine. and like it it's like 5.50 a gallon. But they put all the pool stuff away for winter. Way too early in my opinion. So I have been looking for plain bleach without fabric softner. Couldn"t seem to find it. So I went to ocean job lot. and bought some of there pool shock. The liquid stuff. active ingredient is sodium hypochlorite, 20 bucks a bottle. is this stuff ok to use? I also bought some powder HTHpool care shock cal hypo shock. it says a 6 pack. it says to broadcast over the surface of the deep end at the end of the day. When people our done with the pool. is this stuff ok ? I don't want to shock the pool. Just want to keep it sanitised. I thought i could take one packet and use a small amount of it? Or pour a little of the liguid stuff then check my chlorine level in a few hours. What do you think? Thanks ahead of time. filix.
