Returned home from running errands and the pool is less cloudy than this morning! I can see the bottom again. My husband was going to start to vacuum...is that the next right step?

Once we get the Cl level using bleach to 15ppm is that where we should always keep it? From then I tackle the other levels?

So today...Should we add just one more gallon or two again? Someone replied back that we will add approx a gallon every 3 days but that was said I believe for when this is all under control.

Also can we only add the bleach at dusk or can it be added anytime?

Regarding that testing kit - is the kit only good for one season? Here in WI our pool season is pretty short. Researching the kit it looks around $75 but sounds like it could take a month to get here. Just not sure if it seems worth it to buy this season???

And of course the most important question...when will the pool be ok to swim in?

Oh and one more thing...Watermom - what did you mean when you said I don't have bromine? I just was typing what was located in the testing kit so I just put it on there. Is it on the test kit for another purpose? Do other pools and I just don't? Just trying to learn more...
