Well,hi from Edie in Michigan. I bought a Summer Escapes 16 by 42 quick set type pool a few years back and finally got it up this summer about a week before July hit. It was great for the first week, then I got sick. While recovering I tossed some bleach in the second week, and this week, well you can just about guess what its like. Its a mosquito larvae fest. I don't have a skimmer and I am pretty sure the pump for this pool is less than adequate. I put 96 oz of Clorox and a box of baking soda in today, but I am guessing I should start over again. I don't have a pool test kit yet and I just dragged my vacuum (the type that adds water to the pool) out of mothballs. I was really surprised to learn the BBB, and it saddens me a bit. I had a nice above ground pool about 13 years ago but I had to let it go because of the cost of the chemicals ( I thought). Anyway, thanks for a great site with lots of information!
