I'm paying about $76/month for a chemical only pool service. The price doesn't bother me but, my pool is green about 30% of the time. After reading about the BBB method I'm considering trying to take care of it myself again. So I need to buy a quality test kit, the cheapest bleach I can find, some borax and baking soda,read a little bit and I should be good right? Is it really that easy?
