The best way to use bleach is to just pour it in the pool in front of the return water flow. Every time you use a puck you increase your CYA level which in turn increases the amount of chlorine it takes to keep your pool sanitary, eventually you end up with algae that you have to really douse with chlorine to kill. And as far as algae goes, the only algaecide that the people here use has the word polyquat (sp?) in the ingredients, any thing else just puts garbage like copper in your water. Why not post up a set of numbers so that someone can guide you, also tell how big your pool is, how many gallons etc. Good luck, once you get going it is a breeze, I just dump in around a half gallon of bleach a day basically for my pool. Also around once per week I add about two cups of Muratic Acid to lower the Ph back down. It is that simple.
