1). ProTeam=Borax=ProTeam=Borax.........(Borax is cheap, ProTeam is not)

2). According to the bleach calc, that would give you almost 100 ppm Tetraborates, or twice as much as "recommended" on this forum. Unfourtunately, there's a lack of good data around the algecstatic properties of high concentrations of Tetraborates in pool water. People use it to increase pH without increasing Alkalinity, any other benefits are considered a bonus. Do a search for Borax here for all kinds of good info....

4). On Pool Solutions, Ben offers his thoughts on algecides here: http://www.poolsolutions.com/tips/tip08.html

Sounds like you've come very close to being "Poolstored"!
