Teja, in answer to your ? 'will adding borates to the pool absolutely prevent the algae,esp the floating clumps or strands?' The answer is
NO! Just a couple of hours ago I opened a pool which had a thin coat of algae on the bottom and the clumps floating on the surface (however the water was crystal clear). The homeowner came out an asked why the pool was green when he had paid extra to have the 'oxygen out stuff' (ProTeam/ borates) added to the pool. On the other hand,
his water tested 'ballanced', which with over 1' of rain in the past 2 weeks, was a little supprising

, other folks we've opened have needed to increase both pH and alk. (Can't even do an "f-test" [statistics speak] on this 1 sample, but perhaps it does help the pool, even if it doesn't fully keep the algae at bay, and last year the pool was much further to the 'swamp side' of green than this year [and he opened 3 weeks later this year] and other pools without the borates have been much worse)
However, I'll still refer to them as Pro Tease til I get some straight answers
