For the OP...I see that you recently joined the forum...welcome...you probably have been doing some other internet research. In addition, you most likely have been getting advice from friends and co-workers with pools.
Speaking as someone who has "been there and done that," the information that you will get here is the ONLY source that you should trust. This is a time tested, "mother approved" method for pool water chemistry. The collective knowledge from the people that have answered your thread is 1000 times that of any other source. Chem_geek, duraleigh and waterbear (and others) are THE source for this information. They have no bias, no hidden agenda. The may disagree on occassion with each other on some esoteric details. But for your problem, trust them.
This is not vodoo or witchcraft. It has been repeated here a gazillion times (and you can read more at
www.poolforum.com for a longer history) about clearing algea. Maintain a free chlorine in the super-chlorination range (using the best guess tables), filter, brush, and time and your pool will clear.
Get a good testing kit...this is truly the key...post your numbers requently...and this group will get you a sparkling pool.
And...do not add any "algacide"...unless someone here suggests it...and if you have alreadly...let the forum know, because some of these products are less then helpful (and may make things worse)...
This is science...there is nothing to believe in...just have some trust...
Before you know it...your water will be like this...BBB FTW (for the win)
