Newbie needs help with Algae

[Simmons99]

hypo-cal will also add calcium to your water in addition to chlorine. It will be fine to use as long as your calcium level is below 500ppm.

Knarf:
Go to each forum and look for the stickied posts at the top. There are some for newbies, some for the B-B-B method, and some for the basic rules to clear algae.

The bottom line--all that junk the pool store sold you to toss in was mostly worthless.

What you need to do is:
1) Raise you Free Chlorine level to 15ppm and keep it there, checking 3x/day that it's up there and adding chlorine as necessary. For now, use regular or ultra laundry bleach--Liquid Chlorine at the pool store is the same stuff. Don't use anything else. 1 gallon of regular (5.25%) bleach will add 5.25ppm of FC to 10,000 gallons of water. 1 gallon of Ultra bleach (6%) will add 6ppm of FC to 10,000 gallons of water. Figure accordingly for your pool's volume.
2) Make sure your pH is between 7.0 and 7.6, but 7.2-7.6 is better.
3) Run your pump 24/7, backwashing whenever the pressure rises 5lbs.
4) Vacuum and brush your pool every day. Vacuum to waste, not to the filter.
5) Be patient. This WILL clear your pool, but it takes time and persistence. Don't add anything else.

It will work, but you have to follow these directions.
