Taking over an inherited GREEN Pool

[ransomedbyfire]

Sorry I didn't post more info. I wasn't sure when I gave the info at signup where it was going to go.

What are the ingredients of the powdered shock?
Trichloro-S-Triazinetrione and inactive ingredients

What is the size of the pool?
4,400 gallons (4 x 15 ft.)

What is the source of your fill water --- a well or city water?
city water

How long ago was it filled? Why did it turn green if it was just refilled?
Last winter, when it got too cold to use the pool, my mom apparently just left it there, filled, uncovered, and probably untreated. Then, she died unexpectedly in January. Nobody really knew what to do to take care of the pool, and there wasn't much incentive to since it was too cold to swim.

A few weeks ago, my sister came by and emptied the pool, thinking she was going to take it to her house. But a relative offered to buy her a new pool instead. So, we refilled the pool.

By the way, according to the test strips, the pH is now correct.

If it's green now, and just 4,000 gallons, it's probably best to make sure you have the stuff to follow the Super Simple Recipe, and then when you do, drain and refill it. The small filters on Intex pools mean that the pool will stay cloudy for weeks even after the algae is all dead.
