First time opening pool since joining this forum

Okay. Read CarlD's excellent post here: http://www.poolforum.com/pf2/showthr...You-have-ALGAE!!!

Towards the bottom it talks about algae and the importance of brushing, etc.

Get the crud out ASAP as it will use up your chlorine as fast as you put it in. Your high CC proves this.

Bring your FC up to 15 and keep it there, not letting it drop below 12. Keep your pump on continuously.

If adding 1/2 gallon of 8.25% brought you to FC of 4, your pool volume might very well be less than you think.

A green, cloudy pool would not be clear by this weekend anyway; it will take a while, sorry.

Stock up on bleach, Taylor reagent R-0871, and patience.

Let us know how it goes and if you have any other questions. Wishing you good luck!
