If your CYA is high, you URGENTLY need to raise your chlorine level. Hopefully, you'll be able to do so before algae gets established in your pool.
1. Get a local cheap OTO / phenol red drops test kit (Walmart, etc) and add chlorine till you read the DARK yellow range on the kit.
2. Order a K2006, so you can actually determine what your chlorine level should be (10% of your CYA level), and keep it there. http://pool9.net/tk/ Be sure to watch the videos before you use the kit. Ignore the booklet that comes in the kit.
