Pool green and out of balance

[PoolDoc]

To follow up on what Carl said:

1) You should not do *ANY* of the things the pool store told you to do, at least not now. Instead, add 4 gallons of plain 8.25% household bleach EACH EVENING (not: morning or midday) until all the algae is gone.

2) By the time that happens, your friends K2006 kit should have arrived. Report test results, using that kit.

3) We have very limited patience with 'relay pool care', where a 3rd party (you!) keeps running between us and the pool owner. It's hard enough, helping with pools we can't see. If you don't have authority to act, have your friend register.

I agree with Ben:

BTW, if your pH is 6, there is absolutely, positively NO WAY you should add pH Down! That's a powdered acid and the pool is already seriously acidic! You do NOT want it more acid. If you goofed and it's actually pH Up! they recommended, then you should know that Arm & Hammer Washing Soda (in the yellow box in the laundry section) is EXACTLY THE SAME CHEMICAL as pH Up!

BUT---as Ben says, what you NEED is chlorine, and that is easiest to add by adding plain, unscented, bleach. And, without proper testing, anything else will mess things up AND none of the things they told you to add actually kills algae.
