Opened it up 2 weeks ago and it stayed green for 10 days despite "perfect #s" according to the pool store. I added Polyquot 60 and kept shocking it with liquid shock and bleach , finally after replacing the valve in the filter because of air bubbles and then adding Proteam mustard and black majic(Sodium Bromide) it cleared up but now the chlorine levels are really low. I just got an analysys at Leslies Pool Store and here are the #s. The water is clear but not sparkling yet.

16x32 inground vinyl
sand filter
FAC .5
PH 7.2
TA 80
Calcium Hardness 80
CYA 35
TDS 1000
Copper/Iron 0
Phosphates 500

That's all they gave me but they recommended I add
a bag of Powder Shock and 20lbs of Calcium Hardness(I didn't buy it) as well as phosfree anf 10 oz of PH up
Before I do anything I wanted to check with you all.
thanks from Long Island !!!
I'll BET they tried to sell you Calcium and Phosfree! Don't waste your money. There is no such thing as "low calcium" in a vinyl pool. You don't need it--it's only for concrete/plaster pools. Phosfree is the latest gimmick to move $$$ from you to them. You need to raise your FC to at least 3-6ppm if your pool is clear and you should do it with bleach or liquid chlorine. Your pH is a little low but with a passel of kids splashing it it, it will go up enough.

Forget TDS--if you had an SWG your TDS (from the salt) would have the pool store guys DROOLING over stuff they could sell you.

In short, you need chlorine but otherwise GO SWIMMING!
