Hello,

You have an algae bloom. You are going to need to SLAM the pool. But I will need more information before I can help you further.

1.What type of pool? Above ground or in ground?

2.If in ground is it a vinyl lined pool, a gunnite/plaster pool, a fiberglass pool?

3.How many gallons of water does it hold?

4.How do you normally sanitize the pool? Chlorine granules, tablets, liquid chlorine, salt water generator?

5.What is the normal chlorine level you try to keep in the pool?

Please provide current readings for the following:

free chlorine 

total chlorine or combined chlorine 

total alkalinity 

ph

calcium hardness 

CYA/stabilizer 

Thanks

Get some fresh numbers. Because your pool is gunnite/plaster the calcium hardness reading is very important. And the CYA/stabilizer reading is critical.

 If you got the chemical readings from a pool store they had to have a water volume to compute them. So ask them how many gallons of water they show for the pool volume.

Please po the complete set of readings when you get them.
