Opened pool and problems...

[chumpy36]

I opened the pool this year a bit late and discovered a pretty nasty mess of algae underneath the cover. It was mostly brown and pretty disgusting..



I have a Taylor K-2006 on the way but right now I just have the more basic taylor tester.

30k gallons
Vinyl
Dichlor granulated shock in 1lb bags
I have been adding it each day in recommended dosage (3 lbs)
unknown (my k-2006 kit is on it's way)
Unknown
I have added clarifier
Sand filter

Thanks for the reply. I'll have the pool store test water tomorrow for the missing info...
