Hi! I am new to pools, bought a house in the winter with a pool that I know has not been opened for at least 2 years. We opened it 2 weeks ago and have been shocking it. It started out with a lot of gunk in the bottom that we fished out and very dark green. Now it is light green, can see about 4 inches down into the water, can definitely see the bottom of the pool steps, running our filter 24/7 but it is not getting any better from the light green. I have brushed the sides and bottom as best I can. The pool is about 8 foot to 10 foot (not sure) at the deepest and I can't get that real well. Just tested and these are the results:
Total hardness is 250
total chlorine is 5
free chlorine is 10
pH is 6.2
total alkalinity is 40
cyanuric acid is 0
1. don't know how many gallons water - pool is 40 x 20 and from 3 feet to 8-10 feet deep
2. sand filter, don't know size - it looks big to me!
5. Don't know.
Can someone tell me where to go from here? I have ONLY put in liquid chlorine at this point and nothing else. Thanks!
