First off, hello to everyone on this forum. I just stumbled upon here and I wish I would have found this plethora of information long ago!
For starters, the pool is located in the San Joaquin Valley of Northern California. I have an in ground 22,000 gallon gunite pool with a DE filter, with a single skimmer, that has inevitably turned into a swamp over the previous winter. It has been swampy green since late September of 2010 after my Polaris 360 was stolen from the pool and I slowly ignored it and it's need for chlorine. I know the basics of pool maintenance but my source of knowledge may have not been credible so I am hear to start fresh and get on the right track.
Earlier this evening (before I had found this forum) I netted the floor and surface removing most of the leaves, it wasn't as bad as I thought at that bottom of the unknown, just a small layer of muck and leaves. I threw in 2lbs of Chlor Brite shock (99% Sodium dichloro-s-triazinetrione dihydrate) and added 3 pucks to the chlorine floater. I then turned on the filter manually with intent to run over night and scrubbed the walls and the shallow end floor. My plan of attack after that was to add 64oz of Kem-Tek green algaecide (30% poly ethylene) tomorrow, which I have already purchased, and scrub in the morning and allow the pump to keep running throughout the day. I'm basically hoping the chemicals with clear everything up so I can clear out the rest of the debris with the net and vacuum and then take my water into the Leslie's Pool and see what they say to do.
After reading some posts here I went and looked at my pump and found out it is a Pentair Nautilus NS-60. I also found a basic pool test kit and checked my water 2 hours after adding the shock:
Cl - 2
Br - 4
pH - 6.8
I have read that I will need to get a better tester and I will see if they have one locally asap. I'm basically wondering if I'm on the right track to clearing up my pool and am completely open to any advice or instruction. I would also like some help figuring out how to backwash this beast. I can take pictures of anything you need to see and plan on uploading some when the sun comes up. Thanks in advance for the help!
Additional info: Last winter the pool became swamp like and being a new pool owner I hired a pool cleaning company to come correct it. They drained it, acid washed, and talked me into allowing them to cut off the pipe that goes to the other mini filter (can't remember what it is called) so that if I backwash it all shoots out right next to my filter. After they got it back to clear water I kept it maintained over the summer by simply keeping chlorine in the floater and shocking when it got cloudy. The filter is currently running at about 27psi. The lever that I assume you turn to set to backwash position only turns a small amount clockwise to a position labeled "open", otherwise it is "locked."
