EDIT 6/5/19 - Please view the first few pages as a lesson in what NOT to do. Results did not start happening until I started going this right. Pool stores will give you lackluster advice and chemicals that won't get you anywhere. Also make sure your filters actually WORK!
I recently bought a house with an in ground pool. My girlfriend decided she wanted to pay to have a pool guy come out since neither of us knew anything about the pool, equipment or how to open it. This pool has not been opened in at least 2-3 years I'd estimate, the former owner was an old lady and her husband died a few months before she put the house up for sale last October and we bought it in March. It had a tarp on it and while the tarp was secured there was a bunch of leaves in it. It has since grown a Crud load of algae and I leaf raked as much as I could without being able to see more than 6 inches through the water. The pool is inground with a Hayward EC65A DE filter.
Pool guy comes out and we had been filling the pool as it was just below the skimmer when it was last closed, since we're on well water we'd fill it about 2 hours a night to get it halfway up the skimmer. The pool guy came out early and dumped some chlorine in the pool and algaecide and said he'd come back out once the water level was halfway up the skimmer. During this time I learned more from Google and doing my own tinkering than this guy could teach me, even though she paid him $200 for this service. I learned how to take apart and clean the DE filter, how/when to bump it, how to add DE, how to clean the pump, I brushed the sides of the pool to loosen up the algae etc.
Once we got the water level up he came out again and added 4 gallons of Shock and told us to run the pump 24/7 and do the DE cleaning when the pressure got up, and that in 3-4 days the water should be clear. As of yesterday it was still green and I've been bumping and flushing the DE filter. I decided to do water test strips and found that my FC is almost nonexistent, PH is down, alkalinity is down and CYA is nonexistent. Today from talking to people I've found out that this guy did it all backwards, he should have tested the water first and then added what was needed especially since the pool hasn't been used for a couple years at least.
So now I'm frustrated and I have no idea where to start. This is probably a 18,000 gallon pool, pump and filter are in good shape still. And my water is mega green
