Hi all! Newbie here....new and stupid.

Bought an Intex 15' x 42" Easy Up for the kids, spent a week clearing, leveling & setting the thing up. Started filling it two days ago (we have well water so it took the better part of two days to fill.) We were very confused at the store so bought a "starter kit" and added 4 oz of "shock" for approx. 3,800 gal. ran the pump several hours as our well water is naturally "tea color" (we were told by a local water "expert" who tested it years ago, that we have tannins, decomposed tree bark in our water.) We drink reverse osmosis water in the house, but the outside water is not filtered. At first after filling the pool the water was a clear tea color, we could still see the pattern on the liner bottom. After adding the super shock product (Calcium Hypochlorite) and running the filter most of the day the water turned dark brown and cloudy..the bottom disappeared so we added another 4oz of shock at night. The next morning, I started the filter early and discovered the pool had been taken over by gross amounts of backswimmer bugs so we added 4 oz of algecide. Skimmed the bodies off and finally figured how to hook up the skimmer that came with the pool and kids were able to play for a couple hours. Again, we treated with 4 oz of shock overnight, thinking maybe we hadn't "shocked" it enough. Woke this morning to more bugs and even dirtier looking water. I tested with strips, CL wasn't even registering up to this point so tested with another tester & drops, CL levels very low (light yellow) ..so today I dumped in an entire 1 lb packet of shock and 1/2 the bottle of Algecide, forget measuring, just kill something!!! Next we were going to add a metal defuser to see if that helps with the brown water. It could be tannins, it could be iron too. oh, I should mention that I've been rinsing out the filter cartridge about every 6 hours..it's BLACK & sticky gooey like tar. We bought a chlorine tablet floating dispenser hoping that would help bring up the chlorine level, but took it out when we added that last lb of shock. Obviously we don't know what we're doing, we're throwing everything in it trying to bring it around. I wished I'd known about PS first, we would have started with bleach. As it is, we're AFRAID to get in it, it looks like swamp water that alligators would swim in.....help us please, kids want to swim.
