I have visited this forum quite often...wonderful place to find some wonderful info! So, I finally registered in order to share my troubles with you guys and hopefully get some help and advice. And, maybe, if I can overcome this mess of a pool I have, I can later help others. I'll list all the info below, but first off, I dunno even know if I can ask a specific question...we'll start with the problem-S.

Okay, we opened the pool May 29. It was about half full, clear, but full of leaves and debris probably from last fall before we got it covered. We added fill water from a stream that is in very good condition (everytime we've filled, it's been near perfectly balanced). This, of course stirred up the mess on bottom, so we blindly dug the leaves out. The next morning, the water was dark nasty green. First things first, I added chlorine. We'd clean the debris out, brush the walls and floor and add chlorine while running the filter 24/7. The water started looking better within a few days. Took a sample in to a local hardware store that does pool testing and discovered low hardness, low alkalinity, great pH, through the roof chlorine (lol...which kinda freaked the hardware store ppl out) and a high combined chlorine along with a copper reading of 0.29. I thought it best to keep up the chlorine until I didn't lose any ground overnight, before adjusting everything else.
So, after about a week, the water looked better (turned a lighter green, kinda light olive color, but still cloudy), and the chlorine was holding wonderfully. I waited a few days to let the chlorine come down in the hopes that the cloudiness would go away. Just in case something was alive that I was missing, I added an algaecide for insurancce...unfortunately, it was a copper algaecide, but around the time I added it, I noticed you could faintly see the bottom of the pool. I added a metal out as per others advice and my own thinking maybe the high levels of copper was keeping the water green...it was no help, no change. My chlorine was still normal, so I decide to adjust all the levels (used baking soda and hardness increaser). This made the water clarity a little better, but still only faintly see the bottom and still light green.
Had water tested again and everything was near balanced except the copper...it went up to 0.79 and I now was reading an iron level of 0.11! Never had iron before...? I come home and decide to vac to waste and pump some new water in to try and help that metal level. I do this and test again...copper dropped to 0.51 and iron was 0.0. Was still not happy with that copper, thinking it was making my water green, so I added a dose of metal out plus.
That was two days ago (test today showed 0.38 copper and 0.0 iron). Pool is still light green...it's looking bluer around the edges, but no major change...I can still see the bottom very faintly all the way around the pool, BUT, this evening, I found some pink stuff around the fittings on the inside of the clear pipe between my filter and pump...guessing I have that pink slime stuff...? Could it be affecting the light green water in the pool? I have no idea what I'm dealing with here or how to fix it. Draining (to a safe level) is what I'm thinking, but I wanna make sure I do everything right and get everything cleaned up properly. Any help, advice, experience, or instructions would be greatly appreciated!

I apologize for making such a long post, but I wanted to tell everything I've done up to this point. Thanks again to anyone who can help!
