green water or green liner?

[denanbob]

I did have it tested at the pool store and those are the numbers they gave me. They don't test for FC/CC's (eyeroll). I use a drop based test kit from WalMart, not strips. I have not added anything containing copper except Algaecide last year before we closed. The sides do feel a tad slippery/maybe considered slimy. I added 3 more gallons of bleach this morning. Here is a pic, hope it works:

As you can see, the first 6 inches or so are blue but from that point down, everything is green (which makes me think the liner turned green). I just can't tell if the liner is stained green or if the water is actually green (although like I said above, if I fill a water bottle with the water from the pool, it looks clear, not green).

Usually, I'd say just go with more chlorine, but I dunno. If the liner feels slippery, you are probably fighting algae. But if it's not and "squeaks" against your fingers, that's not it.. I'd have the pool store test for copper and iron, if you don't have your own metals testing kit.

Update: You say it feels slimy. Shock the heck out of the pool and brush it every day. I think you still have algae.

the green tint is probably the water- small amounts don't show enough tint, but at 4 ft depth you have enough to give color...
I agree to shock it- definitely won't hurt it, reasonably priced, and if it fixes the color won't have to worry about metals testing!

Thank you everyone! I put a TON of bleach in it (figured it couldn't hurt), and it is now a beautiful shade of teal so it is getting bluer! So I definitely think it was the water and not the liner. Thank goodness. We had SO much rain last night, I just have to hope it does not overflow and cause more problems...ha. We both had to work this morning so did not have time to drain it, but it is almost to the top...ugh. So I shut pump off, and will drain some tonight, add more bleach, and hopefully we will be back in business on our way to a clear pool just in time for the beautiful sunny/hot weather coming up for this weekend! Thanks again!
