cloudy water

Unfortunately it sounds like you still have algae. You probably didn't get it all before, it comes back if you don't kill it all at the same time. The only way to make sure that you did is to take your chlorine up to (with a cya of 80) at least 20 and keep it there until you don't lose more than 1ppm overnight. You will have to get rid of all the algae before you tackle the stains, or you will just be wasting your money and pool time. You can swim with stains, but you can't swim with algae! If it were my pool, I would take it up to shock, keep it there until it holds chlorine for 24 hours, especially that it does not lose more than 1ppm overnight. Once you are sure that you have no algae, and the water is clear - not cloudy, then you can start with stain treatment, if you have any. When you are ready, take the ph down to 7.0 - 7.2. Add enough sequestering agent for your pool according to the bottle. Sometimes this will be enough to lift off the newer stains. If you still have stains, make sure you add some algaecide, let the chlorine drop low and use ascorbic acid. Let it circulate for 1/2 hour on recirculate setting on you filter, when you don't see anymore stains you can put the filter back on filter and keep it on 24/7. After about 12 hours you can start to bring your ph up. Once it is back in range (7.2) start to add bleach a little at a time watching for stains. You want to get it up to 5 with a cya of 80. If you see any stains start to come back add some more sequestering agent. Make sure your chlorine never goes down to 0. Sequestering agent uses up chlorine, and also brings your ph down. You will have to test a lot, and keep up with it. You should then be stain free! Let me know if you have any other questions,

I was typing while you posted! Since your cya is lower you can keep your chlorine at about 3 - 5ppms. All else is the same!

thank you
I will add bleach tonight after testing again to be sure it is at a shock level

Also, since your CYA is 45 instead of 80, then your shock level is 15ppm instead of 20.

thanks I was wondering about that

Just came home to a clear pool, YAY! Thanks soooo much! ...and I don't see any metal stains, I will try my best to keep it this way!
fc 12 cc0 water clear but I can brush particles off bottom it may be algae, not sure so I will add a gallon I think in the morning I'm all out now, lol I also back washed again, more green came out

Yeah! Just make sure you keep it at shock levels - especially until your backwash is not green. Glad the stains are gone!
