Pool Stains - unsure what kind and best way to proceed

[tmcdonald]

Thanks for your help and info. I've been sidetracked with work, life, etc. and am just now trying to get my attention back on the pool.

1) I have been using a lot of copper algaecide over the last few years to combat serious algae problems..this is what the pool store told me to do. However, these stains were present BEFORE I started using these chemicals - although they may have gotten worse I'm not sure.

2) If I follow the steps you mentioned and purchase all of those products, can I get the pool balanced and keep any eliminate any existing algae without the use of copper algaecide? I don't have a good test kit and have never really gotten the pool balanced well, nor do I know the process without using algaecide. I'll look into what you suggested.

3) My pool is ~ 25,000 gallons I believe.

At this point I'm thinking that trying to remove the stains will have to wait until next spring. I just want to get the water balanced so that I can enjoy the pool and not have to dump a ton of money into algaecide and other products. I already need to replace my filter sand .
