About 4 years ago I bought a 1940's home in foreclosure with a pool that had been allowed to turn into a disaster. I have managed to get the pool cleaned up and functioning for the last few summers, but I'm continually having problems with algae coming back with ANY weakness in chemical levels (and sometimes even when things seem perfect to me).
I will say this pool has stains in it from when a previous owner let it go and then tried to clean it up - so even when the water is perfect it doesn't look great. I'm thinking it must be a 30-40 year old pool.
I noticed this last summer that the pool has nasty breaks/flaking/digs in the gunite where algae is growing and I just can't scrub it out when I'm cleaning - so I don't think I'm ever getting rid of all of it.
At this point I'm very frustrated with trying to keep this thing clean the fact that it never seems to get totally clean and reasonable to manage like I know it should be.
Are there any options to clean up the gunite and get this thing back in shape without re-surfacing the entire thing? I don't care if it looks perfect, but dealing with this algae problem has got to stop.
Thanks for any advice.
