Hey everyone, since joining this site under a month ago, I took ownership of an older house with a 30 year old pool. The previous owner converted it from a pool with a deep end to a sports pool. He also did some mosaics of fish and other sea life on the walls and floor of the pool. It also looks like he "painted" the pool walls, because you can see what looks like white, clean surfaces applied with a paint roller if you can imagine that. I will try to post pictures.
At any rate, since getting the pool, I was able to eliminate mustard algae, get RO filtration on it to remove elevated CH and CYA (not allowed to drain / fill pool), and get crystal clear sparkly water via the TFPC method. You guys are wonderful.
So... I went swimming in it with my kids for the 2nd time ever and noticed something NEW. Those white "painted" surfaces are slimy as can be! When you rub your finger on the slime, it feels like paint, and white stuff gets all over your fingers. I am convinced it is not anything organic as my FC has been adequately maintained for 2 weeks now and CC has been 0.0. Is this some sort of pool "paint" that I'm dreading the previous owner used? My neighbor jokingly said that the owner painted his pool. Maybe he wasn't kidding!
My plan is to brush all the walls and remove the white slime. I recall early on when I got the pool that there was a TON of white stuff on the floor of the pool which I constantly brushed. The filter had to be cleaned every couple of days in fact and that white stuff rinsed away when I hosed the cartridges down. Is this a good plan? just keep brushing the remaining slime off the walls and filter it out?
I think as the white paint comes off, you can see dark splotches underneath. Perhaps after I remove all the paint, you guys can advise me on my next steps. Remember, I CANNOT drain and fill my pool as I would be fined due to the Southern Cali drought we are in.
Thanks for everything guys!
