Calling all ye' pool gods, I'm stumped after searching the interwebs.
I've got what appear to me as calcium deposits all over the bottom of my pool. Most of the plaster is pretty clean, but I have these things. (Sorry, the picture isn't good, I'll try and toss the go pro in this weekend and get better ones.) I have small calcium deposits on the walls also, sort of look like stalagtites (stalgamites? I don't remember which ones grow up and which down )
If I scrape them with a putty knife, they do break off, and leave the gray stain. At least I can get the lumps off.
I'm wondering should I do a drain, scrape and acid wash? My other option is borrowing some diving tanks and scraping them down by hand. I'm just not sure what they are.
Now,I'm in Phoenix - our water is about as hard as a pumice stone coming out of the faucet (hence assuming they are calcium?) - The water is crystal clear, with FC, Cholorine and acid levels normal (aside from the leaves, I had the robot cleaning up after the last storm.)
I'm open to any and all opinions. I just have no clue....
