Well, new salt pool owner here. Have a pool guy. Have my own Taylor K-2006 test kit, trying to get comfortable testing while the pool guy is still around. Have a pool supply store that is eager to sell me everything, in fact (after doing some reading on this fine site) realized that they sold me $120 worth of chemicals that I did not really need. Thank you Leslie's, most of it is coming back to you.... except the acid! Quick rant over....
My pool is less than a year old. I have noticed several small "stains" 1/4" or less on the floor of my Pebble-Fina that just will not leave. On a quest to find out why they are there. Barely any landscaping around the pool. Did the vitamin C test to be sure not metals based stains. I've done desperate mechanical things to eliminate these stains to no avail. Things like stainless steel brushes and pumice stones. On my new pool made me want to cry with each brush stroke. Pool guy says he thinks it's organic matter falling to the floor refusing to leave. Pool store says it's black mold (in a pool that has never been used by me.... yet) because my phosphates are high, and that it comes from the dirt beneath my pool, leaching into that porous concrete. Oh lordy..... a little frustrated that I am paying for a pool service that "may be" letting my pool go to Hades. Who to believe? Now that I know phosphates are NOT a problem when my FC is not low (which it never has been) I have no idea what these stains are. They can't possibly be black algae.... can they? FC is NEVER below 5. Screen shot of my testing, albeit brief since I just started doing this. I really should have started testing when I hired the pool guy on. But it was November. If it is algae, is it possible it was imported to pool when pool guy does maintenance?
