tranders Posted July 29, 2009 Report Share Posted July 29, 2009 Does black mold generally protrude from the pool wall in that you can 'feel' it with your hand or foot? Or does it grow flush on/in the wall? Quote Link to comment Share on other sites More sharing options...
AZPoolBuilder Posted July 30, 2009 Report Share Posted July 30, 2009 Generally it's Algae, not mold. It can grow under the plaster, in the plaster & on top of the plaster. It's not uncommon to actually feel it, but mostly it likes an area of LOW CIRCULATION, so you won't find it growing too far off the wall (if at all). Get some algaecide....or try scrubbing it with a 3" chlorine tab. You will find once it starts to grow inside the plaster, it's time for a new interior finish or pool remodel. Good luck Quote Link to comment Share on other sites More sharing options...
tranders Posted July 30, 2009 Author Report Share Posted July 30, 2009 Meant algae...and knew it! Need a new interior finish anyway, so just one more reason. Quote Link to comment Share on other sites More sharing options...
tranders Posted August 8, 2009 Author Report Share Posted August 8, 2009 I had three of these spots that were all very similar. One was on the side wall. And two were next to each other on the floor. All about 3" in diameter and fairly round. Rubbed the cholrine tablet on all three, and the spot on the wall was gone the next morning. The two floor spots were unaffected. Been rubbing regularly since to no avail. Left the tablet on for 24 hours which had no affect. I am going to try the vitamic C capsules and see if that helps the other two spots.
