Some days ago I was talking about one pool (the one labeled on my signature as "GM") with some sort of algae problem, but principally a problem on the walls where the algae seems to be very difficult to remove.
One suggestion we got was to drain all the water from the pool, and then use some acid? to brush and remove the algae from the walls.
Do you think this should be done independetly of testing the water and getting the chem numbers, etc.?
Or just by testing the water, and shocking the pool you can get rid of the problem with the walls?
I am still waiting for the TF-100. Should arrive soon, but until then I am wondering if this "cleaning" with acid (what kind of acid??) could work to get rid of the algae?
I am attaching some pictures. Will take better pictures today and will post them too. These were taken with my cell phone.
Thanks for any suggestions.
