brown spots on sides and bottom or pool

Postby poolgal » Thu 04 Sep, 2008 12:57

Help! Last year we bought a house with a 30 yr old Anthony plaster pool (20,000 gallons). We just opened it a few weeks ago for the first time. The sides looked a little discolored, but everything else looked fine. Now there are "brown" spots all over the bottom of the pool, and the discoloration on the sides seems to be growing. I am shocking it, now the chlorine levels are high, I bought a wire brush and plan to go home and try to brush it off, as the regular brush does nothing. Any ideas??

First step is to determine if the stains are organic (algae etc) or metallic. You can have a local pool store test for metals.

Try holding a vitamin C tablet on one of the stains. If it removes the stain then it's a metal stain, probably iron. It should lift the stain within a minute or so if it's going to work.

Thanks for the reply. I am fairly certain that it is metal - the iron reading was at 2.20. Any idea on how to remove the stains, short of buying a life-sized vitamin c tablet? :(

I would use the vitamin C tab to test how it removes the stain. Vitamin C is ascorbic acid and you can buy it for stain removal, but first check to see if it is going to work.
