I have had this problem with my cement ingroud pool. The pool person I work with says that it is caused from iron in the water. She recommended the use of "Stain-X" which seemed to help. She said you had to either raise or lower the PH before using it in order for it to be effective. I forget which, but you can probably ask you local pool store about it. I fill my pool with well water and believe it or not, she always has me put a folded sock or old t-shirt around the end of the hose and fasten it with elastics before adding water to the pool. It may sound silly, but when you look at the sock after a day or two of running the water, it's all discolored. Good luck.

What causes permanent brown stains to a fibreglass pool?
Normally caused by calcium build up or caclcification. Prevetion and cures can be found on my blog.See the link on this message Permanent brown stains are usually caused by "iron". Rebar attached to the pool exterior and encapsulated in bottom of a concrete deck is the usual suspect. Another cause, which can be reversed, is an older heater. If a heater is involved, have the headers and impellers checked for iron. If they're iron, have them changed-out, then try a sequestering agent following the directions. Permanent stains in fiberglass pools are caused by either iron (brown), chlorophyl (green), or air holes caused by failing gel coat (black).
