What causes a rust spot on the bottom of a pool?
Rebar spots are rust stains. They are formed when water from the pool seeps through tiny fissures or cracks in pool’s surface, and it reaches the metal framework in the lower layer of gunnite (Bottom layer of Concrete). When it does, the steel rebar rusts, and this rust seeps back up through the structure to the surface forming a rust stain.
Do you need to fix a rusted pool skimmer?

Can a pool have a bleed through rebar stain?
A rebar stain in a swimming pool or spa is a serious issue. Rusting rebar will continue to corrode within the pool structure until all corrosion is removed. Although the bleed-through stain may be small in size, the corrosion beneath the plaster (in the gunite) is always larger in scale (see photos below for examples).
