    Rust dendrites on plaster side-wall...

    Sorry, don't have a picture.

    But I have a pool with Rust dendrites (spots, with raised rust on them) growing through the plaster on the side-wall, about 1' apart. The pool is a dark plaster pool.

    Any tips or concerns (heck, I'm concerned).

    Thanks.

    - Jeff

    p.s. I might get a picture next week...

    I've got a rust spot coming thru the plaster. A photo is in this thread. Title is a little missleading.

    I'm waiting for the PB to come and and look - which could take several more weeks. He claims its black algae, but has not even looked yet. You can clearly see rust blooms in my photo.
