I read Sir Mixalot's post about stains in the pool. I am having similar issues, but it is definitely not fertilizer, since I don't use it. I do, however, have a very large red oak overhanging my deep end. Its dropping something into the water that is staining the pool. The droppings (operative word, I think) are not coming from the tree itself. They are a 1/4 inch long, maybe an 1/8 inch wide, shaped like a barrel, and looking like a mini ear of green corn. Or a mini hand-grenade. They are soft, and have a slit down one side. They stain the pool and the stains won't come out.

I swear, it looks like doody of some kind. But, as doody goes, these would be a feat of doody engineering.

Any ideas?

It looks like a mullberry that has gone through a bird fast

Well howdy doody - shoulda thought of that. Good call. Strange that it stains the pool so badly.

Thanks! Now where'd I put that b-b gun?

Take a long piece of 1.5" pvc pipe and place one end down in pool over the stain, pour through other end a couple cups of muriatic acid down pipe (its heavier than water) and it will sink to stain and generally remove. DO NOT overdue it or it will pit your finish.

Once complete balance ph using backing soda or soda ash.

Hope this helps

Or, put some vitamin C tablets in a white sock, tie it closed and throw in the pool on top of the stains.
