Pool Closing Headache

[CarlD]

Does the pool wall where the green is feel slimy? If not it may not be algae but possibly metal. Have you checked your copper and iron content?
Of course, if it feels slimy you are fighting algae.

Forgot to mention nothing is slimmy & the bottom is not slick at all. On Saturday morning i had 15.5 from 16 the nite before. Vacumed very carefully so not to put anything back into the water & gave it it's winter dose of polly so i had time to get the chloride back up. On Sunday had a few deposits in the cracks, vacumed them & stayed on top of the chlorine. This morning virtually had no deposits, chlorine was back up to par, did a quick vacume, dropped the water level, pluged & capped & put the coner on it. I have never had any problems with metals, i guess i'll find ou next spring. Thanks again for your help, i have never had anything like this happen & your system works great.
