Hey all. First post here but I have been getting great advice from reading this site all summer. I bought a house that has a 16-32 IG pool circa 1973. Original all aluminum, somewhere had a white Fiber tub sprayed in. Yes, I said sprayed. Well, this pool had not been opened for ten years before I bought. Absolute swamp. 3" trees growing from cracks in concrete deck. Removed over 2 tons of leaves from on top of old cover and from pool floor. Frog/toad breeding ground. Had to "relocate" over 200 frogs and toads to nearby river 'cause my 12 yr old has a soft heart for killing 'em.
Never owned a pool before but thanks to this site we got the pool to usable sanitary condition beginning of July. Still working on a few things but we're almost there. But I have one lingering problem that I can't seem to figure out...........
The sides of the pool have a beige/tan substance on them. Pool store tested and said it was copper, but I'm not too sure. This substance is the wierdest stuff. It is not slippery, or grainy. I got in and scubbed it with a hard bristled brush and....NUTHIN. Then one day I noticed my daughter's toe prints in this substance. So I reached down and wiped a finger across it and sure enough, white pool side. I then proceeded to use an old towel to just wipe and it comes right off as a milky/cloudy something. Almost like poring milk into water, only yellowish. Tested water for all algaes, nuthin. Used a towel to remove and then wrung towel into test bottle.
This stuff is really puzzling me. It doesn't come off when I scrub or vacuum but wipes off with your hand or a towel. Has anybody else ever seen something like this?
