Pool problems on startup

[michael3]

Found that about 2 cups seems to be a good number for me. The pressure rises about 2 psi and it takes about 3-4 hours to reach high enough to backwash. Stma do you still have a green tint or just cloudy? I still cant shake the green

Mike, I kinda lost my green tint a little, but I'll tackle that when this thing de-fogs ( if it ever does).. Back in your first or second post, you mentioned something about adding shock that contained a percentage of copper.... I too, in the past would have this nagging green that would never disappear....Very Very slight hint, but it was green nonetheless.. I found it to be metals in the water (I have well water here)... now I know how to deal with that....
all that said::::
real simple: take 2 or 3 vitamin C tablets from the medicine drawer.... place the pill inside an 8- folded paper towel, the bottom of an old sock, an old rag etc... take a hammer and crush the pills up abit...now take that towel, rag or sock, and rub the side wall of the pool with it and see if you see a stain coming off.... If you do have metals in the water, it will be quite noticeable once you rub the pool wall as the stain will disappear before your eyes ... its actually pretty cool to see... If the metals are present in the water, dont sweat that until you get the cloud "thing" under control... Remember the color wheel : >>>> Blue wall+yellow stain=green appearance

Cool, now to get some vitamin c, would not surprise me at all if that's what I have. My liner is almost 10 yrs old and not in the best of shape. If I can get the clouds gone from my water, I may be able to live with green looking walls and bottom lol

[stma]

it wont take alot of "C" to find out... just ball it into a paper towel, and rub that "ball" on the liner... You'll know in an instant if its metals....

[michael3]

Well I`m happy to report ....... I am still clueless lol. Got some vitamin c, rubbed the pill up against the liner and nothing. I guess you can do that right? So, it doesnt appear to be metal, or will the vitamin c work on copper stain? Still dont think its algae at this point, Chlorine has been high enough, long enough to kill anything in that water lol.

Vitamin C works on copper.

Unfortunately, some organic stains can be removed only very slowly with chlorine . . . and I have seen some that were never removed. I don't know of any other way to remove them.

With the age of my liner, if we can get the water clear, can probably see about 2' down now. I am ok with green colored wall and bottom lol. With my chlorine holding overnight, and getting no cc on that test, do you think I can go ahead and bring my chlorine level down to the cya guess chart? And with the pool being cloudy, do you think it would be safe to swim in, we're nearing the end of June and have not been in it once I have a 5 yr old that just doesn't understand why she can't swim
