Light green water

[Huskerdee]

I have a doctor appointment in the city tomorrow. I will stop and get cal hypo and do the testing of hydrant water when I get back.

about 1/3 lb in the skimmer at a time. You must be 100% sure no other chemicals are in the skimmer, or anywhere between the skimmer and the filter. The pump must be on, and remain on for at least 30 minutes after.

Sorry I haven't replied sooner but am 45 and 7 months pregnant. Have not been feeling well. Anyway, my pool is a slight color away from being clear. I tested my hydrant water which is where we fill from. The PH is 7.2, alkalinity is 375, and calcium is 310. I just received a test bottle from our health department to test our iron, manganese, and copper. I will have those in a couple of weeks. However, I expect it to come back high in iron and possibly manganese too. I know the copper isn't high because I've tested that and besides our house is old enough they used cost pipes not copper back then. I have a question. I'm pretty sure I killed any green algae there may have been. However, every morning when I go out and look there is a dark green or brown sticky substance along all the seems. Would that be black or mustard algae? How do I get rid of it because heavy shock, brushing, and vacuuming does nothing, it just comes back.

I'm going to let Ben address the first of your questions. But, regarding the seams of the liner ------------ my guess is that it is pollen and dirt that have settled in those lines. My liner pools have always done the very same thing. I can vacuum the pool and have it supposedly pristine. But, the vacuuming process has fine particles (dust, pollen) stirred up into the water. Then when the pump is shut off and the water gets still, that fine stuff settles back to the floor of the pool and settles in those lines. Happens over and over and has been true of every liner I have had. I cleaned my pool yesterday, but I'm pretty sure if I went out to look, I'd see those lines of debris. Not a lot you can do about that, unfortunately.

In my experience, it would be extraordinary for water like that to contain iron . . . and it's very unlikely that that water would cause iron to rust much, either.

I'm not sure what's going on -- I'll very interested to see the test results on the samples you sent in. Meanwhile, just chlorinate and filter. Seriously, a clean white 5 gallon bucket, filled with 4 gallons of tap water will tell you a lot. Add a teaspoon of bleach each day, and stir. See what settles out.

Sorry you're having challenges with your pregnancy -- hopefully, it won't get too hot before you deliver!

Thank you. I had two spinal fusions and a discectomy so I have a hard time carrying the extra weight. I'll get through it but can tell when I've over done it, lol. Anyway I will do the bucket thing as soon as I can. I'll keep you updated. Thanks for your help.
