I am out of ideas now.
I did my second ascorbic acid treatment according to the description here on the forum, on last tuesday 12 April. I also used a culator 1.0 pouch in the pump strainer and one in the skimmer basket. I took several days to bring the chlorine up very slowly. I was afraid I brought it up too fast last time (about 4 weeks ago) and maybe that is what brought the stain back. I have some green looking algae growing in the corners and seems of my liner. I can tell that the liner is changing color again looking like the freaking stain is coming back. I am completely frustrated. Here are my readings as best i can tell with leslie's pool strip:
ALK about 100
I also confirmed FC and pH with an aqua chem kit and got the same results.
1. Am I wasting my money on the culator pouches?
2. It has only been a week since i did the AA. Should I go ahead and shock anyway to kill the algae? Is there another non-metallic way to kill algae?
3. I used Algaecide last winter without knowing it has copper sulfates. Am I correct to assume that is the source of the metal stain? I have not had my fill water tested, but every time the pool store tests my pool water they say there is NO COPPER in my water. (not that i trust them)
4. I also have this mucus looking stuff on top of my pool water. kind of reminds me of frog eggs. It is a clear film with a small orange or brownish dot in the center of it. Several individual spots of this floating in the pool. I will try to post a pic of it if I can get it to take. Anyone have any idea what it might be? I have lots of trees around, but have not seen this in the last 10 months that I have owned this house.
Please help. I am at a loss and getting frustrated. I am not rich, so "the pool guy" is not an option. I would rather learn to take care of it properly myself anyway.
