We have had this Intex above gound pool (22') for 2 years. This is the first year that we have tried to start with last year's water and we are at a loss. We have been fighting with our Saltwater pool for 3 weeks now and have spent quite a bit of money. My pool cover did not stay on over the winter and therefore when we started we had a lot of leaves in our black pool.
We started by removing leaves and attempting to SLAM my pool with 8.25% bleach first. After much of that the pool went from black to a dark mud brown.
We tried floc twice which seemed to make a small difference making it less dark.
Per the recommendation of the pool company that had been testing my chemicals I bought and used YellowOut following the directions on the bottle which seemed to make the most difference to date.
We tried YellowOut a second time which made no difference.
Included should be two pictures of what the pool looks like now. It is still the lighter brown color and seems to be turning a little bit green again if you look straight down in the pool.
Any ideas that can be thrown out there would be appreciated.
I have a printout from the pool company's test from Wednesday. I have been back a few times since then but don't have the printout.
Free Available Chlorine - 1.5 (according to test strips it is currently at 10ppm due to dichlor I have put in)
Total Available Chlorine - 1.5
Salt - 700 (have salt but am waiting to put this in)
CH - 50 (I have the fix for this but am waiting to put it in as well)
CYS - 80
TA - 80
PH 7.2 (my test strip shows about 7.4 today)
Copper - 0
Iron - 0
Phosphates - 100ppb
I have not started the SWG yet as I don't believe it would do much good getting rid of the algae. Mrs. Crump is concerned that the brown is not caused by algae but something else but we are not sure what it would be since the copper and iron are 0. Is 100ppb on the phosphates high enough to worry about. It just seems like we keep guessing at this and can't get to clear water.
Also, one last thing to note. I have noticed that there is a small amount of sand where our filter's backwash drain is. Is that normal or is something wrong there? We have replaced the sand and checked the pipe that runs down the center of the filter and there were no cracks in that. Is there anything else I should check?
Thanks in advance!
