I got a 30 foot above ground pool installed around August of last year (no salt, yet!) and we got a bit of usage before having to close it for the winter. Apparently my winterizing efforts were lacking, because I pulled the cover back and found a green swamp about a month or 6 weeks ago. I have read on here how to recover from an algae bloom so I have been trying to do that. I have a heavy duty scoop net that I used to get most of the gunk up with. I have been adding tons of bleach with little regard for calculations. I have also added algaecide and shock. Finally the other day, I was able to see the bottom but the water is still a cloudy green.
I caved in and bought the TF test kit and finally took the time to test the water tonight. I know this might sound surprising, but I ended up adding 75 drops of the r0781 to my blood red water to get it back clear. Then after the 5 drops of r0003, it only took 5 drops to clear it up again. I have to admit I have no idea what this means but I know there are some gurus here that can decipher for me. The alkalinity test was about 17 drops from blue to yellow-ish, CYA was 80 or so I think and lastly the PH was about 7.0.
So tonight I ran my little aquabot pool rover junior for a while, backwashed the filter, added about 3 or 4 lbs of baking soda, and left it. I'm going to attach a few pictures below, of the water and some of the stuff I've added to the water, in addition to about 30 gallons of bleach. I was hoping I could read enough posts on this site and figure this stuff out, but apparently I can't. I just built a lovely pool deck this past weekend, and here in south west Tennessee, it won't be long until it's warm enough to swim. I gotta figure out how to get this pool clean again. I would greatly appreciate any help you guys can provide.
