Hi, everyone!
This will be my first season on BBB - started late last season and liked what I was seeing. I'm looking forward to being a full BBB guy this season, but need some guidance.
Here are my specs:
16'x36' rectangular, 3.5' shallow, 6.5' deep = 21,600 gallons (give or take a few hundred gal. for steps and 2 benches)
In-ground, Plaster
2" PVC
Challenger PAC-FAB 1.5 HP pump (around 50-60 gpm, I think??)
Intermatic digital pump timer
Heyward S244T sand filter (3.1sf, 20gpm/sf max flow) - changed out sand at end of last season.
Aquabot automatic cleaner (electric powered)
TFP test kit
I'm in NC, so Av. outside temps are around high of 70-80 / low of 50-60 right now.
Pool was opened 2 weeks ago after being covered for the winter. Water was dark green. First week did not have great filtration, because my pump was not completely catching prime (pump basket needed new gasket). First week, was filtering 7-8 hrs per day, backwash every few days revealed lots of yellow & green (pollen & algae/slime?)
Starting values (2 weeks ago):
FC: 0
CC: 0
TC: 0
pH: 8.2
T/A: 110
CH: 320
CYA: ~90
Water Temp: 65
Vacuumed out leaves and muck 5 days ago (dumping vacuum water to waste), emptied about 10" of water, which I replaced from tap. Also ran Aquabot for several 4-5 hour sessions, he is now just picking up silt and a little green slime.
Added 20 x 96oz. jugs of plain Walmart bleach (6.0%) Sunday evening to shock the you-know-what out of it. Tests for the next few days showed off-the-chart FC, ran pump (now operating properly) 24/7 since then. Water has turned to somewhat cloudy with light green tint. Can now see bottom in shallow end, but can only see 4-5 ft down in deep end (deep end is still dark green, but a little lighter than it was when pool opened).
Today's test results:
FC: 4
CC: 0.5
TC: 4.5
pH: 7.6~7.7
T/A: 80
CH: 300
CYA: ~90
Water Temp: 65
I know that I went a little crazy with the bleach (was under pressure from significant other!)
What are my next steps? I'm filtering 24/7 and have not sen much more progress. Backwashed today and saw some yellow, but not much.
Thanks!
