Hey guys...
My water "looked" great last week, with virtually no winter maintenance.... except SWG. Last year, I was a little slow bringing the CYA and salt levels up, and ended up doing the algae shock treatment. So I got ahead of the game.
Last weekend I got the water perfect:
FC 4
PH 7.5
TA 75 (Goal is 70)
CH 270
CYA 55 (Goal is 75... but wanted to do it in steps and test again this weekend)
Salt 4000 (Seems hi, but that what the Zodiac LM-2 manual calls for
Borates 60 (Goal was 50, but overshot...ok)
Temp around 65
Note: Looks easy to remember with 75... for ph, TA and CYA!
The spring cleaning also involved some Jack's magic purple stuff seq, and a treatment of SeaKlear Natural Stain Remover to try and bring some nasty iron stains out of fiberglass (Didn't get a chance to order bulk ascorbic acid, refused to buy $44 Bioguard product, which I assume is vit C, and this was only $22... assume it's vit C also? no label)
The stain treatment process resulted in low ph, less than 7, and a significant addition of PH up product (sodium carbonate) after I ran out of Washing Soda. The SeaKlear called for 1lb/10,000... perhaps it was a mistake to double it?
Left town after the weekend, stain free and perfect balance. Return Friday to a cloudy, and milky pool with zero chlorine. SWG is weird with temp less than 65 and "add salt" light is on. Seems weird if it picked this particular time to fail, as it's been going strong for 5+ years (I run on lowest of five output settings).
So why the milky water? Infection or side effect of adding sodium carbonate? Started a shock regime:
Fri night sunset: zero for both FC and CC. Added bleach to bring to 17. Tested after 20 mins FC 13
Sat 830 am: FC/CC 8/1
So it looks like I've got something growing..... what?
