there is tension in those wires as if it is a support to hold the walls of the pools to prevent collapse. you think it would be safe to modify those to make just one cable go across so we can put a volleyball net up?

anyone know if those 4 supports with the tension cables are needed? i see so many pools without those...

reporting back. i spent about an hour in the pool and my skin did NOT melt off. success.

that's good news. it's blazing hot in NYC today and this FC drop is taking it's sweet time. i need to take at least a 30 minute dip...

with a CYA level of 75 and an FC level of 14 (SWG off and waiting for FC to come down in sun light), when would you consider swimming safe if not submerging your head? i was thinking of taking a dip if it gets down to FC 10 by this evening...

thank you, jason.

need some help here... SWCG has been off for 24 hours (trying to get chlorine down). Yesterday's results vs. today (24 hours later): FC 22/16 CC 0/0 TC 22/16 pH 6.8/7.8 TA 130/100 CH 0/0 CYA 75/75 Temp 74/76 What I did yesterday was add dry acid to bring the TA down since it was 130. i...

I'll raise the cya tomorrow and then go for the ta lowering. Surprised I got so much chlorine out of the swg @ 50%

SWG installed tuesday morning running at 50% FC 19 CC 0 pH 7.8 TA 140 CYA 65 Temp 74 I changed from 50% to 20% on the SWG. It has been cloudy and rainy since monday. Usually the pool has direct sunlight all day long. My next step will be to lower TA...

Good point. Not sure why I didn't stick to the same thread...

The control unit shows 3000ppm, pool store shows 3100ppm. Should I add more? I have 50lbs left.
