I'm so glad I stumbled across this forum! We just opened our 15x30 pool for the first time without draining and completely starting over (we have had the pool for three years). Truthfully, we have had no problems with keeping the pool crystal clear.
However, this year, we didn't drain and start over with fresh water. We just decided to shock it. We did fill the pool about 1/3 with new water because of the winterization. We did, also, have some leakage from our pool cover this winter which made our pool water green.
Now, tell me if I am on track. Doing a pool opening is somewhat new to me starting with the green water.
We have shocked and shocked and shocked and algeacided the pool. Since opening 2 days ago, we have used 5 bag of super shock, 2 gallongs of liquid bleach, five large crushed up and diluted chlorine tabs, another 2 gallons of liquid POOL shock, more algeacide and PH increaser.
On the test strips, my readings are just now:
TH 250 (ok)
TC 10 (high)
FC 10 (high)
ph 6.8 (will add more)
I will get the PA up and add more stabilizer (should I get Borax?).
I has been 2 days, should my water have cleared up somewhat by now? It has, truthfully, but is still cloudy and somewhat green/blue.
Do I need to be doing anything else? We are also running an auto pool cleaner at the moment (just turned it on an hour ago)
How would I tell if my sand filter is okay? This is the third season we have had the pool. Should it be okay after 3 seasons? My pressure stays at about 10 or 11. Really doesn't go over that. ***Edit *** I should mention that not last season but at the end of the season before 2007, the pump thru my stupidity lost it's prime for about 10 minutes or so. The pump was making a slight "squealing noise" however, upon opening and running it last year, all was fine. Now, we are hearing it again. Could we have a pump problem????
Should I be backwashing more or ONLY if the pressure goes up? Thanks for all your help!
