My family and I just moved into a house that had a pool. Thus, we are brand new pool owners.
The previous owners were elderly and their son was taking care of it up to last year. The pool was green when we moved in back in August. The filter cartridge hadn't been changed since last year, but I started backwashing it to get it clean enough to run again. Using some tips from this awesome site, I managed to get it clear again and got some swimming in. Unfortunately right before closing it down, the pool became green again. (Due to external factors, I did neglect it a bit. I'm guessing from the falling leaves and rain, it pushed the algae growth up a notch.)
The pool liner was torn in the corners and was "repaired" by the last owner using duct tape. The pool is about 10 years old and is still under warranty. We were planning on getting new liner and pool heater (previous owners bought it last year and kindly left it for us) installed first thing next spring. Looking ahead, I was thinking of saving the money and time and closing it down green, seeing as it's going to be replaced anyway.
This comes to my big question:
Can I close the pool down while it's still green? Will it damage the filter unit at all?(nevermind the cartridge, because that needs to be replaced.)
Thanks. I hate to see it the way it is, but any money I can save for getting the new bits installed next year would be great.
