I've owned this house with this pool for about 10 years now. Sadly, I've really grown to hate the pool: it's like having a toddler; you can't leave it alone very long or it will get into trouble. That being said, we've had our share of issues: underground pipe leaks, pump dying, heater dead, spa tiles falling off...
Anyway, for the past two seasons, I've been having a lot of trouble with keeping my pressure down. Even after I completely pull the DE filter apart and clean the grids, I can only get the filter to run for 8 hours 2 days in a row before the pressure jumps up to 30+ psi. For awhile I thought it was a mechanical problem, but now after finding this forum, I'm wondering if it's a chemical problem.
I bought the big kit and here are the latest numbers:
The water is cloudy and when I pull apart the filter to clean it, there's definitely a green to it. I also have trouble with calcium build up, particularly at the waterfall from the spa into the pool.
Any initial thoughts based on this?
