First, I should introduce myself. My name is Del and I'm a complete beginner, although I'm learning.
I am in the process of opening my pool and have shocked the water and backwashed the filter many times.
I own a vinyl above ground 13' x 26' x 48" 'Splash Superpool' that came with the house we purchased 3 years ago. I have never been able to maintain clear water and it's mostly because I was too cheap and too busy to buy the appropriate test kit/chemicals and to do what was necessary. I've now decided that I'm going to do this right if it kills me.
Anyhow, last year, the Hayward Pump/Sand Filter quit on us, so I am using an Intex Pump/Sand Filter that I had to buy converters for to rig up. I had the Intex rig when I owned an Easy-Set pool. It always did the job on that thing.
In the past, I mostly relied on advice from the local pool store when setting up/maintaining. This worked fine when my pool was only 4,000 gallons, but now I own a pool that's just over 10,000 gallons.
I recently purchased a Taylor K-2006 Complete Test kit and have tested my own water.
These are my initial readings:
CYA=20 (The pool store's last test said 70, I don't understand this discrepancy)
My pool water is cloudy, but I can 'see' the outlines of a yellow-ish silt on the bottom. This silt never goes away completely, no matter how much I filter/vacuum
I am wondering if my filtration system is large enough. The one I replaced was much larger, but that system was for pools up to 25,000 gallons. This system I have now is recommended for pools up to 12,000, and should work, but I fear it is insuffcient. I know I should also probably shock again to do something about that Combined Chlorine level.
Any help is appreciated. Thanks.
