I need help. We have a 90 year old in ground concrete swimming pool which measures 50 x 20 and depth is 4 1/2 feet which drops to 10 feet. There is a lot of water. The pool is fed by a spring. Maintenance has been drain pool in the spring and clean the sides with a power washer. We then fill the pool and I would every few days depending on the use toss in about 4 cups of granulated chlorine and would have clear water.
This year for some reason the water is cloudy with algae and I have tested the pool for the first time ever in 40 years of living at the farm. Showing all items ph, chlorine, stabilizers high.
I don’t know if the product (chlorine I am using is different. I tried a product to remove algae and waited 24 hours nothing. I tried a flocculant (SP) and nothing. I know this pool has a lot of water as most of the pool is close to 10 feet deep. It doesn’t really have a shallow because as I understand it, it was built when the children in the family were teenagers and good swimmers.
There is no pump. There is a pipe intake that can be diverted to the pond. My husband has refused to install a filtering system.
The only information I find online are very large spring fed pools in Austin, Texas and a few other locations in the US. Lots about organic pool which this is not.
Any information you can give would help. I realize this is unusual but John had responded to someone about pool and seemed very knowledgeable.
I would like to have this issue resolved because local township and city pools are closed and our grandchildren, children and their friends know and use the pool.
Blessings and prayers for everyone’s safety at this time.
