THis is such a great site, I've learned so much about pool care on here. Thank you to all of the wonderful contributors!
I have an indoor pool with dull water. It is not cloudy because I can clearly see the main drains, but the water just looks "flat". It has been like this for about a week now. The backwash water also appears sudsy/soapy.
The filters, pump and flow are all in perfect operatio nand are backwashed as needed. There is no air in the system. The skimmers are not sucking air and the pump strainer lid is tightly sealed.
Levels are as follows:
CH: 180 (vinyl liner pool)
Water Temp: 81 degrees
Indoor swimming pool with 100 bathers/day.
Please help, I am open to suggestions because this is a mystery to me....
