Been maintaining pool for 3 years with chlorine and TFP methods. Came back from vacation to this. What in the world is it? I can't remove with a pool scrubber.
Pool had chlorine added in liquid and tablet form while gone. Pool is clear with exception to this.
I've not ever used any ironizer or anything special in the pool. Liquid chlorine and acid balancer and that's it. Last pool store check of all levels (including TDS and CYA were in check).
Pic from night cause I just discovered. It's brown.
