I had my pool re-plastered late December, and waited until now to add salt. Went to Home Depot and got 16 bags for my 20,000 gallon pool. It was clearly labeled Pool Salt with 'highest purity'. But it was actually brown salt and created a oily film on my pool and totally clogged my cartridge filter. Here are a few pictures. I was not sure if this was normal, so took the pictures just in case. 4 hours later, and the pool shows brown staining on the 4 month old plaster. Entire pool is just icky brown and oily. You can see the picture of my skimmer that was clean before but full of oily scum after adding salt. Any thoughts on what to do? I stopped at 8 bags added given how bad it was getting. Help!
