I bought a house this past fall with an indoor pool that hasn't been used in a few years. It's 32' long and 16' wide and about 4' deep in the shallow end and 8' deep in the deep end and about 23000 gallons. It was built in 1980 I believe. We're having someone come look at it for repairs (there are some cracks and the skimmer has a hole in the side of it).

We'd like to install a salt chlorine generator as the pool currently doesn't have any sensitization system installed. I've read that indoor pools don't need very large salt chlorine generators since they don't get any sunlight. So what size system would I need? Are there any other concerns or special considerations for indoor pools?
