Hey Soxlover...welcome. I'm an industry person too.
TFP is not really a pool owners vs pool industry people site, sorry if it looks that way.
It's a pool owners vs untrained pool store people that give bad info and don't care for the customer site, were the pool owners WANT to learn about their pools so they are more knowledgable and aren't paying for the pool store owners 26' Open Fisherman, or Hummer.
Makes a difference.
This place is like the show CHEERS!... we're all one big disfunctional family here.
