I currently have the pool in my signature. With chlorine prices constantly rising, I want a SWG system. I've had one before so I have a general knowledge of them. I'm looking for recommendations on brand/models, BUT, I don't wanna spend $1,000 on one. I'm looking in the $200-400 range if possible. The one I have in mind now is the Intex QS1200 which it says is good for up to 15k gallons. Would that be sufficient? Pros? Cons? I will add I'm in South Texas where summers are brutal, so it will need to keep up the chlorine production.
