We are still trying to decide between a Gunite vs Liner pool. So we have started taking quotes for both PBs. Yesterday a line PB came and told us that maintenance costs of a Gunite pool are about 2-3 times the cost of a liner pool. (Ignoring the liner change and eventual plaster redone/fix) he was talking more about daily maintenance costs. He said to maintain proper PH balance, we have to put much more chemicals than we would in a liner pool. It would require more heating too because Gunite does not offer any insulation properties, etc. Since this is the first time we are doing this, we have no idea how to quantify this.
Can someone give us some estimate of if this is actually true? Why would we have to use so much more chemical to maintain the PH balance? Would that be safe for us? And also in terms of maintenance costs, how much are we talking per month? If we use SWG, are we talking $500/month during months of its operation? Or more. We are in the North East near Boston, MA. We getting a little confused withe the sales talk
