Around here, and online the aquarite units with the 40k gal T-Cell go for about $1,000. $2k for installation seems seriously excessive. If you're comfortable wiring the unit into your pool's breaker panel, and plumbing it in then DIY. Call around for some different quotes if you're not.

Basically, if you have a section of exposed piping you are going to install the unit there. Or you may have to add some piping to plumb the generator into. The cell has a long cord that connects to a control panel that gets mounted on the wall. That panel gets wired into the circuit with your pump and timer. This way, when the pump is on the generator is on. That's about it.

Having said that, a SWCG can make pool sanitation very easy and hands off. It is unlikely to ever save you money. Add up how much you're going to spend in say 2-3 years on chlorine and see if that comes to the price of your swcg.

Also, the hayward swcg wants 3800ppm of salt. In your pool that's about 32 40# bags of salt. They go from $5-$10 each (at least around here, they do). So add another $160-$320 for salt. It sounds like you already have a fair amount of CYA in your pool. I can't remember exactly what the hayward unit recommends but I think it's like 80 or 90ppm CYA. You'll have to add acid regularly to keep pH down. I add a quart or less about once a week, and tend to buy acid by the case for convenience. Adding borates to the mix can help decrease the pH rate of change for less frequent acid doses. It means larger doses less often.


I have the 40k gallon hayward cell on an 11.5k gallon pool. I run the cell at 25% most of the time and mine is nearly 5 years old. You're going to end up running at a higher level with a 30k gallon pool so you'll get less life from the cell.
