All pool plaster finishes should last 20 years or more. However, some last only 5 to 7 years, and some less than a year before the plaster surface deteriorates, discolors, and looks terrible.
Why the difference? Very often, plaster…

Short story is I like sense and dispense. I think one of the greatest benefits is that the cell only runs when there is demand for sanitizer, as opposed to a preset percentage of the circulation cylce time. So my feeling is the life of the cell can be extended significantly this way, without having to be adjusting the chlorination all the time. It works the other way too: if there is a large sanitizer demand, the unit can be programmed to extend the circulation cycle until the sanitizer demand is met. If you run your pool systems year round like I do here in Socal, you can adjust the ORP down a little in the winter, and save even more cell life. As with any salt system, you need to make sure you have no leaks in the pool or you will be forever fighting salt levels, and the pH needs to be kept in the 7.4-7.6 range to keep the cell clean. If you use the sense & dispense 2 package to control pH with a CO2 tank, this will be taken care of for you. I installed pH control on all my systems. You can use the pH sensor to control a peristaltic pump for liquid acid, but I have not done this. ( I like the CO2 tanks, the customer pays for the tank and pays to get it refilled. The tanks are a little bulky, but overall, the customers feel more comfortable carting them around.) Installation is maybe 3 hours at the most, considerably less after you have done them a few times. I did one system on a commercial pool where the sense and dispense actually controlled 2 cells, that was handy. That's the brief. If you have questions, please feel free to post.

That Super Pump looks like about 67gpm at 50' whereas a Whisperflow will do about 110gpm. 24" sand filters are generally 60gpm on filter and 45gpm for a real nice backwash. So I was concerned that you would see channeling on filter and broken laterals during a backwash. Pump might be a tad oversized unless there is more head on the system but not anywhere what I was initially thinking.
Before putting a Salt system in double check your bonding. Then, triple check it. Then maybe look at one of the new anodes they are making to help lower any risks. I can't speak to the Sense and Dispense because I haven't used one yet, but I would assume it will be fine, equipment is itself is rarely a problem.
