Considering switching to salt generator

Go with the T-15 cell. It will run on a lower output percentage. For Goldline units that means for every 100 minutes of pump time the cell will run for a certain percentage of that time and be off the rest of the time. The cell will last longer, you won't have as fast a pH rise, and there should be slower scale formation in the cell. I am actually running a T-15 cell on a pool that is under 7K gallons with no problems whatsoever! (I have an older Aqualogic that only accepts T-15 cells. Only the newer units can accept T-9 and T-5 cells so make sure yours can if you decide to go with a smaller cell.)

Thanks for the great info. I'm inclined to go with the larger unit for the reasons cited.

I'm using a T-15 on a 12k gallon pool, no problems at all. I've been maintaining about 3.5ppm chlorine with it set at 30% and running for 6 hours a day (4pm-10pm). I'm a bit lower than the manufacturers recommendation for CYA so I could probably drop my setting a bit if I corrected that.

When I bought my house with pool the control board was broken, and I ran the pool for a month or so without the swcg. I can't compare the swcg to other brands or models but it definitely makes things easier than standard bleach. You just have to stay on top of pH; I add acid every week or so to keep it in check.
