My valve is the Fleck 5600 SXT. Salt tank measures 14" x 16" X 32" tall

The white tape mark on the salt tank shows my water line after regen this morn.

It ran for 8 minutes before almost overflowing (and being shut off by the float) at .5 gpm. So it can handle 12 lbs of salt but that would be the max.

Gary, I agree with everything stated. I wasn't sure if I should lower to 36K so thanks for clarifying. A few questions; Lowering the time of the brine fill to 8 min at .5 gpm will effectively set it to 12lbs of salt correct ? And since I just regenerated with Iron out this morning should I do it again this evening or omit it from the back to back regeneration.

Thanks for all the help.

you need to check your refill rate. It looks like you are flowing a lot more than .5 GPM.

My math is a little rusty on rectangular tanks but here it goes.

14x16=224 cu. inches per inch of height, so 8" would be approximately 1 Cu. Ft, or 7.5 gallons, , you need 4 gallons so you would have approximately 5" of water, times 2 for salt displacement, add 2 inches for the aircheck, you should have approximately 12" of salt in the brine tank.

The picture of your systems is also a good example of why round brine tanks are preferred to square, unless it is pregnant. :)

Can someone else here recheck my math? I dont have time today to pull my cheat sheets.

You need to remove the tube at the brine tank and measure it in the refill position. Be sure it is flowing at .5 GPM. I am guessing it is exceeding that considerably. Unless my math is totally wrong.

LOL

I have a square tank and it doesn't bulge like that. They must be making them thinner now.

I sold 15 x 17"rectangular salt tanks and never had them change shape. I think they may have been made by Clack.

How much salt do you have in it? Otherwise see my last reply..

The best would be to do the 2 regens with the max salt dose of 23 lbs but, do another one with IO tonight and see how it does for a few weeks with the new programming.

I suggest you buy hardness and iron tests somewhere and test each week for a month or so just before it regenerates. If you see hardness or iron getting through, then do the 2 manual regens at 23 lbs.

Also do the IO with a 1/2 cup in a gallon of water poured into the water in the salt tank once every 4-6 weeks.

If you are going to do the math on the salt tank then for accuracy sake i should tell you the tank is obviously tapered and the bottom is actually smaller at 12" x 14" and I measure the water line at 21". Even using your displacement value and the new measurement, I still only come up with 14" of height instead of 12". Still a HUGE difference from the 21" that I have. I would then question the accuracy of "times 2 for salt displacement". My guess is the salt on the bottom is probably packed in pretty tight and displacing more water than that and that is why you are seeing the big belly in the middle. But I am only guessing and will defer to the thoughts of others on the board.

Have you checked for an air leak somewhere in the brine system? I would think that if the brine tank has that much water in it when a cycle starts, you would get salty water after a regen.
