Stainless separation tank - going to salt

[doofus57]

I'm going to switch over to salt in a week or so and have a Pentair fiberglass DE filter and use fiberclear. I've always backwashed into a stainless separation tank and have heard different stories about whether the stainless tank will rust out quickly or not. I would use a backwash hose, but it would have to be 180 feet long. Should I keep the separation tank and see how it holds up eliminate it and go to using a 180' backwash hose?

Pool is 36k gallons, pebble-tec finish, two speed pentair pump, 60 sq ft Pentair DE filter running fiberclear.

How have you been chlorinating in the past? Sodium Hypochlorite and trichlor both add salt to your pool water. Likely your salt level is higher than you think unless you recently drained and refilled your pool. The salinity of the pool water with a SWCG is only 3000 ppm or so. Not high enough to rust your tank any quicker than your pool water in the past would.

Poor quality materials weather from moisture. If its held up this far, it will likely do fine. The entire arguement against salt pools hinges on the salinity difference between 5% and 10% of seawater.

Getting a K-1766 salt test kit and use it for an accurate baseline before adding any salt is a must.
