Whirlpool whes48 softener black grit

[ryker1]

I live in Florida, on a well. March of this year replaced old Sears softener that failed with the Whirlpool, so about 9 months new. I have run their cleaning agent on a regular basis, and I keep track of the regen. of the softener on an excel program along with pool data, and it regens. about every 6 to 7 days for our water usage. I let it go auto to decide when. Before the water enters the softener, I have a 1000/mesh Rusco filter, and then a Whirlpool charcoal whole house filter that filters the water. I have (tested yearly), a 1 ppm/iron, and a 10 on the hardness scale.

For every regeneration, it has been normal, until this last one. Went away for thanksgiving, so noticed when we got home, it regenerated on a longer time frame, since we were not there using water. Not sure how many days, but at least 10-12. Never went that long. As you know, this softener has the resin tank inside the salt tank. When I checked the softener upon returning, I found a dark ring around the resin and the softener tank, at a (I'm sure), height of the water on the last regen. On my fingers, and rubbing it on a paper towel, it is gritty. Very fine grit. I don't think it is oily, but the grit makes it seem that way. I have read that it could be magnesium, from the water, but not sure.

Should I be concerned, and/or, remove the salt and do a good cleaning. Or just a couple of regenerations close together. If not enough info, I'll supply whatever is needed.

Thanks.

I have a 1000/mesh Rusco filter,

That is unusually fine. http://www.rusco.com/images/productos/especifications/MeshSizeSelection.pdf What does that collect?

and then a Whirlpool charcoal whole house filter that filters the water.

Maybe that is decomposing somehow, and your material is charcoal?

I have read that it could be magnesium, from the water, but not sure.

You are thinking of manganese.

I have the 1000 mesh filter for sand, grit whatever, it's a shallow well, about 75 feet. Everything in Florida is sand. Should have seen when they dug the pool. The other filter, is an approved whirlpool filter, changed every 2 months, (to help the taste and the odor), even though they last for 6 months. Approved by whirlpool. And yes, that should be I'm reading or thinking about manganese.
