Is my cell dying?

Memory's a little fuzzy since it was last fall, but I think it was about 2 lbs (1/2 of one of the "large" boxes of arm and hammer). Since I had that acid spill I keep several boxes on hand at home "just in case".

Thanks. I might give that a try the first time and see how it goes.

Like you, I don't want to put the calcium back into the pool, but like was mentioned, it's probably an very insignificant amount. At least I know my options now.

Forgive me but that seems like a lot of trouble for so little CH compared to what is in the pool. 400 ppm CH in a 20 k pool is over 66 lbs. The amount on the cell is probably less than a couple of grams. Close to a 15000:1 ratio. Fill water probably adds more than that in a day.

A couple grams is all? Put that way it does seem that putting it in the pool is the easiest thing to do without any real consequence.

I greatly appreciate y'all sharing your experience using both methods.

Agreed. I guess I didn't consider how little would be on the cell. Thanks for the tip, mas985.

UPDATE

I cleaned the cell today with the acid solution as recommended (4 parts water, 1 part muriatic acid: 4 cups water and 1 cup acid turned out to be just about the right amount to fill the T 15 cell). There didn't seem to be much bubbling, so I'm guessing there really wasn't much calcium on the cell plates. I checked the controller readings after reinstalling the cell and didn't notice anything different. I'll keep any eye on CL level to see if the cell is working more effectively or not (based on the unchanged controller readings, I suspect not).

I'll post an update once I see if the cell's efficiency has changed or not.

Thanks for all the feedback and help.

PS - Btw, I just dumped the used acid solution back into the pool.
