I had an older model of the tank. Don't know if there are any design
changes on your model.

I think I used ammonium persulfate  (may have been sodium)  in the tank.
Worked well, but does need a fair amount of enchant in the sump of the
tank, also the enchant has a limited life span once it's dissolved in water.

 I had problems with the magnetic impellers on the pumps falling apart. Get
spares.  Don't store enchant in the tank. Especially any enchant that tends
to crystallize.
 Think it permeates the sintered magnetic material on the impellers and
cracks them. (a lot of guesswork here).
