Reefer 250. I passively run about 2 TBSP in a mesh bag I just throw in the sump with some carbon whenever I think about replacing it. I don't really think anything will make it change color except copper so if it's absorbing other things, I just try to change it every few months to keep it relatively fresh and then regen it once before tossing it.
Ok. Sounds great. Do you recommend a good mesh bag or know where to get them?
Kinda been looking for a good bag for carbon, but now it will be carbon and a little cuprisorb.
