I have a Reefer 250 which is 65g total. I added a single Red Sea Nanomat to my first sock holder and it's doing great even though it's suggested for 50g or less. That said, it is lasting only 2 weeks. It is supposed to last 2-4 weeks according to RS. I'd like it to be on the higher end of that range so my question is if I added a second Nanomat to the 2nd sock holder, would that make each one last longer than 2 weeks? Would adding the 2nd increase the time both rolls lasts? I don't want to have two Nanomats that I have to change every 2 weeks. Anyone with an idea about what happens if you have two mats?
