Tropical Science Labs ATCMCL520 Marine Clean, 16-Ounce
Increases oxygen availability while cutting down on time consuming maintenance and reducing wear and tear on expensive filtration systems. Marine-Clean is a very high-density blend of non-pathogenic, heterotrophs that keep the aquatic system clean. Just because you don't see "sludge" doesn't mean it's not there in the form of natural organics and suspended debris that eat up precious oxygen of a marine system.
