Many hobbyists have been waiting for the return of AquaMaxx's HOB-1 and ConeS skimmers, but we've got some other goodies back from AquaMaxx that you should definitely consider (rated 5 stars by customers!). First up: AquaMaxx GFO and Carbon Media Reactors are available in both the Standard and XL sizes. These versatile reactors are capable of running several different types of filter media, from activated carbon and granular ferrous oxide to resin and nitrate-reducing media. Next we've got AquaMaxx BioMaxx BioPellet Reactors back in stock in both the Standard and XL sizes. BioPellets initiate a more efficient denitrification process that removes nitrate and phosphate from aquarium water to prevent algae growth or harm to invertebrate and coral. You can view these reactors along with the AquaMaxx filter media you can run inside them here.
