In all systems, begin with a ratio of 150 g Xport Bio Cubes per 300 US-gallons (1,136 L) in system. If plants and/or zooxanthellate invertebrates (e.g. corals, clams, etc.) appear to react negatively to the use of Xport Bio Cubes, it may be an indication that nitrogen is being removed too aggressively; NeoNitro or FlorinGro may be employed to provide nitrogen as nitrate, and feeding with the appropriate foods is necessary for all zooxanthellate invertebrates.
