Reef Ball Specifications for Comparison to Other Reef Material Solid Weight Equivalency- (simply stated, if the Reef Balls were poured solid without holes or a center bladder, this would be the weight of the structure). This is useful for comparing raw tonnage requirements for a similar project using, for example, limestone boulders. Oyster Ball is equal to 100 pounds of solid reef material Lo-Pro Ball is equal to 200 pounds of solid reef material Bay Ball is equal to 1,150 pounds of solid reef material Pallet Ball is equal to 5,225 pounds of solid reef material Reef Ball is equal to 9,980 pounds of solid reef material Surface Area Equivalency-(simply stated, how much surface area for marine growth is available (macro) and how much texture is available for bacteria, micro-algae and other micro-organism colonization (micro). This is useful to determine the real carrying capacity in terms of the bio-fouling communities. The number of holes is important in determining the amount of reef fish habitat created. Oyster Ball has a macro (raw "smooth") surface area of 3 square feet Lo-Pro Ball has a macro (raw "smooth") surface area of 6 square feet Bay Ball has a macro (raw "smooth") surface area of 30 square feet Pallet Ball has a macro (raw "smooth") surface area of 75 square feet Reef Ball has a macro (raw "smooth") surface area of 130 square feet Oyster Ball has a macro (raw "smooth") surface area of 48 square feet Lo-Pro Ball has a macro (raw "smooth") surface area of 96 square feet Bay Ball has a micro (texture) surface area of 480 square feet Pallet Ball has a micro (texture) surface area of 1200 square feet Reef Ball has a micro (texture) surface area of 2080 square feet Oyster Ball as 3-8 small holes (diameters 2-5 inches) Lo Pro Ball has 6-12 small holes (diameters 2-5 inches) and 1 or 2 Fish holes (diameters 6-12 inches) Bay Ball has 14-18 "fish" holes (diameters from 6-14 inches) Pallet Ball has 23-28 "fish" holes (diameters from 6-18 inches) Reef Ball has 29-34 "fish" holes (diameters from 7-22 inches) Biomass Carrying Capacity-This is an estimate based on a variety of studies of the approximate carrying capacity in terms of fish bio-mass. Oyster Ball has a carrying capacity of approximately  10 pounds Lo-Pro Ball has a carrying capacity of approximately 20 pounds Bay Ball has a carrying capacity of approximately 100 pounds fish/year Pallet Ball has a carrying capacity of approximately 250 pounds fish/year Reef Ball has a carrying capacity of approximately 425 pounds fish/year
