Dr Bruce, I extrapolated sizes and weights of YP to come up with somewhere close to 9.36g/L (1.246oz/gallon, 35.36grams/gallon). Currently you have about 187 oz (5305g)of YP in the 150 gallons. Cecil may be able to provide some "normal" (light, medium, & high) RAS carrying capacities. If not I can look them up.
