hmmm but i already bought the CC and already build the Undergravel Jet for my tank. The power head i bought is too strong to just run on its own.. its 800gph!!! also i had this crazy idea of going to the beach and catching my own fish? can i do that or will the fish just die? also will the fish that i get from the ocean contaminate my LS, LR, and everythign in general???
