I've decided to start with a 50gal livestock tank with possibly adding on in the future. What pump recommendation and what size bulkheads. At least to start my first one. tia
Well, the big thing you want is water *volume* flow and not velocity. Too much velocity and you'll blow the flesh off of certain species. I'd say if you used something between a Mag7 to a Mag12 and put the output of those pumps into multiple outputs you'd be set.
