i am ready to install my plumbing this weekend. I have the aqueon mega flow kit that came with my aquarium and the bulkheads have the hose barb ends on them not a slip style. I have been racking my brain to come up with a super simple plumbing plan that does not contain to many different connections. With a variable speed return pump do I really need ball valves? Can I get some pvc fittings that will match the bulkhead threads in order to convert them to slip style?
The bulkheads ale the ones in this pic if you can see them.
