Alright so I'm just about ready to start ordering plumping and drilling supplies for my breeding setup. I'm a total noob when it comes to PVC and plumbing so I need some help. My system will consist of 5 ten gallon tanks (turned so their sides are facing forward for more room) and one 30 gallon tank on the end. I plan to drill each tank in the upper front corner where I will place an elbow for draining that will lead to one central sump. What size bulkhead should I drill on each tank? Also, the water will be pumped back to the aquariums from one pump and each tank will have it's own ball valve to control flow back from the sump. What size PVC should my return line be? One more thing, can anyone recommend a diamond drill bit to order are the more expensive ones really better?
