I am thinking about drilling my ecopico to hide all the heaters and powerheads. If I used 3/4" diamond bit, what is the right size bulkheads that I must buy?
thanks

I don't think I've seen a bulkhead that small. I am sure they make them, just not standard. The 3/4" Bulkhead requires a 1 1/2" bit. A 1" bulkhead uses a 1 3/4" drill bit.

Look at the bulkheads on bulkreefsupply.com they've got a chart that shows their dimensions and required hole size. You might find slightly different size requirements for differently branded bulkheads.

I would suggest buying the bit and the bulkhead together so that you know it will be correct. Both BRS and www.glass-holes.com can fix you up
