nemirn Posted March 18, 2010 Share Posted March 18, 2010 I plan getting a 20gal tank drilled and installing a DIY overflow box. First some questions: What size should the hole be? Where can I buy bulkheads locally? Thanks! Quote Link to comment Share on other sites More sharing options...
Derek Posted March 18, 2010 Share Posted March 18, 2010 You can get bulkheads from Fishy Business on North Burnet, just north of Braker. I got one there for six bucks. Shane would be able to tell you how big the hole would need to be drilled. Quote Link to comment Share on other sites More sharing options...
