Hello, I am upgrading my 29 Biocube to my 90 gallon on account of my freshwater fish I had for four years passed away last evening. Anyways, I am looking to make a sump for my 90 gallon tank. I've had a 65 gallon saltwater a few years back and it was SO LOUD, I must have done something wrong. I am getting the tank drilled Monday with 3/4" bulkheads. Can someone please provide a site or step by step in how to do the plumbing for the sump? I used PVC pipe on my old tank, and I am thinking that perhaps silicone tubing would be a better choice because of its flexibility? Any help or advice would be greatly appreciated. I'm hoping to have the sump all set up mid week.
