In this guide, I’ll be showing the steps to building a DIY sump tank for your saltwater aquarium.
So I recently purchased a 65 gallon fish tank to start my venture into the world of saltwater reefs. After much reading and advice from the local fish stores, I started to get the gist of the things I needed to do. I picked up a used setup for a great price off Craigslist and after much research I decided that a sump tank was going to be the next thing on my to-do list. I just went ahead and got a 20 gallon tank and some pieces of glass cut at the local glass/window shop.
