I'm looking to get in the saltwater fish/coral keeping hobby and i'm trying to save cost by building my own sump and refugium. I am wondering what size sump/refugium would be a good for a 90gallon tank . And also if someone could help me with plans for the build including dimensions. I will be sure to include picks of all the work I do but I'm looking to get started as soon as I can and I would really appreciate it if someone could help with some custom plans.
