I didn't wanna mess with building my first sump so I bought a premade one. Bit more pricey but saved me alot of headaches. LOL Here's a link to one that would work with your tank, it has a refugium as well so that's a plus.
Eshopps Refugium R-100, 75-125g, 2nd Generation - AquaCave.com
After the first sump I bought I have made my new ones out of regular fish tanks.
Alot cheaper and you can customize it.
180g Reef - 60g Rimless Reef -90G FOWLR- 125g Malawi Cichlids- 40b REEF- 34g Fresh Planted-working on- 20L FOWLR- working on
I have a mix of many different saltwater fish amongst my tanks, but I love my Tangs most of all.
