Looking to upgrade, just about grown out of Prostar 90. Really like the idea of armored seams but only production brand I’m aware of that uses them is Red Sea. I’m looking for 60-72” long, 24”-30” wide, and 20-23” high. Also would prefer an external overflow. Planet makes pretty much 2 that would be perfect size with an external overflow. I see that they no longer make the crystalline series in all sizes, only 72&96” and the tideline are manufactured for them. Curious about peoples experiences with Planet aquariums. Also have been looking at the others mentioned in title. I like the idea of a fully customizable tank (glass cages) but time and cost are a concern however I have only ever heard great things about them. Open to suggestions, the tank will be sps dominate.
