Is a sump like this worth it? https://www.customaquariums.com/product/3600gph-reef-83-aquarium-sump-package/ or any of the customaquarium sumps? trying to see if its worth buying a sump vs DIY'ing - I think buying might be the way I go only b/c as long as I oversize it it should handle any upgrades etc in the future vs having the seal/diy a glass sump ?? Thoughts ?
