What sells it / What holds it back

✓ Pros

✓ Truly turnkey — uncrate, plumb a return pump, you're running. No DIY drilling.

✓ Rimless starphire glass — gallery-quality clarity

✓ Integrated sump + ATO reservoir saves the 'where do I put the sump?' headache

✓ Used resale market is strong — easy to upgrade or downsize without losing money

✗ Cons

✗ Stock plumbing is silent but undersized for heavy bioload — many reefers swap to 1.5" return

✗ ATO reservoir is small (10-20 L) — kalkwasser dosers need an external jug

✗ Single overflow / single return — limits flow vs custom-drilled tanks

✗ Stand cabinet doors are MDF veneer; warps if water dripped + not wiped
