What the AI looks for in Aquariums
- Stand compatibility
- Stand must support the full filled weight and match the tank's exact footprint Water is heavy, and an uneven or undersized stand stresses the seams.
- Glass vs acrylic
- Glass for scratch resistance; acrylic for lighter weight and impact resistance Acrylic scratches easily during cleaning, while glass is heavier and can chip.
- Rimmed vs rimless
- Rimmed for standard lids and hoods; rimless needs thicker glass and an aftermarket lid This decides what lighting and lids will fit.
- Footprint
- Prefer long and breeder sizes over tall ones More surface area and swimming length for the same volume.
Brands that matter
- Aqueon: Standard rimmed glass tanks in common sizes.
- Ultum Nature Systems: Rimless low-iron tanks.
- Waterbox: Premium rimless and reef-oriented systems.
- SeaClear: Acrylic tanks.
What to avoid
- Placing a tank on furniture not rated for its filled weight.
- Used tanks with peeling or cloudy silicone seams.
- Tall narrow tanks for active fish.
