A 100-gallon fish tank opens the door to truly breathtaking aquascapes, exotic species, and long-term stability.

Why Choose a 100-Gallon Aquarium?
100-gallon tanks offer maximum versatility and stability for advanced hobbyists. They’re large enough to support big fish, planted aquascapes, or even saltwater reefs, all while offering more forgiving water parameters compared to smaller tanks.
Benefits of a 100-Gallon Tank:
- Supports large fish like Oscars, Angelfish, or Cichlids
- Stable water chemistry, even with bio load changes
- Space for aquascaping with rocks, driftwood, or live plants
- Suitable for freshwater or saltwater setups

Glass vs. Acrylic for 100-Gallon Tanks
| Feature | Glass | Acrylic |
|---|---|---|
| Weight | Very heavy | 50% lighter |
| Scratch Resistance | Resistant | Scratches easily but can be buffed |
| Clarity | Good (can have green tint) | Excellent optical clarity |
| Durability | Brittle under impact | Impact-resistant and flexible |
Verdict: Glass is ideal for those on a budget and concerned about scratches. Acrylic is better for clarity, weight, and durability in the long run.
What to Consider Before Buying

- Ensure your floor can support the weight
- Choose a stand designed for this tank size
2. Filtration System
- Canister filters (e.g., Fluval FX4/FX6) or sump filtration are ideal
- Aim for turnover of 5–10x tank volume per hour
3. Lighting
- LED lighting is energy-efficient and customizable
- Use full-spectrum lights for planted tanks or reef tanks
4. Heating and Aeration
- Use 2 heaters (each 150W–200W) for consistent temp
- Add an air pump or wavemaker for circulation
