Before You Buy
Key Buying Factors
01
Tank Material
We prefer low-iron glass for clarity and rimless designs for modern aesthetics. Plastic or standard glass can work but may show more scratches or green tint.
02
Stand Strength
A tank this size needs a stand rated for at least 50 gallons. Look for metal frames with leveling feet and weight capacity above 600 pounds.
03
Filtration Capacity
We recommend a filter rated for 2-3 times your tank volume. Submersible filters with adjustable flow are ideal for 50-gallon setups.
04
Tank Shape
Rectangular tanks offer more swimming space and better surface area for gas exchange. Taller tanks may limit light penetration.
05
Lighting
LED lights with low wattage (2-5W) are sufficient for fish-only tanks. For planted tanks, look for full-spectrum lights with higher output.
06
Compatibility
Ensure all components (tank, stand, filter, light) fit together. Check dimensions and weight distribution to avoid instability.
Living With It
Care, Cost and Maintenance
Water Changes
Perform 25% water changes weekly using a gravel vacuum. Use dechlorinated water matching tank temperature.
Filter Maintenance
Rinse mechanical media monthly in tank water (not tap water). Replace chemical media as recommended by manufacturer.
Tank Cleaning
Wipe algae from glass with an algae scraper. Clean decorations and gravel in tank water during water changes.
Pro tip
Always place your tank on a perfectly level surface. Use a spirit level on all four edges before filling. Uneven tanks can crack or cause stand stress.
Frequently asked questions
Can I use a 50-gallon tank on a regular desk?
No, 50 gallons of water weighs over 400 pounds. Only use a stand rated for that weight.
Do I need a heater for a 50-gallon tank?
Yes, most fish require stable temperatures. Use a heater rated for 50-100 gallons.
How often should I clean the filter?
Rinse mechanical media monthly, and replace chemical media as directed. Do not clean all media at once.
Can I keep turtles in these tanks?
Only if the tank is designed for turtles (e.g., REPTIZOO). Regular tanks lack basking platforms.
Is low-iron glass worth it?
Yes, for display tanks. It minimizes the green tint and offers clearer viewing.
