The Ultimate Fish Tank Buying Guide: Bringing the Aquarium Home
Choosing the right fish tank is exciting! A beautiful aquarium brings life to any room. This guide helps you pick the perfect home for your underwater friends.
Key Features to Look For
When you shop, focus on these important parts of the tank setup:
- Size and Volume: Tanks are measured in gallons. Bigger tanks are easier to keep clean and stable. Small tanks look nice but require more frequent water changes. Always choose a size appropriate for the fish you plan to keep.
- Lid/Hood: A good lid keeps fish from jumping out. It also holds the light fixture securely. Make sure the lid has openings for feeding and equipment wires.
- Filtration System: This is the tank’s kidney. It cleans the water. Look for filters rated for a tank slightly larger than yours. Good filtration keeps your fish healthy.
- Heater (If Needed): Tropical fish need warm water. A reliable, adjustable heater is essential. Check that the wattage matches the tank size.
Important Materials Matter
The material of the tank greatly affects its look and durability.
Glass vs. Acrylic
Most tanks are made from one of two materials:
- Glass Tanks: Glass is very scratch-resistant. It stays clear for a long time. However, glass tanks are heavy and can crack if dropped or bumped hard.
- Acrylic Tanks: Acrylic is much lighter than glass. It resists shattering better. A downside is that acrylic scratches easily. You must clean it gently.
The Stand and Support
Water is heavy! A 20-gallon tank weighs over 200 pounds when full. Always buy a stand designed specifically for aquariums. A weak table might collapse, causing a big, wet disaster.
Factors That Improve or Reduce Quality
What makes one tank better than another? It often comes down to construction and included extras.
Quality Boosters:
- Seams and Seals: Look closely at where the glass panels meet. Strong, even silicone sealant indicates good construction. Poorly sealed tanks leak.
- Built-in Systems: Some kits include everything you need: filter, heater, and light. These integrated systems often fit together perfectly.
- Clear Viewing Panels: High-quality glass or acrylic offers distortion-free viewing. You want to see your fish clearly!
Quality Reducers:
- Cheap Plastic Components: Flimsy plastic lids or cheap filter housings break quickly.
- Inadequate Lighting: If the light is too dim, plants will die, and your fish colors will look dull.
User Experience and Use Cases
Think about who will use the tank and where it will go.
For Beginners:
New fish keepers should start small, maybe a 10-gallon kit. These starter kits usually include basic, necessary equipment. They offer a simple way to learn about water cycling and maintenance.
For Experts:
Experienced hobbyists often prefer larger, rimless glass tanks. They might buy specialized equipment separately. Experts focus on tanks that offer the best viewing angles for complex setups like planted aquascapes.
Remember, a good user experience means low hassle. Easy access for cleaning and quiet equipment are big wins for daily enjoyment.
Fish Tank Buying Guide FAQs
Q: What is the easiest size tank for a beginner?
A: A 10-gallon or 20-gallon tank is generally easy for beginners. Larger tanks (like 55 gallons) are more stable once you learn the ropes, but they cost more upfront.
Q: How often must I clean the filter?
A: You should clean or replace filter media every two to four weeks, depending on how dirty your tank gets. Never replace all the filter media at once, as this removes beneficial bacteria.
Q: Do I need a heater for every fish tank?
A: Not every tank needs one. If you keep cold-water fish like goldfish, you do not need a heater. Tropical fish, like tetras or guppies, require a consistent temperature provided by a heater.
Q: What is “tank cycling”?
A: Tank cycling is the process of growing good bacteria in the filter and substrate. This bacteria breaks down harmful fish waste (ammonia). You must complete this process before adding fish to prevent sickness.
Q: Can I put any fish together in one tank?
A: No. You must research compatibility. Some fish fight, and some fish get too big for small tanks. Always check the adult size and temperament of any fish before buying them.
Q: How important is the tank lid?
A: The lid is very important. Many fish jump when startled or stressed. A secure lid prevents fish from escaping and keeps debris out of the water.
Q: What is the difference between filtration types?
A: There are three types: mechanical (catches debris), chemical (removes odors/toxins), and biological (the most important, houses good bacteria). Good filters combine all three.
Q: How do I clean scratches on an acrylic tank?
A: Acrylic scratches easily. Use only soft cloths and approved acrylic polish or scratch removal kits. Never use paper towels or abrasive sponges on acrylic.
Q: Should I buy a complete kit or separate components?
A: Kits are great for beginners because they include matching parts. Experienced keepers often buy components separately to ensure they get high-quality filters and lights.
Q: How much light do planted tanks need?
A: Planted tanks need stronger lighting than tanks with only fish. Look for LED lights specifically designed for plant growth. Plants need several hours of good light daily.
