What To Look For In A 5 Gallon Aquarium Kit

Don’t get the wrong aquarium kit! Here’s how you can make the right choice…

Freshwater Or Saltwater Tank

Both are possible, but freshwater is a better option. Freshwater tanks give you more options at 5 gallons, including in fish choice. Maintaining tiny freshwater tanks is also easier because the water quality parameters are not as sensitive as those in a saltwater tank.

Saltwater tanks get more complex the smaller they are. If you want to try a 5-gallon saltwater tank, reef tanks and invertebrate tanks are easier than stocking fish. However, you can also set up a fish tank if you get the right type of fish that will thrive in a small space.

5-Gallon Aquarium Kits Review

 

No matter which type of tank you’re going for, selecting your inhabitants is a big part of choosing the right tank. If you want a vibrant, fully stocked tank, you’ll get a fuller load with a freshwater tank than a saltwater tank.

Acrylic Versus Glass

Five-gallon tanks are available as both acrylic and glass in different shapes and designs. Each type of tank is clear and will hold its shape in a 5-gallon size. However, there are still some distinct differences between each.

Acrylic tanks tend to scratch easily. You have to be careful when you’re cleaning the tank, and you may have to select your substrate and decorations carefully. But, acrylic tanks are very durable and won’t chip or crack under normal circumstances.

5-Gallon Aquarium Kits Best Review

Glass tanks are cheaper than acrylic nine times out of ten. They’re also more likely to remain clear over time instead of clouding up or getting scratched. The downside to glass is it’s not as durable as acrylic and is more likely to chip or crack over long periods of time.

Filtration

Not all 5-gallon tank kits come with filters, but they all should. Even if you’re housing only one fish in your tank, a filter will improve water quality. Better water qualityimproves the health and lifespan of whatever’s in your tank.

Filters for nano tanks need to have the right balance of power. If they’re too strong, they’ll overpower the tank and create too much disturbance. If they’re too weak, they won’t do anything and you’ll still have to do a lot of water changes. Get a filter that matches your tank size.

Kit Contents

There’s little consistency when it comes to aquarium kits for smaller tanks. With 5 gallons, you’re likely to get the tank, hood, and maybe a filter. You may need more than this.

If you plan to keep tropical fish and you don’t live in the warmer area, you may need a heater. You may also need an LED light, especially for a 5-gallon nano reef tank. Other kit pieces are nice extras but are not a requirement.

Tank Shape

You have a lot of choices when it comes to the shape you want for a 5-gallon tank. This is almost entirely an aesthetic choice for you because it won’t make a difference for the fish. In a 5-gallon tank, there is a lot of evaporation and a limited area to swim no matter what.

Conclusion

For a good, simple kit, go for the Marina LED Aquarium Kit. It’s a solid aquarium kit that just needs the addition of a heater to work well for most tropical freshwater fish.

If you’re in the market for a small tank that’s a bit better for beginners, the GloFish 5 Gallon Crescent Aquarium Kit is a fun choice for kids and families.

Whatever you choose, make sure you base it off the facts. Learn about what makes the best 5-gallon fish tank kit different from the rest and pick what suits your needs the most.
