Top Fin 37 Gallon Aquarium

My Journey Into the Fascinating World of Fishkeeping

As someone who’s always loved animals and nature, I’ve been intrigued by the idea of having an aquarium for years. There’s something so mesmerizing about creating a tiny aquatic ecosystem right in your own home. But aquariums always seemed complicated, expensive, and time-consuming to maintain. However, after doing extensive research on beginner-friendly aquarium options, I finally decided to take the plunge and set up my very first tank – a Top Fin 37 gallon aquarium!

In this blog, I’ll take you through my journey of setting up this medium-sized tank from start to finish. From assembling the tank and choosing equipment to cycling, adding fish, and daily maintenance, I’ll share everything I learned along the way as a new fishkeeper. Whether you’re considering a Top Fin 37 yourself or just starting out with aquariums in general, my goal is to provide a helpful, honest guide so you can avoid the mistakes I made. Let’s dive in!

Key Considerations for Purchasing and Setting Up the Top Fin 37 Gallon

Once I settled on getting a 37 gallon tank, which provides ample space for fish while still being manageable for a beginner, I needed to ensure I chose the right additional equipment and set everything up properly to give my future fish the best home possible. Here are some key steps to take:

Tank Location – Pick a Sturdy, Level Surface

The Top Fin 37 gallon tank is deceptively heavy when filled, weighing over 300 pounds! So the first consideration is placing it on a strong, level stand or cabinet that won’t bend or buckle under the weight. I chose a basic metal tank stand designed specifically for 37 gallon aquariums.

Make sure the surface is level – even a slight tilt will cause the tank silicone to flex over time, potentially leading to leaks. You don’t want 37 gallons of water ending up on your floors!

Filtration – Adequate Flow Rate is Crucial

Filtration is essential for maintaining water quality by removing waste, debris, and keeping water chemically balanced. For a 37 gallon tank, experts recommend a filter or combo of filters rated for at least 185 gallons per hour (GPH) flow rate. This ensures water circulates through the filter around 5 times per hour.

I opted for two smaller hang-on-back filters positioned at opposite ends of the tank rather than one large filter to maximize flow. I’d recommend the Top Fin SilenStream 75 as an affordable option.

Heater and Thermometer – Keep Water Temperature Consistent

Most tropical fish require water temperatures between 76-82°F. The included 50 watt Top Fin heater is perfectly sized to keep a 37 gallon tank in this range. Use a thermometer to monitor the temperature – fluctuations can stress or even kill fish!

Substrate – Gravel or Sand?

For substrate, you can use gravel, sand, or a combination. Sand looks more natural but requires careful cleaning to prevent toxic gas buildup. I went with a natural gravel substrate about 2 inches deep. Make sure to thoroughly rinse the substrate before adding it to the tank to get rid of debris.

Decorations – Give Fish Places to Explore and Hide

Decor like rocks, driftwood, and artificial plants make the tank more visually appealing while also giving fish areas to explore and feel secure. Just be sure decorations are aquarium-safe and thoroughly washed/disinfected. I added a centerpiece rock formation and some silk plants.

Cycling – The Most Vital Step Before Adding Fish

Now that everything was set up, it was time for the nitrogen cycle to establish beneficial bacteria that convert toxic ammonia and nitrite into less harmful nitrate. Completing this cycle is crucial or fish will get sick or die when added too early.

For a fishless cycle, I added a few drops of pure ammonia daily to feed the developing bacteria. I used the API Master Test Kit to track ammonia and nitrite levels until both dropped to zero, indicating the tank was ready for fish – which took around 5-6 weeks. Patience is key!

Selecting Fish for the 37 Gallon Aquarium

The fun part – stocking my tank with beautiful, active fish! A diverse community of compatible species makes for the most vibrant, interesting aquarium. With 37 gallons, I could choose fish requiring 20-30 gallon tanks. Here’s what I went with:

• Centerpiece fish: 1 Pearl Gourami
• Schooling fish: 8 Harlequin Rasboras
• Bottom dwellers: 5 Corydoras catfish
• Algae eaters: 4 Otocinclus catfish

This provided a great mix of colors, behaviors, and habitat zones occupied without overcrowding. I was careful to select fish suitable for a community tank and with similar water parameter needs.

Maintaining a Healthy Environment

Caring for an aquarium doesn’t stop after it’s fully set up – maintenance is crucial for long-term success. Here are some best practices I followed:

• Partial water changes of 25% weekly to replenish minerals and reduce nitrate buildup
• Filter cleaning/replacement monthly to ensure optimal water flow
• Checking and adjusting water parameters like pH, hardness, etc. to meet fish needs
• Feeding a small amount 1-2 times daily, only what fish can consume in a few minutes
• Wiping down the glass during water changes to remove algae buildup
• Testing water quality with the API test kit to catch any spikes in ammonia, nitrites, or nitrates

Enjoying the Relaxing Hobby of Fishkeeping

As a new aquarist, the Top Fin 37 gallon tank has been an amazing introduction into the enjoyable, rewarding hobby of fishkeeping. Though the initial setup took time, effort, and patience, I can now relax and admire the brilliantly colored fish swimming through the aquatic world I’ve created.
