Aquariums that are between 75 – 80 gallons are a great size for more experienced fish keepers – they’ll fit comfortably in most homes, but they’ll also allow for a good collection of fish, plants and even ornaments or decorations. We’ve created this guide to show you what we believe to be the best fish tanks at this size currently available on the market. But before we get into the more detailed guide, let’s start with a quick overview of what the best 75 – 80 gallon tanks are according to online reviews:

An introduction to 75 gallon aquariums.

The first thing to be aware of with a 75 gallon aquarium is that it’s a great size for beginners AND experienced fish keepers. Some people would describe a tank of this size as large – the reality is that 75 gallons is not actually that huge, and if you have the space for a tank of this size in your home, and you want to get serious about looking after fish – then you should absolute go for a tank of this size. But here are some important points to be aware of:

Dimensions & Weight

Looking at the most popular tanks at this size on the market currently, typical dimensions of a 75 gallon aquarium would be:

18″L x 48″W x 21″H

49″L x 21.25″Wx 19.5″H

48.5″L x 18.5″W x 21 3/8″ H

The weight will depend on the material – a glass aquarium at this size would likely weigh around 150lbs when empty, and could easily weight upwards of 800lbs when full of water. So before purchasing a tank at this size, make sure that you not only have sufficient room in your home to accommodate the dimensions outlined above, but also that you have strong enough flooring to support a tank full of water at the above weight.

Required Equipment

A 75 gal tank will require some pretty advanced equipment to keep it running and to keep all of the fish inside of the tank healthy and happy. So before we start recommending what types of fish you might want to keep in a tank of this size, here is what equipment you’ll need:

Filters

To keep a relatively large aquarium of 75 gallons in size clean, you need to make sure the filter you’re using is powerful enough to properly cycle all of the water in your tank, so it is properly removed of all toxins and other nasty stuff that might harm your fish. Some of the best filter brands we’d recommend for a tank of this size include:

  • Fluval FX 6 – this filter might seem a bit too large for a 75 gallon tank, but there is actually a great video on YouTube explaining why a filter of this type could be perfect, here is the video. 
  • Fluval 406 – this is an external canister filter and will fit on nicely to your aquarium
  • AquaClear 110 – this is a power filter and would be a great choice
  • Aqueon QuietFlow – this is a quiet but efficient filter

Heater

Similar to as with the filter, a heater needs to be large enough and powerful enough to ensure that every inch of the 75 gallons of water is heated correctly and evenly, otherwise the fish you’ve stocked might be very uncomfortable if they are tropical fish (and even worse, they could potentially die if their living conditions are not ideal). We would recommend a heater between 250 watts and 300 watts. If you need advice for a heater for a 75 gallon aquarium then here are some recommendations:

  • Fluval E 300 – we think Fluval make great heaters and filters, and this is a good choice for a 75 gal tank
  • EHEIM Jager – EHEIM are a great and trusted brand
  • Aqueon submersible – this is a well-designed and reliable heater
  • Marineland Precision – heating an aquarium can be very important for certain types of fish, and the Marineland Precision heater is great at ensuring every inch of your tank is heated evenly

Lighting/hood

If you want to evenly light every section of your aquarium, then you’ll likely need to buy some extra lighting for your tank. There will be LED lighting included in many hoods of aquariums, but don’t rely on that alone to properly light the entire area. Here are a few of our top choices for lighting:

  • Finnex planted plus – This is a pretty bright light and would be great for tropical fish as well as a planted tank
  • Aqueon Optibright – this is an LED light fixture and is a popular choice
  • Aqueon Modular LED – this is not as bright as the first 2 recommendations but it is much more energy efficient so is a good choice if you are concious of this

Stand

Many of the aquariums we recommend below include a stand, however if you’re planning to buy a stand separate from your 75 gallon fish tank then you absolutely must ensure that it will withstand the weight of your tank once it is full of water. Stainless steel or hardwood will be best for strength. We typically recommend that you look for the following with your stand:

  • Storage – a stand/cabinet combo is the ideal solution for a 75 gallon aquarium as it will provide room to store all of the important equipment you’ll need to maintain the tank. It will also provide space for fish food and any other accessories you have for your fish, so it’s very useful
  • Moisture-resistant paint – this one is pretty self-explanatory, but if you’re wanting to keep your stand looking good then you might like the look of a painted stand – that’s fine, but make sure the paint is moisture-resistant.
  • Solid top – as we mentioned above, when your tank is full of water it could be pretty heavy. So having a solid top will help to keep the aquarium sturdy and give you peace of mind that it won’t collapse.

Stocking/setup ideas (ideal fish for a 75 gallon aquarium)

You can choose from either coldwater, tropical or marine fish for your tank. First you need to decide on what type of fish you’d like to keep. Cold water fish can be pretty simple to look after – goldfish are the most popular variety of cold water fish.

Ideal tropical fish would include Bettas and Oscars.

Marine fish would include Clownfish or Angelfish.

For the ideal setup, you’ll want to keep Bettas away from other Bettas, and pick one type of tank that you want to have – marine, tropical or cold water.

How to set up your tank

The easiest way to set up your 75 gallon aquarium would be in the following order:

  • Clean everything – the glass or acrylic, the equipment provided with your tank and the stand. All you need is a cloth and warm water for this if it’s a brand new tank – if you’ve bought your tank from someone else then use white vinegar to remove stains.
  • Prepare your substrate – clean your substrate until the water you’re using to clean it is no longer turning cloudy, then add the substrate to the bottom of the tank (about an inch in height)
  • Equipment – set up all of your equipment, but don’t turn anything on yet
  • Add your water and dechlorinator
  • Cycle the tank and check ammonia, nitrate and nitrite levels weekly
  • Once ammonia and nitrite levels are meausred at 0ppm, this means the cycle has ended and you can add your fish
  • And that’s it!
