HOW TO SET UP?

75 gallon is a great size for both beginners and experienced aquarists. Today I will teach you how to set it up, following the step-by-step method.

STEP 1: Clean the fish tank

If your tank is new, use a cloth to remove all the dust. Or if it is a used one, wipe it down with white vinegar and hot water.

STEP 2: Choose the right substrate

There are many types of substrate in the market and all of them are composed of different chemical compounds.

With so many choices available, it might get confusing to pick the appropriate one for your tank.

So I have done some intense research and picked up the best ones for your 75 gallon planted aquarium.


Seachem Flourite Black Clay Gravel - Stable Porous Natural Planted Aquarium Substrate 15.4 lbs
  • GRAVEL: Seachem Flourite Black is a specially fracted stable porous clay gravel for the natural planted aquarium. Its appearance is best suited to planted aquaria, but may be used in any freshwater aquarium environment.
  • AQUARIUM BED: Gravel modifiers such as laterite are not necessary when using Seachem Flourite Black as this product is most effective when used alone as an integral substrate bed, but it may be mixed with other gravels.
  • SET-UP: When adding water to the aquarium, fill slowly to avoid disturbing Flourite Black substrate bed. Place a bowl in the aquarium and add water directly to the bowl, allowing water to overflow softly on to the gravel bed. Initial cloudiness is normal, but to remove this simply use mechanical filtration
  • COMPATIBLE: Flourite Black substrates will work fine with an under gravel filter and will not soften or decompose to an unsuitable state within your tank.Flourite substrates will work fine with an UGF
  • SAFETY: Seachem Flourite Black is not chemically coated or treated, thus does not alter the pH of the water. Flourite Black is beneficial for the life of the aquarium and need not be replaced.

These are my best picks in substrate.

Besides fulfilling the aesthetics purpose, some animals actually require substrate in order to live their normal lives.

It is a great source of nutrients and necessary for the growth of plants and maintaining water quality.

Just keep in mind to rinse it before placing in the water, otherwise it will make the water cloudy. Keep rinsing it until the water turns clear.

STEP 3: Decide the location

Now you have to pick the right location for placing the tank, because once you have filled it with water, it will get heavy which will make it impossible to move.

STEP 4: Cycling the tank

Make sure to cycle the tank before you add fish to it so as to allow a bacterial population to grow which may take up to 6 weeks. The tank will cycle on its own, you just have to get a water testing kit to check if it has finished.

STEP 5: Choosing the fish

75 gallon aquariums support all kinds of setups, so you have a lot to choose from. Here are some fish ideas that you can pick from for stocking your aquarium:

TYPES OF FISH THAT YOU CAN KEEP

In a 75 gallon aquarium you can put a lot of small fish but avoid putting large number of the big ones. Here are some ideas to follow when stocking a 75 gallon aquarium.

TROPICAL FISH

  • Zebra Danio, Marble Hatchet, Silver Dollars are perfect for a 75 gallon aquarium as in this size, you can keep a lot of them.
  • Oscar and Bettas are another species that are suitable for any size tank.

MARINE SPECIES

  • Clownfish and Regal Angelfish are the right pick for a 75 gallon aquarium.
  • Moorish Idol and Mandarin fish look peaceful and mesmerizing in this size.
  • Banggai Cardinal fish species are often spotted hovering around plants and anemones, since they are nocturnal. So if you are thinking of having these ones, make sure you have plenty of live plants in your aquarium.

It is always recommended to keep one shoal or some bottom dwellers or centerpiece, in a 75 gallon aquarium.

A stocking examples could be:

  • 6 Rummynose Tetras
  • 5 Kuhli Loaches
  • 1 Male Dwarf Gourami
  • 2 Female Dwarf Gouramis

Compatible livestock includes:

  • Zebra Danio (in a group of 6)
  • Dwarf Neon Rainbowfish (in groups of more females)
  • Rummynose Tetra are mid-bottom dwellers (in groups of 5-6 or more)
  • Kuhli Loach are bottom dwellers (in groups of 4-5)
  • Bristlenose Pleco

EQUIPMENTS

The next important step is to buy the rest of the equipment. As most of the aquariums come with the kits, you don’t need to buy them separately.

However, with the other ones, you have to purchase the following:

  • Aquarium Tank
  • Aquarium Stand
  • Heater
  • Hood or Canopy
  • Filter
  • Lights
  • Air Pump
  • Fish Net
  • Fish Food
  • Gravel Cleaner
  • Decoration Items

75 GALLON FISH TANK

75 gallon aquariums are available in various shapes and sizes. You just have to pick the one that enhances the beauty of your place.

The shape of fish tank you are going to purchase is also influenced by the type of fish you want to have and the type of environment you want to create. So decide in advance.

AQUARIUM STAND

Some 75 gallon aquariums do not come in kits, so you have to purchase the stand separately. In this situation it might get hard to decide on the right size that you should go for. You have to keep a lot of things in mind, from the size of the tank, to its shape.

So I have made that decision easier for you by shortlisting the best ones for 75 gallon tanks.

If you want to create a stand of your own, you can watch a DIY video on our website.

HEATER FOR 75 GALLON TANK

HOOD OR CANOPY FOR 75 GALLON TANK

Hood or canopy is another important item, especially for the tanks that have jumpy-fish in them. With jumpy species there is risk of them falling out of the tank and dying eventually.
