How to Maintain and Take Care of Your 75 Gallon Fish Tank


Every visible as well as major internal parts like filter need adequate cleaning in every few months. Nothing is as worse as dirt deposit in an aquarium. In order to ensure the fishes don’t face any troubling during the cleaning process, focus on one substrate of the tank at a time. Replicating the marine life inside an aquarium has never been a child’s play. To keep up the balance in nature inside the tank, the growth of bacteria present in water naturally cannot be disrupted at any cost.

Water Cycling

Cycling the water in the aquarium is essential for the wholesome nourishment of your delicate aquatic dearies. Cycling is the method of encouraging healthy bacterial growth in the water. It is a hygiene essential I mentioned in the section above. For the new fish lovers, growing bacteria inside the tank might sound like a knave concept. The thought behind doing this is simple. The good bacteria transform ammonia from food and fish faeces to nitrate and nitrite. This is how the nitrogen cycle of the water is carried on. Replace the water regularly to prevent the water from toxication.

Water Testing

Testing the ammonia level and pH level of the water is a step you can’t miss. For salt water tanks, keeping track of the salinity level along with these to ensure everything is properly balanced. Aquarium water test kits are easily available.


As soon you find the right 75 gallon fish tank for your little pals, don’t forget to purchase a suitable aquarium filter as well. A gallon per hour or GPH rating is a must-have feature for the filter of a plus size tank. Aquarium aficionados suggest a minimum 300 GPH filtration system for 75 gallon fish tanks. As far as I’m concerned, I always count on a little higher than the recommended digit for maximum safety. A combination of biological and mechanical filtration is ideal for fresh water fish tanks. Chemical filtration is also an alternative but be very cautious about the amount of chemical you’re going to put in the tank, for obvious reasons.

Proper Heating System

Freshwater fishes require a warm temperature to thrive and flourish. Constantly fluctuating temperature has a negative effect on the health of the fishes. Always keep a thermometer handy to check the temperature of the water and adjust it whenever required. For a jumbo fish tank, having a backup heating system is a smart move as you’re likely to house either a large or multiple fishes in the tank. In case, the inbuilt system fails to function, replacing it would be one hell of a hassle.


A 75+ gallon fish tank can be a gorgeous addition to your room. The background, decoration and lighting of the equipment make a huge difference on the appearance of the room. The decoration isn’t only a delight to the eye, embellishing the underwater surrounding with false castles, coral reef, leaves, tunnels originate a playful environment for the fishes who love to swim around, roll and jive around all day. Watching them playing in their natural environment under moonlight sitting in a dark room is a soul-steering sight.

Find the Right Location

For a large scale tank that weighs no less than 500 pounds, choosing a permanent location is vital. Taking it from one place to another, like you do with your fish bowl or small tank is simply not even an option here. So, when you’re planning about purchasing a 75 gallon fish tank, make sure you’ve the room for it. Getting a suitable cabinet should be second on your priority list. To hold a bulky structure like this, you need to have an industry-level cabinet for it. It depends on the fish owner whether he or she wants to replicate a salt water or fresh water environment for the creatures in the tank. I’d personally recommend amateur fish owners to go with fresh water as maintaining a salt water environment requires some basic knowledge about the right salinity level.

Words of Caution

No seasoned hobbyist would make the mistake of putting the aquarium under direct sunlight of in a cold area ever. Extreme temperature is not favourable for most fishes. Exposure to sunlight for a long time encourages algae growth in the water. To prevent the tank from damage or breaking, keep it in a secure, less traveled place of the house. Don’t place it on a very high place from where you can’t see the bottom of the tank. Proper access to the equipment will make maintenance of the fishes less complicated.

Winding up the 75 Gallon Fish Tank Saga

Buying a huge fish tank is a worthwhile investment only when you know what to exactly do with it. If you’re thinking to get one despite a limited space in the house, it’s better to go for a smaller model. Maintaining an ultra-heavy tank is certainly going to seem tough for the inexperienced customers. Features like sliding doors, clear glass cover add to the ease of maneuvering. Nothing can be as soul-pleasing as decorating an expansive landscape with colorful aquatics for people who share a true passion for aquariums. Time to time maintenance will help you extend the shelf-life of the tank and will also keep the animals healthy and cheerful.
