STEP 3: GET THE NECESSARY EQUIPMENT
Apart from the tank and the tank stand, there is a whole list of necessary equipment to be fitting in and out of the aquarium.
The heater comes in various styles. Here I am enlisting 3 most important apparatus to buy for the smooth functioning of the aquarium.
Choose a heater based on the net amount of water available in the aquarium and not the water amount itself. It should be between 3 to 5 watts per gallon of water.
HEATER
A 90-gallon aquarium need a heater with power between 270 watts and 450 watts. Most of the models are made with 50 watts increments, therefore, your choice could vary anywhere in between 300 to 500 watts.
The best way to balance is to use 2 heaters that would sum up the upper limit. In this case, 2 250-watt heaters would be an ideal choice.
This helps create a safety valve. That means that if one heater fails, the other one would be there to compensate for the absence.
Moreover, if one gets stuck on, the other one will take a lot of time to overheat making it safe for us to find an alternative in the meantime.
There are 2 types of heaters- hang on tank and submersible. It completely depends on your personal choice or decoration styles.
You can purchase this heater for the tank-
- Adjustable heat setting 68 to 88°F, Electronic Thermostat accurate to +/- 1°

STEP 4: PREPARING THE AQUARIUM
Before adding water, make sure that you have cleaned the aquarium inside-out. Refrain from using any harsh chemicals on the inside of the tank as it could prove to be harmful for the fish.

Do not use tap water as it contains chlorine which could be harmful for the fish. Dechlorinate the tap water and then add it.
Some of the best dechlorinators are Seachem Prime, Tetra AquaSafe Plus, Natural Rapport. Do not forget to cycle the tank at regular intervals for necessary bacteria formation which provides nutrients to the fish.
