step 1:
take a aquarium and clean it with a newspaper. the newspaper should not be big. all the sides of the aquarium should be transparent because if you don't do that you'r fish might die and also keep the aquarium in a clean environment.the aquarium has to have a cover made of plastic and should have a light system.
step 2 :
then bring the marine gravel and the marine salt from a near by pet shop .you have to buy a skimmer which would keep your water clean and also need a stress court with a growth stimulator which you have to put in the aquarium to save your fish from dieing. you will also need a powerful filter and the if the climate is very cold you will need a heater .
step 3:
mix the marine salt in the water which you poured in the aquarium.after mixing the marine salt ,the water will get white because you have mixed the salt .then pour 4 drops of the stress and also pour 4 drops of growth stimulator in the head of the skimmer.after pouring it start the skimmer and dont't put your and don't allow anybody to put his or her hand in the aquarium.
step 4:
do not put the fishes on that the day because water should be kept for 6 to 8 days and if you keep the fishes your fishes will die.after that take 30 to 35 litres of water in a another bucket and mix 1kg of marine salt in the water .keep the water stored because if the water of the aquarium gets evaporated because of the heat of the heater, you ready with the water.
step 5:
put the fishes after 8 days and you will need a amoenia kit which would tell you if the water has any poison for the fish .you will need a salinity machine which would tell you the salinity of the water if the water is suitable for the fishes . you have to out 4 drops of stress court and 4 drops of growth stimulator every month.your marine aquarium will get set . this is my ways how to set a marine aquarium . thank you for reading.
