Assuming the aquarium is a rectangular prism, multiply the three dimensions to get 2.17 cubic feet. To convert this to liters, remember that a liter is equivalent to one cubic decimeter. There are 2.54 centimeters per inch, 10 centimeters per decimeter, and 12 inches per foot. So...2.54cm/in * 12in/ft / (10cm/dm) = 3.048dm/ft2.17 ft3 * (3.048dm/ft)3 = 61.447557105dm ~= 61.4dm ~= 61.4 liters
Volume: 30*15*12 = 5,400 cubic feet
water level in aquarium not high enough or if it is, add some water to the filter equipment and sound will stop : )
To calculate the volume of an aquarium measuring 4 feet long, 2 feet wide, and 1.5 feet high, you multiply the dimensions: 4 x 2 x 1.5 = 12 cubic feet. Since there are 7.48 gallons in a cubic foot, you multiply 12 by 7.48, resulting in approximately 89.76 gallons. Therefore, the aquarium holds about 90 gallons.
192.5 liters or 50.85 gallons
Six million cubic feet (168,000 cubic meters) of water flow over the crest every minute during high flow.
The ammonia level may still be high after a water change because the beneficial bacteria in the aquarium may not have had enough time to establish and break down the ammonia. It is also possible that the tank is overstocked or overfed, leading to excess ammonia production. Regular water testing and maintenance can help address high ammonia levels in the aquarium.
A cubic metre, a tonne, 1000 litres
High nitrite levels in an aquarium can be caused by overfeeding, overstocking, inadequate filtration, or lack of water changes. To lower nitrites, try reducing feeding, adding more plants or beneficial bacteria, and performing regular water changes.
High nitrate usually means the filter is doing a great job but you are not doing enough water changes. My advice is to make sure you do at least a 50% water change every week.
The height of 400 gallons of water would depend on the shape of the container. 400 US gallons has a volume of about 206,000 cubic inches, so if the inside of the container was about 59 inches square, it would also be about 59 inches high.
23*27*2 cubic feet = 1242 cubic feet.
