Starting with filtration, you will need to know: Simply multiply the tank’s length x width x height / 1000. The result will equal how many litres of water your fish tank holds. Example: You have a fish tank that measure 150 centimetres in length, 55 centimetres in width, and 55 centimetres tall.

How many litres per hour should my filter be?

When deciding on a filter, the flow rate should be at the very least 3x the volume of aquarium water passing through it per hour. This is measured in litres per hour (lph). So for a 300 litre tank, there should be 900 litres passing through the filter per hour. Anywhere up to 8x the volume of water is recommended.

What is aquarium filtration capacity?

These filters are available in a full range of sizes. A good rule of thumb is to select a filter with a flow rate at least six times the volume of the tank—so for a 30-gallon tank you want a flow rate of about 200 gph (gallons per hour).

How do you calculate filter capacity?

For example:

1. Circulation Rate: 100 cubic metres per hour.
2. Filter Surface Area: 5.71 metres squared.
3. Filtration Rate: 125m3 / 5.71m2 = 21.89m3/m2/hr.
4. Width of filter: 2.7 metres (this is also the diameter)
5. Radius: 2.7m / 2 = 1.35m.
6. Radius Squared: 1.35m x 1.35m = 1.82 m2.
7. Surface Area: 1.82m x 3.14 (pi) = 5.72 m 2.

What size filter do I need for a 40 gallon tank?

As a minimum, your filter should be able to clean at least four times the size of your aquarium per hour. For example, a filter for a 40-gallon tank should have a water flow rate of at least 180 GPH (gallons per hour).

What is filter flow rate?

The filter flow rate is defined as the amount of water filtered over a given period of time, expressed in gallons per minute.

How do you calculate flow rate in a filter?

What size pump do I need for my aquarium?

A good rule of thumb to follow is that a pump should have a flow rate of 5 GPH (gallons per hour) for every gallon of water in the aquarium. For example, if you have a 29-gallon aquarium you will need a pump with a flow rate of at least 145 GPH to effectively turnover the tank.

How many fish can you have in a 30 Litre tank?

With a mature tank, good water quality and regular maintenance you could keep a community of 20 tiny nano fish in a 30 litre BiOrb, or 15 fish the size of a Zebra danio.

How do you calculate bag filter capacity?

First calculate the total cloth area of your collector by calculating the total filter area of each filter (bag diameter x 3.14 x length ÷ 144 [for number of inches in a square foot] = filter cloth area) and then multiply that figure by the total number of bags in the collector.
