# How to Calculate GPH For a Water Fountain

Knowing how to calculate GPH is important to buy the right pump for your aquarium. Flow rate is the amount of water moved per unit of time. Usually, this is expressed in gallons per hour (GPH) or liters per hour (LPH). The higher the GPH, the more water it can move at one time. You should always choose a pump with a higher GPH than the maximum head height of the fountain.

If you’re setting up a new aquarium, the first step is to decide on the size of the pump you need. Ideally, you need a pump that will produce five GPH per gallon. A pump with this rating is suited for a 29-gallon tank. However, you can go down to the next step and choose a pump based on the number of fish you intend to keep.

Then, you must decide the type of pump you’ll need. Most pumps come with a specification that lets you know the flow rate per gallon. For example, a 29-gallon aquarium needs a pump with a flow rate of 145 GPH. To find out the exact size, use the GPH calculator. This will help you choose a pump that fits your needs and is suited for the aquarium.

A simple rule of thumb to calculate GPH is to divide the pond’s water volume by the size of the pump. If your pond is 500 gallons, you need a pump with a flow rate of 500 GPH. For a 29-gallon aquarium, you will need a pump with a flow rate corresponding to 145 GPH. Using the calculator can help you determine the size of the pump you need.

When calculating GPH, you should know how much water is needed to move the water in your aquarium. A pump with a flow rate of five gPH per gallon is suitable for a 29-gallon aquarium. If your pond has fish, you need to choose a pump with a flow rate of 145 GPH. A waterfall that is four feet tall will need a pump with a flow rate of three hundred GPH.

When calculating GPH, you must consider the size of your pond. A pond with a capacity of 1,000 gallons will require a pump with a flow rate of five gph. A 29-gallon aquarium needs a pump with a flow rate of 145 GPH. A 145-gph pump would be too small for it. A 750-gph pump will be sufficient for a 20-gallon aquarium.

In order to determine the size of best ponds pump, you should first determine the height of the waterfall. Then, calculate the number of gallons in one foot. If you want a waterfall that is two feet high and sixteen feet long, you should choose a pump that can handle that amount of water. If you’re trying to simulate a Niagara Falls look with your waterfall, then you’ll need a 150-gallon pump.

The GPH pump size that you should purchase depends on how big your aquarium is. A five-gallon aquarium requires a pump with a flow rate of five GPH. The same is true for a 29-gallon aquarium with a flow rate of 145GPH. To choose the right pump, you should take the size of your waterfall and the height of the weir. Using this calculator, you can also choose the right water pressure.

When choosing an aquarium pump, it is important to consider the flow rate in the system. A five-gallon aquarium requires a pump with a flow rate of 5GPH. If your waterfall is only five inches high, you should buy a 200-gallon pump. Similarly, a six-foot waterfall needs a 3,000-gallon waterfall that requires a pump with a flow rate that is twice that much.

The GPH rate of a waterfall depends on the head pressure. It is a combination of the vertical distance from the water surface to the waterfall and the length of the tubing. For example, a three-foot waterfall with sixteen feet of tubing would have five-foot head pressure. Similarly, a two-foot waterfall would need a 3,000-gallon waterfall to require a 4,000-gallon waterfall pump.
