What Should You Focus On Before An Upgrade?

The above five pumps are the best option for a Fluval Spec V pump upgrade. This is a buying guide to help you understand the pump you need. 

You already know all the aspects of the pumps on our list but it might be difficult for you to select only one from five. Therefore continue reading this-

Gallons Per Hour (GPH)

Gallons per hour, or GPH, is the unit of measurement for water pumps. Pumps are generally rated at a specific GPH rate. 

Remember that this is most possibly the pump’s maximum flow rate, but not in a real-world situation. When the pump is not connected to anything, the maximum flow rate is the amount of water it can move. 

Determine Your Ideal Flow Rate

The typical guideline among hobbyists for reef aquariums is a turnover/flow rate of 5 to 10 times the tank volume each hour.

A return pump for a 50-gallon tank, for example, would have a flow rate of 250-500 GPH at the point of returning to the display tank.

However, some hobbyists who use modern filtering techniques prefer to run a little slower, in the 2 to 4 times total tank rotation per hour range, which is just ok. This will extend the dwell time in your sump and make it operate a little quieter in most circumstances.

Simply use your tank’s total water capacity to figure how many times per hour the pump can cycle your complete water volume through the filtration system.

When calculating the appropriate flow, keep your tank’s drain capacity in mind. A maximum flow rate or range is frequently specified for overflow boxes or reef-ready tanks. 

Your predicted flow rate based on water volume must not exceed the maximum flow rate specified by the manufacturer of the tank or overflow.

If you pump too quickly, the overflow will be unable to drain the water quickly enough and will overflow the display tank.

This is a fairly unusual thing if you never pump more than 10 times your entire tank volume each hour.

Size of Pump

The size of the pump is very essential. First, you must know the appropriate pump size to upgrade your Fluval spec v.

All the above pump diameter is mentioned. You can now select the right size very easily.

The idea is to select a pump that is powerful enough to deliver the appropriate flow rate you estimated previously at the specified head pressure created by your plumbing. 

Moreover, in the preceding example, the water rises approximately 4 feet vertically, 4 feet horizontally, and then flows through two 90° elbows. That works out to about 6.4 feet of head pressure.


Question: The Fluval Spec V holds how many gallons?

Answer: The Fluval Spec V Aquarium Kit in Black comes with a 5-gallon tank, ideal for building a compact but attractive desktop fish tank.
