When choosing the perfect pump for your aquarium, there are several important factors to consider. You should consider flow rate, head pressure, efficiency, horsepower, and design. Price is often a factor in purchasing a pump, but you should consider how much you will be spending over time. While a cheap pump may seem appealing, it is important to remember that the higher-efficiency models are going to cost you more up-front, but you'll save money in the long run.
You should also consider the operating time of the pump. Some pool pumps have a maximum operating time of half an hour while others can run 24 hours a day. A good rule of thumb is to use a pump that runs only thirty minutes a day to ensure proper circulation. Otherwise, your fish will struggle to get enough oxygen and algae may begin to grow.
