I realized that a filter pump not only keeps the water clean but also provides essential aeration.

Types of Filter Pumps

I found that there are several types of filter pumps available, and understanding each one helped me narrow down my options. The most common types I considered were hang-on-back filters, internal filters, and canister filters. Each type has its advantages and disadvantages, so I made a list of what would work best for my aquarium setup.

This ensures efficient filtration and a healthy environment for my aquatic life.
