Safety: Safety is paramount when dealing with aquatic life; thus we scrutinized each product’s design for potential leaks or malfunctions. Features like secure locking mechanisms on hoses and sturdy construction materials were key indicators of reliability. Additionally, we considered whether filters had protective measures against overheating or electrical issues.
Aesthetics: While functionality reigns supreme when choosing an external canister aquarium filter, aesthetics cannot be overlooked—especially if it will be placed prominently within view.
