Without it, the water would quickly become cloudy and unsafe for my aquatic pets.

My Buying Guides on Hang On Filter Aquarium
When I first started setting up my aquarium, I quickly realized how important a good filtration system is. After some research and hands-on experience, I found that a hang-on-back (HOB) filter is one of the most convenient and effective options for many aquarium enthusiasts like myself. If you’re considering buying a hang-on filter for your aquarium, here’s my guide to help you make an informed decision.
Why I Chose a Hang On Filter for My Aquarium
From my experience, hang-on filters are easy to install, maintain, and provide excellent mechanical, chemical, and biological filtration. They hang neatly on the back of the tank, saving space inside the aquarium and keeping the water clean and clear. I found that they are also generally quieter than some other filter types, which is great if you want a peaceful environment.
Key Features to Look for in a Hang On Filter
When I was shopping, I focused on these important features:
- Flow Rate & Tank Size Compatibility: I made sure to pick a filter with a flow rate suitable for my tank’s size. Typically, the filter should circulate the entire tank water 4-6 times per hour. For example, if you have a 30-gallon aquarium, look for a filter rated for at least 120-180 gallons per hour (GPH).
- Multi-Stage Filtration: I prefer filters that offer mechanical (removes debris), chemical (removes toxins), and biological (houses beneficial bacteria) filtration. This ensures comprehensive water cleaning.
- Ease of Maintenance: I look for filters with easily accessible filter media compartments so I can change or clean the sponges, activated carbon, or bio-media without hassle.
- Quiet Operation: Since my aquarium is in a living area, I chose a filter known for quiet performance to avoid annoying noise.
- Durability and Brand Reputation: I read reviews and chose a model from a reputable brand known for quality and reliable customer support.
Types of Filter Media I Use and Recommend
In my setup, I use a combination of:
- Mechanical Media: Foam or sponge pads to trap particles.
- Chemical Media: Activated carbon to remove odors and discoloration.
- Biological Media: Ceramic rings or bio-balls where beneficial bacteria grow to break down harmful ammonia and nitrites.
Some hang-on filters come with all these media pre-installed, which is convenient for beginners like me.
Installation Tips I Learned
Installing a hang-on filter was straightforward, but here are some tips I picked up:
- Ensure your aquarium has a rim or lip sturdy enough to support the filter’s weight.
- Prime the filter if required (some models need you to fill the intake tube before starting).
- Position the filter so the water flows evenly and creates good surface agitation for oxygen exchange.
- Regularly check for leaks or unusual noises during the first few days.
Maintenance Routine That Works for Me
To keep my hang-on filter running smoothly, I:
- Clean or replace mechanical media every 2-4 weeks.
- Replace chemical media like activated carbon monthly.
- Rinse biological media gently in tank water (never tap water) during water changes to preserve beneficial bacteria.
- Check the impeller and tubing for debris monthly.
Final Thoughts from My Experience
A hang-on filter has made a big difference in maintaining a healthy, clear aquarium for me. It’s a reliable, space-saving filtration method that balances performance and convenience. When you choose your filter, consider your aquarium size, the type of fish you keep, and your maintenance preferences. With the right hang-on filter, you’ll enjoy a cleaner tank and happier aquatic pets just like I do!
