Which Filter Should I Choose for My Aquarium?

Emperor Power Filter Choosing the right filter for your aquarium can be an intimidating task. We’re asked this question every day, from people setting up their first aquarium and from those hobbyists who are upgrading to a larger or different type of aquarium. Most people are looking for a quick and easy answer, which they rarely get from me.  There is no one-size-fits-all in the world of aquarium filters, and anyone who is new to aquariums, and is trying to do some research, is probably overwhelmed with all the options.  We have assembled a lot of good basic information for all the major types of aquarium filters in the article archives on thatpetplace.com. These articles are meant to help and guide you through the process of choosing a filter for your set-up by breaking down how each type works and in which applications they really shine.

The follow up question that I am often asked, is what is my favorite filter?  Again, that is not an easy question to answer with so many options, but I thought I might highlight a some of those I would recommend  from a few different filter types.

If you are looking for the most bang for your buck, especially for freshwater aquariums, it is hard to beat the good old power filter.  Also known as hang-on-the-back filters, power filters are easy to use, provide proven performance, and most are inexpensive and energy efficient.  My favorite power filters are the Marineland Emperor line.  These filters have been around for many years, and have changed very little since introduction.  There are two models of Emperor Filters available for under $50, that can handle aquariums up to 80 gallons.  The Emperor filters, if properly maintained, will provide excellent mechanical, biological and chemical filtration.  The Biowheel feature of these filters is what sets them apart from simpler power filters, they maintain biological filtration at all times, something that is lost on power filters that depend on their filter cartridges, which will lose all their bacteria when filters are changed.  These filters are great for any freshwater aquarium set-up as a standalone filter, or as part of a filtration system for saltwater aquariums.

Filstar Canister FilterFor larger aquariums or aquariums that demand more powerful or customized filtration, the next step up are the canister filters.  My choice in this category is another filter that is time tested, and has been around for many years, the API Filstar XP line of filters (Formerly known under the Rena brand name) The Filstar canister filters are available in several sizes, up to the XP XL model that is rated for aquariums up to 265 gallons.  Modular filter baskets allow you to customize your filter media, so you can add extra biological media for heavily stocked tanks, chemical media for low nutrient levels, peat moss for amazon tanks, the possibilities are endless.  These filters are quiet, energy efficient, and easy to set up.

ProFlex Model 1For the more advanced aquarist, especially the reef enthusiasts, the filtration system of choice is the Wet/Dry or Sump type of filtration system.  Ultimate flexibility, and high performance, are the key features of the these filters, and they are probably the most diverse of the filtration types, in terms of form and function.  My choice here is the relatively new Aqueon ProFlex filter system, mostly because of its 3 in 1, modular design.  With the ability to be used as a traditional Wet/Dry or Refugium, or Berlin style Sump, the filter has the ability to perform many functions as your needs change. If you want to convert your freshwater system to saltwater, your fish tank to a reef tank, or anywhere in between.  The Aqueon ProFlex can be whatever you need!

I hope that this helps guide you towards the filter you are looking for,

Until next blog,

Dave

    I really like the Emperor filters, but I have to say that I think the Aquaclear just slightly more.

    With that being said, I do have the Emperor on a few of my tanks. It really just depends what is on sale at the time.

    I think the thing to take away from this, is that just don’t buy a Tetra filter. lol

After graduating from Coastal Carolina University with a BS in Marine Science in 1996, I started my professional career in 1997 as an aquarist at Ripley’s Aquarium in Myrtle Beach, SC. This was an amazing experience, in which I gained invaluable hands on training in exhibit design and construction, as well as husbandry skills for a wide range of animals. In 2000 I started working at That Fish Place as one of the staff Marine Biologists, with the responsibility of maintaining one of the largest retail fish holding systems in the world. I presently hold the position of Director of Aquatic Science, where I oversee the operation of our 35,000 gallon retail aquarium systems, and provide technical support for our mail-order and retail store customer service staff. As an aquatic product specialist, I also provide support for our purchasing and marketing departments, as well as contribute web content and analysis. As a Hobbyist I acquired my love of aquariums from my father who was keeping a large aquarium in early 70’s, and set up my first aquarium when I was 12 years old. I have now been keeping aquariums for over 35 years, and through this time have kept more aquariums and types of fish than I can remember. I set up my first Saltwater aquarium in 1992, which led me down the path I still follow today.
