Fluval C2 Power Filter Review

Finding a good filtration unit for an aquarium might seem like an easy task, but it can be tricky. There are so many different filters out there, all with different features, capabilities, pros, and cons, that coming to a decision can be a tricky process.


However, every now and then, we personally find aquarium filters that are fairly decent, in which case we like reviewing them. Today we are here doing a detailed Fluval C2 Power Filter review (you can also check the current price here). While this particular filter does have a couple of minor drawbacks, overall it is a pretty decent option to keep in mind.

Features


The Fluval C2 Filter has quite a few neat little features that are worth talking about. You might not like them all, but some people can definitely find a use for them.

Filtration Capacity

The first thing that you probably want to know about here is what the filtration capacity of this particular aquarium filter is. Well, this thing is rated to be used for aquariums up to 30 gallons. While this is not all that much filtration capacity in terms of aquarium size, this thing should do fairly well for anything at or under 30 gallons, even for fairly heavily stocked tanks.

Now, the Fluval C2 Filter can process around 120 gallons of water per hour. While the filter itself is not that big, being able to handle up to 4 times the total amount of a 30 gallon aquarium per hour is quite impressive.

Filtering the water 4 times per hour is considered to be on the better end of the spectrum when it comes to aquarium filters. On a side note, while this thing doe have lots of power, it is a little but loud. The motor doesn’t exactly run too quiet, which is something that some people might not like very much.

5 Stage Filtration

Unlike many other aquarium filters out there which are 3 stage filters, this one is actually a 5 stage filtration unit. Now, it does engage in all 3 major forms of filtration including mechanical, biological, and chemical filtration.

First off, the first 2 stages of filtration which the C2 Filter features are both mechanical types of filtration for debris removal. One benefit here is that this filter comes with a cleaning indicator which lets you know when the poly-foam pad needs to be cleaned or changed. The third stage consists of a carbon filter for the removal of chemicals, odors, and toxins.

The fourth and fifth stage of filtration here are both biological in nature for the removal of ammonia, nitrites, and nitrates. All in all, the filtration power here is quite good. Now, one thing that needs to be said here is each type of media here has a different shelf life.

This means that you will be replacing one kind of media or another every month or so. While accessing the media on the interior of the C2 Filter is not hard by any means, the fact that it needs to be changed quite often is a bit of a drawback.

Heating

An aspect that we personally like about the Fluval C2 Filter is that it features an efficient heat distribution method. Now, as you might know, the motors from filtration units produce a fair amount of heat. This can be a bad thing if you need your water to be fairly cold, as this thing will heat up the water a bit.

However, if you need warm water for your fish, it’s not such a big deal. Anyway, this particular filtration unit uses a special heat dispersion method to ensure that not too much heat is created or let out into the water.

Yes, it still lets off some heat, but not quite as much as some other filters which do not come with this feature. Just keep in mind that this thing does produce some heat.

The Trickle Waterfall

Another feature which we personally find pretty neat here is the trickle waterfall feature. When the water is done filtering, it trickles out back into the tank via a little trickle waterfall. This can be beneficial because tanks, especially fish tanks that are heavily stocked, often have aeration and oxygenation issues.

In other words, tanks with lots of fish require higher amounts of dissolved oxygen to be in the water. The trickle function here helps to push some air into the water in order to aerate it so your fish can breathe easier.

Now, some people love the gurgling noise which this thing makes as the water splashes into the tank, but some people hate the noise. There is no denying the fact that this thing is quite noisy overall.

Hang On Back

Something that some people may like about the Fluval C2 is that it is a hang on back filtration unit. For one, this can be seen as a good thing, because instead of taking up lots of room inside of the aquarium, it simply hangs on the back of it. In other words, it leaves more prime real estate for your fish, which is definitely a good thing.

Also, this particular filter simply hangs on the back of your tank with little clips. This means that installing it and getting it ready to go is no big deal. Simply hang it on the back, secure the clips, and you are more or less good to go.

All in all, it might be a bit of a chunky filtration unit, so you do need a fair bit of clearance behind your aquarium, but overall, we personally like how it does not take up space within the tank itself.

Pros

  • Ideal for heavily stocked tank.
  • Lots of processing power.
  • Includes all 3 major types of filtration.
  • 5 stage filtration for clean water.
  • Helps to aerate the water.
  • Special heat dispersion function.
  • Cleaning indicator feature.
  • Simply to install.
  • Hangs on the back easily.

Cons

  • Often media changes required.
  • Fairly loud.
  • Produces a bit of heat.
  • Requires a fair bit of clearance behind the aquarium.

Alternatives

Just quickly, in case you have different requirements than what the Fluval C2 can provide you with, we want to mention a couple of alternatives. No, here we are not talking about different brands, but larger sizes of the same Fluval C2 Filter unit. Fluval also makes the same model, but larger. There is the C3 and the C4.

Both of these filters are pretty much the same as the C2, but with larger filtration capacities. The Fluval C3 can handle up to 153 gallons per hour and the C4 can handle a whopping 264 gallons per hour. In other words, if you have a tank that is larger than 30 gallons, you will want to check out either the Fluval C3 or the C4 as they are bigger.

You can checkout the C3 here and the C4 here.

Verdict

In terms of the Fluval C2 Filter, we think that it is a decent filter option (you can see the current price and more information on Amazon here). While it does have some drawbacks like often media changes, noise, and clearance issues, overall it seems to be a good unit to keep in mind. This thing is built to keep water clean and it seems to perform that task quite well.
