Fluval Spec V Aquarium Kit Review

Fluval Spec V Aquarium Kit, 5-Gallon

The Fluval Spec V Aquarium Kit is yet another great product from the Fluval family. I’m not sure if it’s just me, but I’ve never had any bad experiences with Fluval products. This tank is no except. It’s made of glass and is extremely sturdy. It comes with a very good 3-stage filtration system (mechanical filtration, biological filtration and chemical filtration) which is fantastic for keeping an ultra clean aquarium with minimal effort. The rounded stainless-steel corners are a nice touch as well, at least in my opinion.

Fluval Spec V Aquarium Kit Review -- Pros

As usual, I’ll start with some of the nicer features and leave off with a few things that could be improved. Since I deal mostly with betta fish, the adjustable flow filter is one of the features I like the most. The only thing that you have to keep in mind is that even at its lowest setting, your bettas might struggle a bit, especially those with larger fins. But, there is an easy solution for this. All you have to do is to insert a denser piece of sponge (new, unused, cut to proper size and rinsed) into the filtration system and it will reduce the water flow even more. It’s that easy. Again, you might not have to do that depending on the type of betta fish you have, but I’d rather warn you ahead of time. Another great feature is that the pump and filter are housed in a separate compartment, which makes the aquarium look neat and tidy. Who wants to see cables dangling around anyways? Not me. As far as cleaning is concerned, it’s a breeze. The lid and light are easy to remove and put back on, so cleaning will take no time at all.

Fluval Spec V Aquarium Kit Review -- Cons

Although this one comes close, no aquarium is perfect. The first thing that I would improve on is the lid. Although it’s easy to remove and put back on, I’m not a huge fan of the material. It’s made of plastic where the rest of the aquarium is made of glass. That would never stop me from buying it of course, but it would be nice if it was the same material all around. The 2nd thing (again, not a show stopper, just a little pet peeve of mine) is the lack of a heater. They are extremely cheap to buy (and a must for betta fish -- refer to my post on The Importance of a Betta Fish Heater) so I would highly recommend that you buy one to go along with this tank. Just keep in mind that the side compartment doesn’t have much room in it, so you will have to install it on the back of the aquarium.

  1. Great starter kit for bettas. Right now I prefer 10G for the size of my tanks, but this was a great tank when I first started out.

  2. I love my spec and I hoping for help. I am having a hard time cleaning the area below the filter. There’s a ledge and I can not seem to get into the area very well. Any and all suggestions are appreciated Thank you, Barbara

    1. Hi Barbara – sorry for the late reply. I normally just removed the filter media and then vacuumed underneath. Other than that, I don’t recall doing anything specific. Sorry, I can’t remember a ledge and I don’t have the tank anymore to double-check. Is it the Spec V (5 gallon) that you have? If you have a picture that you can send my way, that would help jog my memory.
