Review for the Fluval 106 Canister External Filter

The Fluval 106 Canister Extenal Filter is ideal for tanks of up to 25 gallons and it has a flow rate of 145 gallons/hour. This flow rate can be adjusted in case you have fish that prefer low water flow in their habitats. It comes with three filtration stages that will clean up the water. The maximum flow rate turns the water over every 4 hours.

When purchasing a filtration device for your fish tank, take into consideration your pet’s preferred environment. Some fish have no problem living in water with a high flow, but some like to be in calmer waters, and high water flow may cause them stress. While a 25 gallon water tank is not too big, it is important to have a filter that is fast and powerful to effectively clean out the water to avoid waste build-up.

The Fluval 106 Canister Filter is installed externally and works buy sucking the water in and channelling it through the filter media. Remember that this filter is an improvement of the Fluval 305 Canister Filter, and is 15% quieter than its predecessor. The Fluval 106 Canister filter has a distinctive square shape that gives it an advantage over its counterparts as it is able to handle a higher flow of water and to hold 30-50% more water.

This canister filter can be used in fresh water and salt water aquariums and is equally effective in both. It comes with an impeller that muzzles the sound so you don’t have to listen to its buzz all day. Be sure to install it below the water tank. This allows water from the fish tank to flow naturally into the canister tank for filtration. Setting it on the same level as the aquarium may cause some strain on the mortar and may significantly reduce your filter’s durability. This device comes with a 3 year warranty, which is a good length of time.

Since I was young, I have always had a thing for sea creatures. Being raised along the beach gave me the chance to interact with all kinds of reptiles, including turtles. I have always found this creature quite fascinating, and at a young age, I asked my parents to get me one as a pet. My love for turtles is what inspired me to pursue marine science when I got to college. Specializing in this field made learning so much about such reptiles. If you would like to get a pet turtle at your home, this guide will be of great help.
