Aquarium Supplies Guide

Posted by on Jan 26 2018

At CD Aquatics, we like to ensure that all of our customers are happy and well-informed before or after a purchase. For this reason, we have compiled several information guides to help you out. Here we have our aquarium supplies guide, where we have listed for you all of the available aquarium supplies and aquarium equipment that we have on offer. We have tried to explain what each aquarium accessory is and why it will be of use to you and your marine fish.

Of course, we have a lot more available than what is listed below, but we feel that these things are the most confusing to potential customers and so we have tried to clear things up for you!


As the name suggests, the undergravel aquarium filters go underneath the gravel and are powered by an Air Pump or a Power Head that draws the water down through the gravel and out through an uplift which is fitted to the under-gravel base plate filter. These are perfect for a more discreet filtration option.

Internal Aquarium Filters

These are fitted inside the aquarium on the side of the tank; two good examples of these filters are the Fluval U Range Internal Aquarium Filters and the Aqua One Internal Aquarium Filters. These filters will work wonders in keeping the aquarium clean and healthy for your fish, and are so named simply because they do this job from the inside, rather than outside the tank.

External Aquarium Filters

These are good as you can have several types of Aquarium Filter Media in them and get a good return flow of water because of the pump. These are fitted externally, under the aquarium, so they are still out of sight. Two good types of external filters are the Fluval External Aquarium Filters range and the Aqua One External Aquarium Filters range.

Power Heads

Power Heads are used for a bigger movement of water or to operate an under-gravel filter. When used on their own, Power Heads can create a good movement of water ideal for the marine tank. Two good types are the Aqua One Power Heads and the Hydor Power Heads ranges.

Aquarium Skimmers

Fitted only to marine tanks, skimmers will take out any proteins and waste produced by the fish, which is collected into a cup that can then be easily disposed of. There are several on the market; we recommend the V2 External Protein Skimmers and the Red Sea Prizm External Deluxe Skimmers.

UV Sterilisers

UV Sterilisers like the Vectron UV Steriliser range will help to cut down on the green water. They will also help to sterilise the water and kill parasites. They all have a maximum flow rate, so check your pump for this, and don’t make the mistake of buying the wrong size UV steriliser for the flow of the pump you are using.

Automatic Fish Feeder

The Hagen Pro Feed Plus Automatic Fish Feeder and the Nutramatic 2x Automatic Fish Feeder are ideal if you are going on holiday and you don’t want to put the responsibility on your neighbour to feed your fish. Most automatic fish feeders work by a battery and are very simple to use. They will distrubute food to your fish at the designated times.

Aquarium Wavemaker

The wavemaker is a device that recreates the movement of the sea in your tank. They work by fitting several power heads to it which are switched on at different times for several seconds. A good one is the Ocean Pulse Duo Wavemaker. This can make a great environment for certain kinds of aquarium fish.

Aquarium Heaters

Aquarium Heaters are used for tropical and marine aquariums and there are six different sizes of heaters to choose from. Each of these sizes are for different types of aquariums, so make sure you choose the right aquarium heater.

  • 25 watt = 18”/ 7 gallon tank
  • 50 watt = 18”/ 10 gallon
  • 100 watt = 24” / 20 gallon
  • 150 watt = 30” / 30 gallon
  • 200 watt = 36” / 40 gallon
  • 300 watt = 48” / 60 gallon

Aquarium Air Pumps

Exemplified by products such as, the Tetra Tetratec Aquarium Air Pump and the Airvolution Aquarium Air Pump, air pumps are used to increase the amount of air and oxygen content in the aquarium, which is good for the water quality and for the health of your fish. They can also be used to operate ornaments, air stones, air curtains and undergravel filters. They can sometimes be used for some types of skimmers in marine aquariums.
