Heat and Light

The basic essentials for comfortable aquarium living  The majority of tropical fish thrive in temperatures of 760F to 800F and it is important to provide an appropriate and stable temperature for your livestock. We stock a extensive range of combined heater/thermostats as well as a number of new innovative products to help create and maintain the desired temperature.

During the Winter months it is important that your heater has sufficient capacity to maintain the temperature of your aquarium, even on the coldest of nights. As a general guide, you should allow 1 Watt per litre of water, for example, in a normal centrally heated home a 200 litre tank requires a 200W heater. If the room is other than a normal Living Room or Lounge then it may be necessary to increase this to ensure that the heater can maintain temperature during cold snaps.

It is recommended that wherever possible, two lower wattage heaters should be used rather than one higher powered unit. Whilst modern heaters are extremely reliable, they do occasionally fail, usually in the ON condition. Using two smaller heaters usually allows the fish keeper to spot the problem before the fish get "Cooked".

Whilst most fish are not overly fussy about lighting, or lack thereof, it is important not only to the overall biosphere, but also to the owner who may like to see his or her fish on occasions.

Today's technology has come a long way from the simply incandescent lamp suspended over a bare glass tank.  Modern lighting is available in a huge range of spectrum, Colour Temperature and intensities. The standard florescent tube, (T8) is slowly being superseded by the more intense T5 models, and with colours available to simulate the full range of aquacultures, from the clear mountain stream to the vast silt laden river basins or deep African rift lakes.

For the marine keeper Metal Halide discharge lamps provide intensities suitable for even the most demanding corals, and in colour temperatures as high as 20,0000K.  For many marine invertebrates this extreme light is necessary in order for the organise to produce its food by photosynthesis.
