A refugium can be made from many things in the aquarium but for the concept of this article we shall classify a refugium as an area which contains a sand covering and macro algae being grown. This type of refugium allows for two things to be completed : 1. ARead more →

Choosing aquarium lighting primarily depends upon what you hope to keep in your aquarium. If you are keeping a fish only aquarium then you can provide effective lighting using fluorescent tubes. If you are hoping to keep a reef tank then the corals you hope to keep as well as the depth of the aquarium will determine what lighting requirements you will need.
The majority of soft corals do very well under fluorescent lighting (T5, T8 etc), however if you are serious about keeping a tank full of hard corals then probably metal halide is the best for you. LED lighting is another alternative however for this post will not be covered.
No matter what type of lighting you choose to use there is one thing which you must be using.
A reflector.Read more →
Something I have thought about for quite some time now is clouds – and should we be simulating them in our home aquariums.
The fish, corals etc which we keep in our saltwater aquariums come from the wild unless that are either captive raised or coral frags. In nature the coral reef, dependant upon the location of the coral reef is exposed to a tremendous amount of sunlight. On some days the skies are blue and the sun beats down on them all day long.Read more →
The provision of light to a reef tank is a very important aspect and is only second to that of water quality.
However providing lighting is not just about purchasing a metal halide, fluorescent tubes etc and placing them above the aquarium.
We need to think about colour.Read more →
Our everyday lives are controlled by time. We may not like it but that is how it is.
On the wild reef things are much the same. I know, reef life doesn’t have a lunch hour! What they do have is dawn, day, sunset and night.
Life on the reef is controlled by these changes in light intensity. Daylight fish prepare to disappear into their secure holes when sunset arrives. Night life prepares to emerge. At dawn it reverses.Read more →
A UV filter glass is normally used on a metal halide lighting unit. The reason for this is that it prevents any harmful rays from ‘hurting’ the corals.
However do you really need to use one?Read more →
When it comes to aquarium lighting for a reef tank there is one thing which must be noted:
‘There is no right or wrong lighting, there is no lighting which is better than others’
The most important consideration is choosing the lighting which is the most appropriate for the animals in your care.Read more →
I’ve already written about LED’s (Light Emitting Diodes) of low output (see ‘LED Lighting On The Marine Reef Aquarium’). Those low output LED’s create excellent moonlight effects. This time the subject is still LED’s but ones of high output.Read more →
There is a new LED lighting system which is said to equal the power of some metal halides. If that is the case then that lighting is going to be very interesting to marine reef aquarists. Presumably the spectrum will be suitable.
Now I’ve led everyone up the garden path – I’m not writing about high power LED lighting, but just the opposite, very low power lighting. The lighting is designed to come on just before the main lights turn out.Read more →
