When this topic arose I wondered what to do with it. The reason I wondered is that this website is designed for beginners and ‘earlier-on’ aquarists (though I notice that experienced aquarists are now visiting, and they’re more than welcome). Lighting is a scientific and technical subject. Most things canRead more →

Our marine aquariums for the most part, whether reef or fish only, are very natural, far more so than they were even just 10 years ago. Technology has advanced a great deal as well. The lighting is designed to help the corals and also look reasonably natural, the filtration isRead more →
In years gone by aquarists lit their aquariums with tungsten lights. They probably had no idea of spectrum, probably had lots of algae growth, and I would imagine the heat output would have caused problems too. Methods advance. Nowadays there are two main lighting systems, fluorescent tubes and metal halideRead more →
The marine aquarium has two main types, the fish only (FO) and the reef. These systems have a good few things in common, one that is not common to them is the aquarium lighting. Water quality is the number one requisite in a marine aquarium, and this is closely followedRead more →
In the refugium we are attempting to grow macro algae. The reason for this is that as they grow they remove nutrients like nitrate and phosphate out of the water. In a previous post I have discussed what type of lighting should be used so that you can get optimumRead more →
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 →
