Is It True That Aiptasia Can Assist With Filtration?

I assume that this question arose when an aquarist discovered [tag-self]Aiptasia[/tag-self] in his/her aquarium and was hesitant in destroying them, or an article or comment had been read. I have no hesitation in attacking them, as left to their own devices they can spread alarmingly, like rampant aquatic weeds. First

Can You Have A Refugium In The Display Aquarium?

A [tag-self]refugium[/tag-self] is, as the name implies, a refuge where many tiny life forms can escape the hungry attentions of fish. The refugium is often a DSB ([tag-self]deep sand bed[/tag-self]) with macro algae planted. This way it serves two purposes – as said, it is a refuge and it also

Cryptic Zones Can Be As Interesting As The Display Aquarium

Cryptic zones really interest me. Of course everything in relation to this wonderful hobby is of interest to me but there is something about life growing in complete darkness which I find exceptionally fascinating. A cryptic zone is effectively a place in the aquarium or another aquarium connected to the

Live Rock Rubble – What’s That Then?

Live rock as we know is excellent at filtration within the aquarium as well as looking very natural.

Live rock rubble is a term which is heard of again and again and quite often people don’t really understand what it is and what it can be used for.

So what is it?

In the large containers either at the LFS or at the distributors where the live rock is cured prior to being made available for sale there are loads and loads of bits of live rock at the bottom of the containers.

This comes from bits of rock either becoming loosed and falling off, being knocked off during cleaning or some other method but over time there is quite a lot of rubble at the bottom of the container.

What Is A Sulphur Denitrator

Considering the maintenance of high quality seawater there are certain items we do not want to see at all, or at least wish to minimise them.

One parameter that often rears its head is nitrate. In the fish only aquarium nitrate can be allowed to rise a little, though personally I believe efforts should be made to keep it at the same level as a reef aquarium (the fish live on the wild reefs after all). The reef aquarium should ideally have no measurable nitrate, and the maximum guideline limit is 10 parts per million (ppm). This is because the reef system contains livestock that are more susceptible to trouble with high nitrate levels. Nitrate is also a nutrient for nuisance algae.

Deep Sand Bed Construction

The construction of a deep sand bed (DSB) is very simple and straightforward with only a few requirements.

Many marine aquarists undertake this job as they wish to maintain high water quality and at the same time have additional interest in the aquarium, which takes the form of the tiny, and sometimes not so tiny, life forms which hopefully will make the DSB their home.

Dr Ron Shimek is a very well known aquarist who undertakes research. Following is a link which provides all the information needed – sand type, depth etc – in the making of a DSB. In addition, some of the life forms that may inhabit the sand are given. It is very well worth a visit if a DSB is being considered.

Selecting Your Aquarium Live Rock

As we know live rock is an extremely effective filtration media to use within the saltwater aquarium. Not only does it provide filtration it also makes the aquarium look more natural.

With so many different types of live rock available however which one should you choose and how much do you need.

When setting up your aquarium you should have an idea as to what you want to keep and also what you hope it to look like. During the planning stage you should have looked into the following as well as numerous other aspects :

Feeding a Deep Sand Bed

In the salt water aquarium a deep sand bed (DSB) is a very positive addition to the system. In addition to its filtration capabilities, it is interesting in its own right.

Why so interesting? This is because, if the DSB is functioning properly, it will have a population of tiny life forms that have made it their home. In fact, a population of these creatures is important as this assists the DSB to function correctly.

The Aquarium Refugium

A refugium (or a fuge as they are commonly known) is a small aquarium which either sits next to, hangs upon, is below the aquarium or is above the existing aquarium. A refugium is normally a mixture of a deep sand bed or a mud bed combined with macro algae, however a refugium can also easily be made using a shallow sand bed and macro algae. If a substrate is provided that the macro algae can grow in then a refugium can be made.

A refugium is similar to that of the sea grass beds which are used in nature albeit on a smaller scale.

Using Mangroves As A Filtration Method

Using mangroves as a type of filtration in a salt water system was started by Julian Sprung several years ago. He planted a mangrove into one of his aquariums just to see what would happen and to his surprise it actually started to grow and flourish. An article was produced by Julian Sprung detailing the benefits of utilising mangroves in an aquarium and many aquarists started to utilise mangroves as an additional form of nutrient export.

Mangroves can be grown in various areas of the marine aquarium system. They can be grown in the sump, the refugium, the mud bed, a separate designated aquarium or even in the display aquarium if you so wish.
