The Plenum – A Viable Aquarium Filter

A plenum is similar in nature to that of a deep sand bed but the design and creation is somewhat different.

So I guess the question is – what is a plenum?

Well a plenum is a space which is located under the substrate which separates the substrate from the bottom of the aquarium. This space is full of both water and organic waste as the water is diffused into it. A plenum system is also sometimes referred to as the Jaubert system. It is often referred to as this because it was discovered by a man called Dr Jean Jaubert.

Should You Purchase Online?

Once the aquarist has finished setting up his/her salt water aquarium as far as equipment and getting salt water in, the next big question is livestock.

Most aquarists know what they want generally, be it a fish only or reef aquarium. Many of us have a local store that can be visited for livestock purchases. Before livestock is purchased, the store is assessed as to how good the aquarium conditions are, how knowledgeable the store man is, and of course the prices being asked.

The Deep Sand Bed – One Of The Most Effective Filtration Methods.

A deep sand bed is probably one of the most common additions to live rock filtration utilised within the marine aquarist world at the moment. The other is called a plenum which I will cover in a future post.

A lot has been discovered over the years in relation to sand beds perhaps the biggest of which is the importance of the sand particle size and the depth of the bed.

Let’s concentrate on the sand particle size first of all.

Natural Aquarium Filtration

In this post I will cover what I believe to be the most powerful form of filtration currently available to the saltwater aquarist. I agree that this aspect of filtration may not be for everyone, however by understanding what natural filtration is and how it works then you can implement the type of filtration which is best for you.

There are various types of natural based filtration available – all of which never ceases to amaze me. The diversity of organisms which is in the aquarium is huge, to me these are just as interesting as the fish and corals which we keep. There have been numerous times when I have been sat in front of the aquarium when all the lights are out with a torch (with a red bulb in it) staring into the aquarium watching all the life go about its business.

“Manta Ray” Rendezvous

Location, Christmas Island, Pacific. A lovely little coral island, shaped like a horseshoe, with a lovely blue main central lagoon. The sun going down behind the palm trees on the far side of the lagoon was something else.

In addition to gawking at the coral reefs, and when I could tear myself away from them, myself and colleagues would go water skiing. When I arrived at the island I hadn’t a clue about water skiing, but wanted to learn. This sometimes was a ‘lot of salt water down the throat’ and comical process. When learning, I was told very clearly to let go of the tow rope if I fell off. Pretty obvious really. My instinct seemed to be to hang on! The tow boat crew reckoned it was the best show yet, a largish wave and a face within it followed by a submerged skier. I soon learned.

Man made aquarium filtration

Man made aquarium filtration is a term I use when describing filtration devices which are not naturally occurring. This is equipment which is used to grow or culture the bacteria required to provide an efficient aquarium filter.

Good examples of man made filtration are but not limited to :

1 External Canister Filters
2 Internal Filters
3 Fluidised Filters.

The majority of man made filters effectively follow the same principal and the majority of them utilise both mechanical filtration and biological filtration.

The Best Reef Aquariums In The World

When I sit and view my reef aquarium sometimes my mind wanders and memories come flooding in. Christmas Island (Pacific), Eilaat (Red Sea), Bahamas, St Lucia, Barbados, Florida, Mauritius, Sri Lanka, the Maldives.

I’ve been lucky and visited the above. The coral reefs are beautiful. I’m not a qualified scuba diver, but have had a look at parts of the reefs in the areas with a mask and snorkel. So it’s a bit like looking in but not being with. But the view!

The Nitrogen Cycle

We’ve all seen salt water aquariums in books and on the internet as well as in our homes. They come in all sorts of sizes and shapes, some being enormous, then all the way down in size to a nano aquarium. Whatever size they are and whether they are fish only or reef, they rely on nature’s life support system, the nitrogen cycle.

Any aquarist needs to basically understand the nitrogen cycle. There is no requirement to become a scientist, just know what is going on. Then the dangers of stressing the aquarium will be better realized (as an example overfeeding, perhaps the main problem with fledgling aquarists?).

The aquarium filter – how does it work then

Since yesterdays post we have had a few people contact us saying that it is all well and good talking about aquarium filtration and different methods etc when there are a lot of visitors to this site who are thinking about starting a salt water aquarium and do not fully understand how an aquarium filter actually works.

So here we go, this is the first of a couple of posts to touch upon the basics of aquarium filtration (what it is, how it works, methods etc)

Marine aquarium filtration – why must you

During my hours lunch break at work I decided to pop to my local fish shop to have a look around and have a cup of coffee with the owner and have a break from the pressures of work – it’s amazing how looking at salt water aquariums can take all the stress and pressure away.

Anyway whilst I was there chatting to the owner I overheard a couple of people talking – one of them was obviously thinking about starting a reef tank and they were chatting about marine aquarium filtration.
