Aquaponics; Which Style is Best Suited to Me?

Which Style is Best Suited to Me?

1So there are the basics of aquaponics, it really can be as simple or as complicated as you like, if you want to start off small and simple take a piece of polystyrene, cut some holes in it, stick some mint cuttings or water cress cuttings through the holes, and float it on the surface of an aquarium or pond, within no time you’ll end up with a mass of floating herbs, and you’ll have cleaner water for your fish. Through lots of experimenting over the years, and through the trials of members on the online discussion forum, the flood and drain media based system, has been found to be the most reliable and the simplest method of aquaponics, especially for beginners. It can be done very simply using a wide range of different containers. The flood and drain media bed system, also requires minimal maintenance.

We are going to concentrate on the media bed style of system, you can mix different styles of system but for the moment just straight media filled beds will do. Even with just straight media beds there are a number of different ways you can run the system.

Type of Systems

These are the most commonly used type of aquaponic systems.

Media Filled Beds

1Media filled beds are the simplest form of aquaponics, they use containers filled with rock medium of expanded clay or similar. Water from a fish tank is pumped over the media filled beds, and plants grow in the rock media. This style of system can be run two different ways, with a continuous flow of water over the rocks, or by flooding and draining the grow bed, in a flood and drain or ebb and flow cycle.

Nutrient Film Technique (NFT)

1Nutrient Film Technique is a commonly used hydroponic method, but is not as common in aquaponic systems. In NFT systems, nutrient rich water is pumped down small enclosed gutters, the water flowing down the gutter is only a very thin film. Plants sit in small plastic cups allowing their roots to access the water and absorb the nutrients. NFT is only really suitable for certain types of plants, generally leafy green vegetables, larger plants will have root systems that are too big and invasive, or they become too heavy for the lightweight growing gutters

Deep Water Culture (DWC)

1Deep Water Culture, works on the idea of floating plants on top of the water allowing the roots to hang down into the water. This can be done in a number of ways. This method is one of the more commonly practiced commercial methods. DWC can be done by floating a foam raft on top of the fish tank, however a more common method is to grow the fish in a fish tank and pump the water through a filtration system, and then into long channels where floating rafts filled with plants float on the water surface and extract the nutrients.

Starting A System

If you ask 10 people how to start an aquaponic system you’ll get about 9 or perhaps 10 different answers, with each person insisting that their method is best. I advice you to use this method. The idea is that you need to get a system ‘cycled’ which means establishing your beneficial bacteria populations within the system so that they can they can convert the ammonia wastes into nitrates so the plants can use them. Anyway, there are a number of different ways you can get your system started. It’s always good if you can ‘seed’ your system from an existing system or from someone who has an aquarium or pond. Aquarium filters will be filled with the beneficial bacteria you want growing in your aquaponics system, so will pond filters or even just the pond or aquarium water. So if you can collect some of this, it will help your system to establish even quicker. If you can’t find any, or don’t know anyone you can source some bacteria from,don’t worry, they will establish themselves naturally, it will just take a little longer. You may want to get yourself a test kit so that you can follow the cycling of your system, especially when using fishless methods requiring addition of different sources of ammonia.

1A test kit which tests pH, ammonia, nitrite and nitrate is best. Keep in mind that the most important thing is to get your system up and running, it’s a good idea to leave your system running for a minimum of a day or two before introducing fish or beginning any long term plans, mainly because you need to be sure that the system is working well and there are no leaks or other potential problems. Sort out any little niggling problems you may have with the system before your fish arrive because once they are in, you don’t want to then stop your system for running repairs or changes if you can help it.

Most importantly if this is getting a little confusing for you don’t worry about it, it can be difficult to conceptualize exactly how these things work, if you follow through our simple building and installation steps you’ll be able to build yourself an organic aquaponic system in no time.

  1. I was wondering if anyone knows what happened to Dimepiece Los Angeles celebrity streetwear brand? I seem to be unable to check out on Dimepiecela site. I’ve read in Elle that they were bought out by a UK hedge fund in excess of $50m. I have just bought the Nostalgia Luggage Tag from Amazon and totally love it xox
