DIY Aquaponics is a very interesting field and it grows more and more. Recently, a way has been discovered to increase the yield of green cultures by as much as 10 times. The new approach is being incorporated into new commercial aquaponics systems as well.
There are many advantages of DIY aquaponics over hydroponics. The main difference is the "chemical" taste, which hydroponics often have. Aquaponics do not have that, because they use organic fertilizer, produced by fish. Now let's look at some vital points, which some people miss.
1) Oxygenating the water - this is important and is key to a successful and efficient system. If you lack oxygen, anaerobic bacteria will start developing, and the fish are likely to die.
2) Light - proper lighting is vital. Placing the system outdoors is best, but if that is not possible, artificial fluorescent lighting can be provided.
There are many more 'tips and trick' to ensure that your system runs efficiently. Unfortunately, you can rarely get those secrets for free, because aquaponics is becoming more and more a business model of growing organic tomatoes, cabbage and other green leafy vegetables. The choice of fish for example, can be a determining factor in the efficiency of the system. Combining fish that eat meat, with omnivorous fish is a good strategy, because the carnivorous fish will produce much more nitride-rich fertilizer, but it will also lack some basic elements like calcium and magnesium. Choosing the soil particles is also important. There are many types of pellets which can be effective in this system. Unfortunately, some of the cheaper ones contain additives, which are not suitable for the fish, and further filtration must be done.
If you know the secrets to a successful aquaponics system, you won't have to deal with the headaches of nutrient deficiency, oxygen deficiency, bacteria, lack of equalization of the cycle, and much more minor problems, which compound over time and lead to a failure of the system. The good thing about aquaponics is that it is easily scalable - you can build it any size you want, without compromising efficiency. Many people choose to build a small and simple indoor system in order to satisfy their interest in aquaponics, and then decide it is time for something bigger and useful. It's up to you to decide what size of a system you want. If done correctly, DIY aquaponics are fun and productive!
