Murray Hallam's Aquaponics Secrets DVD - Introducing Fingerlings

[jogtrott001]

Hi Hallam! Do you offer some on-farm trainings as well?

Hi

I am looking for people interested in Aquaponics in New Zealand. Send me a private message please if you are interested, especially in Auckland. Spammers don't waste your time with me please, I am not worth it.

awesome videooo

does it matter what kind of fish you would use in a tank??

[flashtoons]

No not really. You could use Goldfish to provide the nutrient. For eating fish like Tilapia or Trout you must read up on their requirements and provide adequate aeration and feed accordingly.

Hi,

I plan to deploy Aquaponics on my indoor fish farm as a means to filter out ammonia from the fish water. I deploy big fish tanks of 40 m3 of water each. I need to calculate the optimum plant population as well as hydroton quantity to achieve perfect filtering of this water quantity. Is there a proven analogy (i.e., plant population and/or hydroton quantity to fish water quantity) that ensures a well-balanced nitrogen cycle? Your assistance would be invaluable.

@gaggelou Hi Gag, as you know you need to nitrify then de-nitrify for your fish, this also needs to happen for the plants to be able to use the nutrients, so you will still need a bio filter before the plants, then the amount of nutrients is never enough for the plants. If you have enough for the plants the fish will suffer. Best method is to water the plants with the fish waste, but do not return this water to the fish. These systems are sold by amatures that cant grow fish or plants.

@SustainableSolution1 The gravel is inoculated with the proper bacteria to function as a living bio-reactor in the S&S system. Do I misunderstand, or are you saying that the organic solids must be filtered out of the water to the grow beds? If this is the case however, then what a waste of longer term organic nutrient, as the porosity of the growing media, be it hydroton or gravel is sufficient to filter solids- if you're raising tilapia. I realize other species have more stringent requirements

[SustainableSolution1]

@clflyguy Yes I have seen tilapia in sewerage ponds. But this is about nitrification and denitrification, not about bio-solids, what I said was plants and fish need de-nitrification, this does not happen in this setup. As for inoculated......Nitrasomonas and nitrabacter are the two working bacterias in bio filtration, inoculation wont work unless the environment is there to sustain these bacteria. Like I said wont work.

[ParadiseSurplus]

@gaggelou the nitrogen cycle is determined by two important species of nitrogen fixing bacteria which are naturally occuring in air and water. they are nitrosomonas and nitrobacter. they populate the rock medium and convert the ammonia into nitrites and nitrates, respectively. it takes roughly 3 weeks to gain a modest population and if conditions are good, they will continue to explode in numbers.

This is interesting
