Sorry for the bad picture, since I am poor and cannot afford decent microscope! But we can see, that the zooplankton is eating the smaller greenalgae, but the spirulina is too big to eat.

So why I want to contaminate it like this?

First, the econiche is now reserved: which prevents weedalgae etc.

So the point is, that we can choose the contamination that in fact: is benefit in many ways.

First, as you know aeration or other mechanism is important for mixing the culture: so that oxygen will release to atmosphere more efficient. Also CO2 can be provided through aeration.

The zooplankton, is a minidevice for mixing the culture. As you can see, they move alot: mixing the culture.

Also, they produce CO2 and use oxygen: and as they eat smaller algae, the zooplankton excrements will be nutrients also to spirulina.

The problem is to balance this miniatyre ecosystem, that the spirulina will remain dominant.

In the end, we can just collect the whole biomass as fisfeed since many fish live solely on zooplankton like Coregonus albula which is also perfect fish to aquaponics since it is small and comes ready just in couple months – and you can eat it as whole, just fry it and it is very crunchy, one traditional food here in Finland!

I hadn't heard of Coregonus albula in aquaponics. Is it easy to raise in an aquarium or would they need a large pond? My husband is an avid fish-keeper, and one day we might harness his fish-keeping skills to raise food. I would like to!

No need for big pond! As the fish is only about 10 cm.

Thats why you can eat the whole fish: brains and all, and have supernutrients.

Also, imagine how simple and lowcost the fish is to grow, when you could feed the fish just with phytoplankton and zooplankton pellet: and those fed only with compost liquid?

Here is picture of the fish roasted fish, doesnt it looke delicious? It has even better nutrients at omega and all than salmon!

(btw dont use teflon, it is fluoride-compound. you know parrots were used at mines to notice if gases are around, as they die very quick from any gas? so if you buy today a parrot, they always say you cannot anymore use teflon. but how it is, that people then breath all the time dangerous gases, coming from your teflon?)

"Teflon is a registered trademark of the Chemours company (formerly DuPont) which it uses for its range of fluoropolymers, the best known of which is polytetrafluoroethylene."

In fact in the second video with better zoom (thank you Satu Zwerver for filming it with good microscope) we see that there is very small spiral shaped bacteria in the culture, that moves very much also.
