The big problem of raising and breeding pond's life is that such small creatures are subject to seasonal cycles. In winter they all die leaving on the bottom eggs that will hatch again in spring. Acquariums kept in the apartment suffer from excessive water temparature and could not ensure the "winter" period.
That's why I decided to install in my garden a small pond to observe how those small critters could survive the winter.
There are many different ways to install a pond. The 2 less expensive are:
1. Using a waterproof textile to cover a big hole in the ground
2. Using a plastic preshaped ponds
Unfortunately both solutions require a big big hole (600 l min) in the garden. Lot of work and lot of soil to be placed somewhere. Therefore I decided for a different solution. I used an industrial pallet box, designed to contain liquids. This is cheaper and do not require a big hole to be digged.
I filled it with tap water, than I left an acquarium biologic filter charged with active carbon and ionic resins for a week to ensure all dangerous substances have been removed. I also used water conditioner to be on the safe side.
AFTER ONE WEEK
After one week the pond was in place I noticed different kind of eggs on the surface. In a few days the water was full of mosquitos' larvae. Now I need to find a way to filtes out the larvae without killing at the same time the nice guests I already introduced.
AFTER 3 WEEKS
The ostracods and the daphnie I introduced after the first week are now acclimated to the new environment and swimm all over the pond.
AFTER ONE MONTH
In a sunny day, the pond is full of ostracods while daphnia and simocephalus are less visible. I also placed here the two notonecta glauca. Mosquito larva have disappeared.
