Floating, square breeding ring with air lifting filter.
The mesh size of the gauze on the bottom is 15my, the ring diameter is 150mm.
With these rings, there is a constant water exchange through the air lifting filter and the air outlet.
The gauze is so fine that feeding animals such as nauplii do not escape from the brine shrimp.
With these rings, rearing catfish larvae, for example, works without any problems.
Other fish offspring can also be raised very well with these rings.
