Most of the breeders in Europe are using sponge filters to filter the tanks in the racks. I personnally never change the sponges in mines and clean them 1 or 2 times a year. The turbo filters are becoming more and more popular because of they efficiency and their quietness. I use a double sponge filters in 16 tanks, single in 2 and Ugf in 1. Still have a few tanks to set up and will be using Ugf in a split level way for the tanks 40 litres and over and doubler sponge filters for smaller ones.
Here is a picture of a 30 litres tank with a double sponge filter where i added 10 berried females crs/Prl, the survival rate was 20+ shrimplets/female, had to remove the adults and set up 2 bigger tank to grow the juveniles before selling them to shops.
