The pre filter attaches to the intake tube. Normally you have 2 pieces to the input the one that is connected into the impeller and then the second part is the intake. Sometimes fish and shrimps can get sucked through the intake! I lost about 6-10 shrimps and 3 rasboras. The pre filter is like a sponge filter its just that the tube is meant to fit on a filter.Is the pre filter before it goes to the hob?
