i have a hozelock ecopower 4500 filter for my 1000 ltr pond and it has a 1" foam sponge layer in, is it possible/feasible/worth while adding another layer of foam to help with filtration and does it have to be sponge purchased from the fish shop or can normal household foam be used as long as it is washed out first etc.
regards as ever to all
Owner of 10 goldfish, Custard, Speedy, Spot, Natalie, Colonel, Goldy, Bulldog, Blackie and Pete and Sick Note and now five new babies that have bred in the pond,(oh and 1 plastic duck, 1 rubber duck, used to be 2 rubber ducks but the lawn mower at...
re the house stuff, is that like the padded stuff to go in cushions/chairs? (sheets of foam) if so they do a grand job but you'll be cleaning it like every day or 2 as it blocks up and it'll slow the filter down
go with aquatic stuff, u can even buy the large cheap pond foams and cut out the circles
