Hi

Im after some advice about my filter. In the past couple of days we noticed
that the pond water level had dropped a good few inches and just put it down
to the sunny weather weve been having. Anyway we have noticed today that the
reason for the sudden drop is that the water is overflowing from the filter
box. Is this because its too small and that we need a bigger one?

any advice would be greatfully recieved

Thanks
Cheryl
