keith walters Asked:

Regarding cleaning of the filter, what has to be done and how does it work?

We Replied:

Dear Keith Thank you for your question. The blue handle on the top of the filter is pulled up and down which squeezes the sponges together cleaning them, when you do this it is best to remove the outlet pipe from the pond and put it into the bucket. Should you wish to contact us further or to place an order, please call us on 0121 355 7701. Thank you for using our online Q&A system. Kind regards Dan Everton
