Christopher Turner Asked:

I have the BioTec Screenmatic filter set 40000 and I am thinking of changing the Zeolite cartridges to Phosloss. It says in your description that you should change every 6 weeks, can you not just wash them with pond water? Also do you sell it by the bag or do I have to spend £37 every 6 weeks?

We Replied:

Dear Christopher Thank you for your question. This is only available in cartridges, they can't be washed out and would need replacing. 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
