To help in making life that little bit easier our Technical Experts have come up with a handy device to help work out what
dose to give of each King British product. Simply enter the dimensions below and away you go! When entering your aquarium/tank
dimensions please make adequate allowances for the displacement of water by gravel, rocks and equipment.
Our water volume and surface area tools are helpful tools to help you determine appropriate tank population and whether
you have the right tank for future additions to your tank.
