Mary Rose.......Sand filters ...

Mary Rose.......Sand filters can be a good solution however, it is better to treat the water with biological enhancement product that is organic and biodegradable. before it enters the filters.
This will have a secondary effect of keeping the sand filter clean and will initially remove fats, oils and grease and keep malodour to an absolute minimum.
