http://www.aquariumproducts.com.au/catalogue_products.php?prodID=3613&catID=79I've ended up buying a pool pump, sand filter, bio booster and UV light for my pond in the end. Didn't want to cos of the sound it would generate outside my sons room but I'm just going to place it further away.
So I bought this filter last week from a friend, it's 8 months old and in excellent condition, think these go for well over R3k brand new.
Click on the link above to check the specs out, suitable for a pond up 13000lts without fish and 6500lts with fish.
I want R1250 for it
