What is the best filter for my fish tank / aquarium?
General observation about Stingray filters – they are cr@p and I bet you haven’t sourced replacement filter medium. If you can find somewhere that sells it, don’t be surprised to find it’s about three thirds of the price of a new filter – my math is fine :o) The best filter and the cheapest to run, which is a major consideration is probably a Junior Box Filter on the end of an air pump. http://www.pet-points.com/product_info.p… The dirt is at the bottom of the tank and the Stingray is at the top. Do you want a cross current in a narrow, tall tank? Synthetic wool and loose carbon are cheap and available from any pet shop. If you go with the Stingray, you will find it doesn’t take much to block it and it is high maintenance compared with any other filter you put it against.
