Hi there, i have recently acquired a "ultrajet external filter professional uj-3337" for a mere £30 in good working order and with new media. 1st off, i need a intake guard and a outtake spreader thingy. i will also need suction cups on both pipes and a new sponge which fits inside. I cannot find parts anywhere so which filter best fits the bill? i think it looks a lot like the eheim professional (dont know which model)
