I have just taken delivery of an Eheim 2071 (Pro 3 - 250) and it only has 2 baskets, not 3 like I thoight. So which one of the medis do I not use? It come with Mech pro and Substrat pro but I'm concerned that it doesn't take biomech. What should I do, leave it out of split it with one of the other medias?
