I've got money burning a hole in my pocket, and not sure what additions to make to my tank (i dont think i'm over stocked at present, but please tell me if i am ((see signature)). I'ts a 125 Litre tank which has quite a few real plants and i dont have any problems with water parameters (i.e. 0 ammonia, 0 nitrite, nitrate 10-20ppm, pH 7.8. Ideally i'd like something a little larger than whats already in the tank, any one got any ideas as i'm still abit of a newbie (God i hate that expression)
