I am thinking of changing my current setup to a sand bottom. Ive attached a photo of my current setup. I have a 75 Gallon with a lutino oscar, Jack Dempsey and a pleco. what are some suggestions and advice with sand bottoms with oscars. Will the sand mess up my filter, im running an eheim cannister filter. Also, what are some of the best sands that you guys have had success with or liked the best and if you have any suggestions on white or black sand let me know what you think.
