I am in the process of setting up my shark tank. I have been doing research as far as the maintenance and care of sharks. Questions I have is someone suggested a sand filter and a bead filter due to the waste these animals make. I am looking for anyone who has information on sharks. Who currently own sharks or have owned sharks in the past. I have a 265 gallon long tank. I know most people suggest a rounded tank but at this time I dont have one. I will be using live rock for filtration as well as a skimmer. Some sort of nitrate reducer. If anyone has or knows anyone who could share some more information with please let me know as soon as possible. I will be setting my tank up within the next week. thank you all
