Thanks for all the help. Going to do some figuring and get something going. I'll be sure and throw some pictures up. Just in case anyone is worried that some jackleg is keeping a caiman I have over 10 years experience keeping them both in private collection and zoo so as far as the caiman its self goes I have their requirements down. Just the whole building the filtration thru me off my game. Always just done weekly water changes or bought ready to go filters. Thanks again
