i have learned that redundant filtration works best for me. i learned this on my classroom tanks, where i had no money so i had to do a "ghetto tank" - 3 ancient crusty (20 gal HOB) on a 40 breeder in an overstocked molly tank. i had to use what i had. total DIY job, dollar store plastic scrubbies for filter media, pillow stuffing, etc.
