Hi, Frank Indiviglio here. I’m a herpetologist, zoologist, and book author, recently retired from a career spent at several zoos, aquariums, and museums, including over 20 Red Eared Sliders and other semi-aquatic and aquatic turtles have just about everything one could ask for in a reptile pet – fascinating behaviors, responsiveness, breeding potential, beautiful coloration and shell patterns and with proper care, the ability to outlive scores of dogs and other “lesser beasts”. But however how much we may enjoy them (and I know folks with collections numbering 100 to 2,000+!), keeping their water clean, both for clarity and health reasons, can be a frustrating and time consuming task. Today I’ll review some useful points to consider when deciding upon a filter. Please post your own experiences, thoughts, and questions below.
