If functional and flexible is your goal, the Trigger Systems Crystal sumps are made for you. The Crystal series sumps provide you with a fully functional sump, complete with a filter sock, baffles, and bubble trap. Everything you need, affordable price point, and the flexibility to customize exactly as you desire.  

Each sump is made from clear acrylic and features three chambers to hold all of your life support equipment. The locking filter sock holder securely holds 4" socks and includes a threaded PVC coupling for easy connection to your drain.  The dual-platform bubble trap baffle allows you to place filter media bag with media of your choice in between the sponges without worry of it escaping.
