Here's a current pic of my DIY acrylic sump/refuge. A 10 gallon (left) connected to a 14 gallon via bulkheads and union valves. AquaC Urchin skimmer in first tank, water flows over polyfilter and chemi-pure into refugium with LR and caulerpa of second tank, lit by a 13 watt PC, then returned to tank via Mag 9.5. Using this set-up for over a year.
