Trigger Systems Crystal Sumps

The CRYSTAL series sumps are reasonably priced and have the same design and quality as our RUBY series sumps but with all clear material. The CRYS30S can be used as a berlin style sump or a refugium style sump.  Some features of the CRYS30S sump are:•Locking filter sock holder•Dual platforms•Solid top support brace to prevent bowing•Foam filter block for top platform•Protein skimmer section•Refugium sectionThe CRYS30S has 3 main sections. Water drains from the tank into section 1 through the 100 micron provided filter socks. Section 1 is typically where the protein skimmer sits. Water then flows through a slit in the first baffle into section 2.Section 2 is typically used as a refugium. If a refugium is not desired, then the protein skimmer or other equipment can be housed in section 2. The water then flows over the second baffle through 2 perforated platforms and under the third baffle into section 3. The top perforated platform holds the included foam block filter and the bottom platform is open to use for several different filtration methods (bag of carbon, bio balls, rubble rock, etc.).Section 3 is the return section where the return pump will sit, pumping water back to the display tank.CRYS30SDimensions: 30″ long x 12″ wide x 15″ highDrain/Skimmer Section: 11″ x 11.5″Center/Refugium Section: 9.5″ x 11.5″Return Pump Section: 6″ x 11.5″Total Water Volume: 21.3 gallonsSkimmer Water Level: 9.5″ fixedDrain Input Fitting: 1″ (x1)Filter Sock: 4″ (x1)CRYS36SDimensions: 36″ long x 14″ wide x 15″ highDrain/Skimmer Section: 12″ x 13.5″Center/Refugium Section: 12.25″ x 13.5″Return Pump Section: 8″ x 13.5″Total Water Volume: 30.6 gallonsSkimmer Water Level: 9.5″ fixedDrain Input Fitting: 1″ (x2)Filter Sock: 4″ (x2)CRYS18CDimensions: 18″ long x 18″ wide x 15″ highDrain/Skimmer Section: 10.875″ x 11″Front/Refugium Section: 17.5″ x 6.5″Return Pump Section: 6.4375″ x 11″Total Water Volume: 20 gallonsSkimmer Water Level: 9.5″ fixedDrain Input Fitting: 1″ (x1)Filter Sock: 4″ (x1)
