Beautifully crafted from red and white acrylic, this system will be the last you will ever need to purchase. It is guaranteed for life!

Pro Clear Red Flex is the NEWEST generation of Reef Sumps. It has all of the basic necessities PLUS details that make reef-keeping easy and efficient. Designed specifically for saltwater systems.

Water enters the sock chamber directly (or from your overflow box) via the intake tubes that include a unique water diffuser/silencer. The diffuser quiets the clamour of the filter for a more enjoyable experience while it breaks up the micro-bubbles to make the filter socks more efficient.

Once in the sock chamber, it falls through the 4", 200 micron filter socks. There is a unique overflow panel where the water can escape into the sump if your socks get clogged with debris, so no spills or overflow worries.

Through the socks and into the large Skimmer section, which has plenty of room for equipment such as your protein skimmer and/or filter media to suit your needs.

The Skimmer section also includes a heater rest to keep the heater off the bottom of the tank. And it has built-in probe holders as well as fasteners that hold your probes, wires and dosing lines organized and out of the way but within easy reach.

Water enters the Refugium chamber after the Skimmer area.

As the water exits the Refugium chamber into the Pump chamber the water level can be adjusted 6 to 9 inches via the adjustable flow gate, depending on your specific needs. If you want more water to reman in the Refugium, adjust the gate high. If you want less, adust the gate down.

As it flows into the Pump chamber it travels through another filter sponge for a last filtering before returning to the tank. This also helps to reduce the bubbles before the water is returned. The sponge can be replaced with another type of media if you desire.

In the larger sumps, the Return chamber is large enough for the pump as well as other equipment such as a bio-reactor.

Kit includes flexible hoses, 4 inch Micron bags and the foam block sponge that sits in the Refugium exit gate.

This sumps features a modern red and white acrylic design.
