Section 1 where the interchangeable plate is located allowing for either filter sock or foam block mechanical filtration. This area is covered with a lid to prevent water splashing. Water then flows out the bottom of Section 1 into Section 2.Section 2 is typically where the protein skimmer is located. Water then flows through the Trigger Symbol cutout into Section 3. Section 3 is the refugium section. The water then flows over the second baffle through 2 perforated platforms and under the third baffle into Section 3.
The top perforated platform comes with a foam block filter and the bottom one is open to use for several different filtration methods bag of carbon, bio balls, rubble rock, etc. Section 4 is the return water section back into the tank. This is where the return pump will sit. Each Emerald sump comes with two plates that can be placed into Section 1.The filter sock plate is installed when the included 100 micron filter socks are desired. The foam block plate is perforated with holes and comes with a foam sponge block filter. The foam block plate can be used when filter socks are not desired or in the case when the filter socks need to be changed or cleaned but replacements socks are not readily available but yet mechanical filtration is needed. In this case, simply remove the filter sock plate and install the perforated foam block plate and then place the included foam sponge block filter in place. Adjustable Water Level Water level in the sump is adjustable from 7 to 9.5 to accommodate for the water height requirements for different protein skimmers. Self-Adjusting Foam Block As the water level is adjusted by sliding the wall up and down, the foam block sponge filter and the perforated plate that it sits on will also move up and down automatically. This is important to maintain the correct location of the foam block sponge filter with respect to the sump water height.
