The Vortech pumps were each adjusted from their original ½” setting to the 3/8” setting, and two were placed in each trough to create good flow for the livestock. With the four pumps running, the surface is rippling actively and it makes it hard to see the livestock. However, I do have my little floater boxes to check on my reeflings.
The cords were ziptied to prevent the motors from falling into the water below.
The Vortech drivers were velcro’d to the side the vat, and the power supplies were hung to keep them off the floor. Everything was thought out to avoid water getting into the electrical gear. Keeping the wiring off the floor and any components under the rim, it should be pretty safe.
The sand was scooped out of the tank, filling up seven salt buckets full. With six years worth of detritus in it, it has to be rinsed clean. It will then be ready for the next tank. The sandbed was about 4” thick, but none of it was clumped and I didn’t encounter any black sulfur-smelling areas. I did pull out a lot of empty snail shells and a few coral skeletons. Some hermits were discovered, two cucumbers surfaced, and I even dug up a peanut worm. These were transferred into the vats and the refugium.
