Bulk Heads and Plumbing supplies are essential when setting up a saltwater aquarium with a sump for filtration. Bulk Heads are used to seal between the glass and plumbing on glass or acrylic aquariums.
Uniseals are used to seal between plumbing PVC pipe and acrylic or glass on your aquarium. Uniseals are similar to bulkheads except they use compression for a water tight fit.
Loc-Line Modular Hose is great for using on the return line from your sump as the last part into your aquarium. Using the ball socket style LocLine allows you to flex, adapt, and change the output direction and area.
Strainers are used to protect your pipes from getting clogged by snails or other items.
