Coral Propagation

There are many reasons why you should your frag corals: to help save the world's reefs, produce healthier specimens and for sale or trade, to name a few. Here are the tools you will need.

Featured Tank

Occasionally we'll highlight one lucky customer's tank as our "Featured Tank." In addition to bragging rights, we hook up the tank's owner with free goodies. Check out their specs and see what they're doing right.

Finding Nemo

Disney's Finding Nemo inspires people of all ages to get started in the aquarium hobby. Learning how to take care of the animals in the film is a great way to determine if owning a saltwater tank is right for your family.

Curing Live Rock

Live rock is an excellent biological filter. Curing live rock before adding livestock to a new aquarium allows ammonia and nitrates to cycle while preserving the beneficial organisms you want in your reef.

Livestock Acclimation

Acclimation reduces the stress animals face after relocation. We'll teach you everything you need to know to properly acclimate your fish, corals and invertebrates to ensure they live a long, healthy life.

Charts & Diagrams
