    Do you know that feeling? That feeling when you know something bad is happening in your tank and you don’t know what to do about it? That panic deep in your gut that says “ACTION! You must do something about this NOW!” We’ve all had that feeling at least once. The fear of losing $1000 or more of fish and coral because you didn’t act on a problem fast enough is a real one.

  8. Tigger-Pods (Tigriopus californicus): addressing the cold water myth

    top frustrations is the myth that Tigriopus californicus are a "cold water species". I hear this from store owners and hobbyists ALL the time. This copepod is eurythermal. For those of you that don’t know the term, it describes an organism able to tolerate a wide range of temperatures. Tigriopus californicus is both euryhaline and eurythermal, withstanding and remaining active in salinities from 4ppt (Vittor 1971) to 102ppt (Egloff 1967) and temperatures from 4C (39.2F) (Vittor 1971) to over...

With preparation in mind, here are some tips that could be useful.
  10. Yes, Reef Aquariums inspire action.

    Lauren grew up about two hours from where I did, in what is still considered Western Maryland.

Much of that life is highlighted at the Outer Banks Aquarium in Kill Devil Hills. Lauren was always interested in marine life, from catching crabs on the sand as a little girl, to studying my aquarium when she...

  18. Refugium Lighting

    Refugiums are a great way to grow Algae for filtration, food, and provide excellent breeding grounds for pods, shrimp, and anything else that would otherwise be destroyed in your Display tank. Refugiums are not always designed for filtration. Some are designed purely for visual enjoyment and others are home to coral frags as they grow larger. They also make great Time Out spots for bad fish and are good places for injured fish to heal, but remember these are connected to your Display tank so...

    What is the most common reason for giving up the salt water hobby? When you search through the endless listings of reef tanks for sale on Craigslist, the majority of tanks are not exactly top of the line. Someone will label “Full Blown Reef” on a tank that is nothing more than a fraction of what the educated reefer would even consider putting animals in.

    To this day one of the most frequently asked questions I get, and actually that many “old time hobbyists” get is “How do I get rid of the algae in my tank. My first question then is “what are the parameters of your tank’s water? Invariably the answer is my tank’s parameters are “perfect”.
