  1. Heating large tanks with your gas hot water heater. Save 40% on energy cost!

    On average, 40% (±15%) energy cost savings over electrical heaters (depending on how efficient your hot water heater is). For my tank (I have an abnormally cold basement), I use 1500w of heaters and temperatures drop slightly at night. I also have a 1000w metal halide lighting system, which takes over most of the heating for 8 hours. But I figure I can say I average 1500w of heating 6 months out of the year, for half of the day. So my yearly heating cost of my tank is approximately $375....
  2. Automatic Frozen/refrigerated food dispenser

    I wanted a way to automate feeding of diverse and healthy foods to both corals and fish.

There have been successful attempts at frozen food dispensers, but they are too complex for my taste. So I made a refrigerated food feeder. The hardest part of this by far was getting the preservation of...
  3. Build a DIY auto filter (Rollermat) for $60!

    Automatic mechanical filtration
    An automatic mechanical filter provides all the benefits of running filter socks, but removes particulates before they can break down in your tank and increase nitrates, and only needs to be changed once a month or less- depending on design. The basic design is a supply role of filter media, and a spool driven by a motor that takes up used filter media. Bulk Reef Supply sells the Rollermat for $400, which is similar in function. I don’t like the design of the...
