    History

    After operating a 50g show rectangular reef tank continuously for nearly 10 years, I felt it was time for a change. In 2008 a co-worker's challenges with his new 10g nano reef tank inspired me to give one of these small nano tanks a try, so I started to peruse the various reef aquarium related sites looking for an appropriate sized all-in-one tank. I finally decided on the CAD Lights 12g AIO due to it being just the right size, made of glass, topless, pleasing proportions, and decent equipment at a reasonable price. My goal was to develop a tank that could do well with minimal equipment and low operating costs, while still providing an environment where reef organisms could thrive.

     

    Once the tank arrived and I got it set up, I proceeded to add smaller pieces of live rock and some live sand from my still running 50 gallon aquarium. Using this matured material resulted in no cycling to speak of, but I still waited a few weeks before adding some mushrooms and zoanthids. I then added a typical cleanup crew of a few hermit crabs and Astrea/turbo snails. Things went well for a few months as I slowly added all different kinds of corals, since I was shooting for a typical 'mixed reef' look. I tried adding a Fire Shrimp but it was too much of a pest, always stealing the corals' food, so I gave it away to a local reefer. The snails never lasted long so eventually I ended up with just the hermits.

    I had some real trouble with large amphipods eating most of the zoanthids, which I finally solved by adding a Black Barred Convict Goby (Priolepis nocturna). As I acquired more livestock I met the dreaded 'Red Bugs'! I lost a few of the Acropora frags, but a Green Slimer seemed unaffected. Then I made the mistake of buying an injured Blastomussa that I thought I could revitalize. Very soon thereafter I had a 'Brown Jelly' infestation that took out the last Acro, the Bali Green Slimer, and nearly all the LPS (Acans). I'd say this was the low point, but I saved what I could and carried on.

     

    Dinos, algae and Cyano were next on the 'Hit Parade,' and at this point I stopped to really think about what was happening in the tank and what was needed to improve the situation. Since it was clear that nitrates and phosphates were fueling algae growth, I started to regularly vacuum detritus in small sections from the shallow 1" sand bed with each water change, as well as using a turkey baster a few times a week to blow out the buildup from inside the live rock. It took a few months to eventually get things cleaned up to where nearly all the pest algae had finally disappeared.

     

    I had no fish and I wasn't feeding the tank during this time which, unfortunately, didn't sit well with the existing pasty-looking corals! But, once I had the maintenance schedule dialed in, I started to feed the corals more and added a few fish, and things picked up. Then the stock T5 ballasts died so I fitted a bunch of the Ecoxotic LED Stunner Strips since they fit perfectly in the stock canopy. From then on it has been a series of subtle tweaks to the system to determine the optimal feeding and lighting to get the tank to where it is today, five years on.

    Major Changes

    The only major change to the system was one born out of necessity when the stock T5 ballasts malfunctioned. Ecoxotic LED Stunner Strips were added since they were a perfect fit for the existing canopy and produced very little heat. Recently I added a DIY LED strip to add some additional wavelengths and provide a modest increase in the lighting intensity.

    Inspiration & Goals

    Inspiration has come from many sources, but I'd say especially from seeing what has been accomplished by some very talented and dedicated nano reefers in this community. As for goals with this tank, I'd simply like to keep this system running optimally for a few more years and observe how things progress over time.

    Disasters & Regrets

    My biggest disaster was an outbreak of 'brown-jelly' disease which destroyed most of my LPS corals after the first year. I attribute the outbreak to a combination of poor water quality (high nitrate and phosphate, primarily due to not removing detritus regularly) and the addition of an unhealthy LPS specimen. When I think back, I really can't find any regrets since it has been a very educational and rewarding experience.

    Advice For New Hobbyists

    If I were to look for a few key words for success in this hobby, the most important ones that come to mind are 'patience' and 'stability'. Patience refers to allowing the natural cycles to become established and adding organisms slowly. Stability refers to keeping parameters within acceptable ranges and stable over the long-term. Keeping these concepts in mind throughout the reef keeping experience will be most helpful. Research is critical to success. Question everybody who has experience and carefully review the most successful tanks to determine their best practices. But above all, enjoy and learn from the journey.

    Thoughts On...

    Running A 'Natural' Nano Reef System
    Over many years of aquarium keeping I've exclusively used a 'minimalistic' approach. Using this concept on a small nano tank has worked out well and has ultimately resulted in a very stable system. My best results to date are largely due to consistent maintenance practices, attention to parameters and sufficient coral nutrition.

    Acknowledgments

    Nano-reef.com has been a great 'home base' for anything nano related and a big 'thank you' to all the many members for making the nano reef keeping experience a much richer one. I'd like to especially thank Christopher Marks for hosting this site and the very unexpected, yet pleasant surprise of selecting this tank for this month.

    I've been following your tank's progress and you are off to a good start. You'll likely run into some 'challenges' as we all have, but once mature the system should end up being quite stable.
