    History

    I’ve been keeping freshwater aquariums since I was kid in the 1980’s, and in the 1990’s got to saltwater. I had 20 gallon tanks back then, and after a few years of keeping this size tank I realized I liked the smaller ones. There was just something charming about a small nano or pico reef that I found appealing. I tried a smaller 6 gallon reef, but a few corals took over and became pests. I also had some unwanted algae due to using filtered tap water.

    0.5 Gallon AIO Pico Reef

     

    My wife and I spend a good deal of spare time in what we call our hobby room, listening to audio books. I wanted to be able to look at the tank on my workbench there, so I downgraded to a 0.5 gallon pico! This tank actually flourished, had no pests or unwanted algae. It had its own removable AIO filter area with refugium that I made out of black styrene sheets. I started using distilled water from the grocery store instead of filtered and treated tap water. I also glued dry rock from old tanks together to make a base for corals so I had no unwanted pests. It also had a Masonite canopy I made that just sat on top of the tank.

     

    With this success I decided to go a bit bigger a couple years later. Thus this 2.6 gallon was born! I used my 0.5 pico tank as a model and just took everything that was good and improved it in the 2.6 gallon. I did have a few design flaws at first. I originally planned to have two power heads. This proved to be too much flow for the tank, even turned way down. The higher evaporation was also something I didn’t anticipate, so I designed a PVC pipe automatic top-off system. In June of 2018 the 0.5 pico reef was taken down and the corals moved to the new 2.6 gallon.

    The first year was rough. I wanted to try LPS and SPS, so I went with a low nutrient setup. I fed sparse and also had Phosguard in my media. No fish or inverts except a couple hermits and a snail. After a year of poor polyp extension, bland colors and no growth I was about to tear down the tank. After some research online I realized I had made my tank too sterile. I could go a couple of weeks without needed to clean the glass! I removed the Phosguard, started feeding more and added a small clownfish, to dose nitrate 😄. The Cheato also needed replaced as it was sickly. Things started to get better fast afterward!  Full polyp extension and coral growth started happening with in a couple weeks. At the same time I got a smart power strip and can turn things on and off with Alexa and set a schedule for the refugium light. I just let the tank grow for a few years at this point, picking up a coral here and there to try.

    The AIO made of black styrene is on version 3 now, made in March 2021. This last time I made it fit perfectly flush with the sides of the tank, I made sure all cuts were a perfect 90 degrees and used a thicker sheet to make it more sturdy. It is the best performer yet.

     

    The canopy is made out of a framework of ¼ inch square basswood and black styrene sheet 0.75 mm thick. The original light was a Aquamaxx Prism 300. In April 2021 I changed it out because I didn’t like how to program it, and I was on my third one as LEDs kept failing. The canopy needed redone to house the new Fluval Sea Nano light. I did a much better job building it this time. A used better screws, designed various brackets and printed them on the 3D printer, made sure things were 90 degrees (mostly) and sealed the finished framework well with black spray paint. I left a gap at the top for some ventilation.

    At the same time I made the new canopy, I did away with the PVC ATO and setup the Jebao WiFi Doser 3.4. It took me several weeks of trial and error before I found the 6 ml and hour needed to keep up with evaporation. I’m only using one pump on it for the Kalk+2 but have toyed with the idea of doing some sort of auto water change with two more pumps.

     

    I also got rid of my Pocillopora. It was getting huge and had multiplied all over the tank and was starting to become a pest to other corals.

    Most recent equipment change has been to add a Reef-Pi in June 2021 with temperature sensor. It doesn’t control anything but will email me if the tank gets to hot or cold.

    Future Plans

    What’s next? I’m not sure. I don’t want a bigger one or another tank, I’m happy with what I’ve got size wise. It is easy to manage and getting easier with automation. I‘ll see what more I can do with the Reef-Pi (pH Monitor maybe?) and the Doser to further automate the setup probably.

    This past year due to the pandemic I was asked to work from home exclusively. As the room I’m in doesn’t have a window, I’ve enjoyed looking at my tank as I’ve worked.

    Interesting Fact

    One thing I’m sure some will scoff at is the fact that other than salinity and temperature I do not test any other parameters. I have the test kits, even a Hanna digital, but as long as the corals look happy and are growing, I’ll just keep things as they are and keep doing what I’m doing.

    Advice For Hobbyists

    Research and learn as much as you can from others. At the same time, don’t be afraid to try new things or do things differently (within reason), that is how we advance in the hobby. This is what I did for my past couple of tanks by building the canopies and AIO filtration instead of ready-made options.  Forums like Nano-Reef.com are a great source for ideas and to learn from others. The site has helped me greatly over the years to become a better reef keeper.

    Congratulations. Very well deserved. I’m always so impressed with hobbyists that can keep such beautiful reefs in such tiny tanks. This is no different, I am super impressed. Would love to see a video of the tank.

    Dude, that is amazing. I had no idea a reef aquarium was possible in 2.6 gallons of water. Very cool.
