Hey all! First of all, for those of you who have been in on my big tank drama from the beginning- thanks for all the encouragement! For those of you who don't know me, I am an old timer who has been in and out of the hobby for several years. It has always been a dream to have a large (100g+) planted tank, and after many fits and starts, it looks like it is finally going to happen before the end of this year. Please stay tuned for updates and feel free to give your feedback once I am ready to scape it! Initial thoughts are below: The tank is a standard glass Visio with black rim: 72" wide x 24" deep by 18" high. It weighs (approximately) 9 million pounds. Ideally, I would have gotten a custom acrylic tank, pre-drilled, etc. but that was never going to be in the budget, and I was tired of putting off my dream. I will be building the stand myself. I have gone from a fairly basic design, to one that will really test my woodworking skills, but has been approved by two different experts to withstand just about anything short of "the big one". It won't have a lot of beauty- but it will be solid as a rock if I can pull it off. It will be shorter than most stands, at only 26" high, in order to meet the wife's request that the entire tank be below the level of the window it will be in front of. Right now I am still debating between painting the back black, the same gray as the wall behind it, or going with a frosted backing. I will be using 2 FX4's for filtration, due to the reduced height inside the cabinet. I will try for an inline heater on one and an inline CO2 reactor on the other. I am considering a UV sterilizer, too. Also because of the limited space, I may only be able to get away with a 5lb tank underneath... I am still debating how sensitive/CO2 dependent I want the plants choice to be. A 5 lb tank on 135g is going to get used up pretty quickly. For lighting, I think I am settled on 3 x AI Prime, suspended from the ceiling. The AI Prime seems to be a good value in performance, customization, and cost- plus as a bonus, they come in white, which will help them blend in to the window behind them. In addition to the plants, the stars of the tank will be a substantial school of Bolivian Rams- 9-12 is the current plan. I wanted a fish that was big enough to make an impact in the tank, small enough I could keep several of them, and unusual enough that you don't usually see them in groups. I have been collecting rocks and wood every time I see something I like. My desire is to have a pretty good amount of open space with lighter sand in the front and a curvy patch near the middle to create depth and make the Bolivians feel at home. See my amazing artist’s rendering below. I would love some advice on the best way to build the "wall" between the planted areas and the open sand- I have never done that before. I am thinking to use red lava rock (and moss) for that, as it will fit closest with the palette of the other rocks and natural color gravel I am using. I will not be using any premium substrate, but following the same formula I have always used: soil, fluorite red, Sea Chem "Peace River". Sorry, dark substrate has just never done it for me. Here is where the tank will live. Please ignore the internet mess that needs to be moved. The dimensions are so nice, it doesn’t even look that big, does it? Originally my wife requested that the top of the tank be even with the bottom of the window molding- I was able to negotiate up to the bottom of the window itself. That will make it really easy to work on, at least! Here is just a basic sketch of ideas, using only plants I already have growing in the two small tanks. Thanks to them, I think I can have the big tank pretty close to fully planted on day 1. Here is the current stand plan: Here is the hard scape I have been collecting. I love the colors of the rocks, but I have to admit- some of them are that “glass rock”. Shiny, and sharp as heck. I am going to take a sander to them and see if it helps. I think that serves as a good introduction. Comments and questions are welcome. Stay tuned for more!
