I think i finally feel like i can start to post a build thread and have it result in an actual running tank within 2 months. Feel free to comment, even teasingly mock or dispense advice if you like. Thanks and being a member of this group has been a lifesaver! When my wife and I bought our first house in late march, i began scheming and dreaming of building a reef tank. I had dabbled in the hobby back in college, but 20+ years later and the thought of having a permanent space brought the old fever roaring back. Now the first problem was- i knew i wanted the tank in the basement as the bedroom would be too loud, and because the house doesn't have central air (we are now getting it), the basement seemed like the best place to go. First problem though- That was what the basement looked like.. so we went to work We aren't quite there yet, but getting closer... Drywall is going up tomorrow and then we have to level the floor and install some flooring.. but then.. then.. the space will be ready. I bought a used 125gallon tank with a stand from craigslist. I wish I had been a little more patient since i bought it in March and didn't wait to see the Classifieds here. The tank is in decent shape, but i will be getting some glass polishing compound since when we cleaned it, we likely added some small scratches. The plan is to drill and use a BeanAnimal system for the overflow http://www.beananimal.com/projects/silent-and-fail-safe-aquarium-overflow-system.aspx Originally, i was going to use an acrylic overflow box that Jlanger made for me, but i have since decided to use a coast to coast glass weir. I still need to order 2 72" long 1/2" thick glass pieces. If anyone has any local places to recommend, let me know, otherwise i will have to order online. My biggest worry atm is the stand. The plan was to use a 40gallon long as a sump, but the stand is constructed in a way that i couldn't fit it through the stand, and likely couldn't fit much in. I took out one of the supports, but now that i have the stand out, i am a bit worried it may not be constructed well. This is the stand on its side after i removed one of the supports. Here are some other angles.. Anyhow right now, i will likely reinforce the stand and add the support after putting in the 40Gallon Long sump, though if a reasonable stand comes along i might pounce on it. I am not known for my patience so after seeing some of the member aquariums from Grigor and going to the Swap, i decided to get something going. I used my future sump as a place to cycle some rock to cut down on the cycle period for the eventual tank. I then used some lighting and added a clean up crew after it cycled. I may not have fish or corals, but at least i have snails and hermit crabs to stare at from time to time. It is nicely cycled now after the algae bloom, and the clean up crew seems to be doing well. Some other plans- Lighting- Currently have a used Maxspect Razor + a used AI Hydra. I will either pick up another one of those used if available, or go ahead and pull the trigger with a BuildMyLeD high end version. Filtration will be LR and a ATS from https://www.algaescrubbing.com/ . I am still debating using a protein skimmer, but i thought i would try without one if possible as it would cut down on my worries about real estate and besides, the stories of smelly skimmate is making me think i should at least try the ATS side of things. Flow- Using a MaxSpect Gyre, and perhaps a Koralia, or Jebao powerhead. (I have the gyre already, debating what other powerhead to use). My return pump is an Eheim 1262 pump. And yes i am using RO/DI water.. Planned livestock- Fish- false percula clown pair Yellow assessor Bangai cardinal (maybe a pair, unsure) Yellow Watchman goby with pistol Shrimp pair of hte hybrid cleaner gobies from ORA or possibly ORA dotty backs I am also considering a fairy/flasher wrasse as well eventually if i ever get enough of copepod population, a mandarin, though that won't be for another year at least. For corals for starters- frogspawn/Torch (or any suitable coral that the clown may pair with) gorgonthian some zoas/palys, though i would like to avoid the extremely toxic ones if i can. Green star polyps various mushrooms Brain coral Eventually a nice clam. Other potential corals would include xenias, and leathers. My hope and plan is to start small, and let the corals grow themselves out.
