Brand new to reefing. Basically there was an office I worked in that had some tanks and I fell in love with the triggerfish and the way they swim. Always planned to have a tank in my own office one day. Don’t plan on having my own office any time soon though so convinced the wife to do an in...

Hi all, any suggestions for adding/changing this stock list?? Tank will be a 200x120x60cm - 380 Gallon Display with a 200x30x60cm - 100 gallon sump behind it. In the sump I'm planning on a chaetomorpha refugium, a bubble magus curve 9+, some live rock, filter pads and a carbon reactor/uv...

My Waterbox Infinia 275.6 turns up tomorrow. It is going to be in storage whilst I plan the switch over from my current 6ft (unfortunately it is going in the same spot). As I have mentioned on another thread, I am building a mixing station in my outdoor shed so I can automate the top off of the...

Hey what’s up everyone, I’m relatively new to the hobby and needed suggestions on a new tank I’m currently planning. I currently have a 10, 20, (2) 30’s, 45, 55 and a 75 gallon already setup. As I was browsing the deep dark web (just kidding) I came across a couple of tanks that were close to...

Hey everyone. Hope all is well in your reefing world. I'm James Pergamo from 5th Alarm Corals in Long Island NY. I've gotten to know so many of you over the years from shows and forums and social media, I felt this new project deserves a true catalog build thread. I'll try to document the best...

Hello Reef2Reef community, Firstly, pardon any newbie mistakes in this post; I'm still getting acquainted with this platform. A bit of background: About 5 years ago, I was the proud owner of a small reef tank. However, circumstances led me to sell it. I also have a history with freshwater...

Here is the start to my 310g Planet Aquarium Mixed Reef! Thinking of doing starting a YouTube channel and sharing the journey.

So it looks like my Reef Savvy tank is finally on the build table and am excited to finally get this build moving forward again!!!! My question is how much lighting do you think I should have on this tank. For this build I currently have 4 qty Radion XR30 Pro's (Red) that are planned to go...

Hi everyone, my wife and I are in the beginning stages of designing our forever home to be custom built. One thing we know we want is a large DT, somewhere in the 180-360 gallon range. Of course, the final determination of the size of the tank will be based somewhat on the available space for...

Sump room behind tank, or, in basement? Hi everyone, my wife and I are in the beginning stages of designing our forever home to be custom built. One thing we know we want is a large DT, somewhere in the 180-360 gallon range. Of course, the final determination of the size of the tank will be...

Big things are happening! My ultimate end goal with this tank is an SPS dominate mixed reef that’s as stable, automated, and low maintenance as possible. Easier said than done, certainly. The tank Has arrived! Now to sort out a way to get in place and on the stand……

Short and simple. What do you all think, do I own a queen angelfish, a blue angelfish, or a hybrid Townsend?

Hi everybody, 180 gallons currently using a single Hydra 32. As I expand my aquascape, I decided to switch to 48" T5HO. My question is regarding the schedule and making sure I don't stress too much my corals during the transition. I decided to go with ATI 3x aquablue special, 2x purple plus and...

At the urging of our site host, I've been asked to make a 'member build' thread. Some very cool work here from extraordinary talents, so mine is modest at best, but perhaps it will provide inspiration to others. 5/31/22: I purchased the CADE1800 from AlgaeBarn and to my surprise upon arrival...

Hey everyone I have had many tanks, but now I get to join the large aquarium crew with a 180 display not including sump first step was sanding it and polishing the tank which took over 3 days Then building the stand to hold the whole wait of the tank. Then the process of sanding the stand and...

Hey Everyone, I am starting a little late to the build post. I am brand new to the world of aquariums but have chosen to dive in head first. Build List ProStar Rimless V2 200 Gallon Aquarium w/ BLACK Stand - Pro Clear Aquatic Systems COR-20 Intelligent Return Pump (2000 GPH) - Neptune Systems...

I have a roughly 275 gallon system, 210 DT and a 65g sump (probably closer to 250 honestly, neither is filled to top) I travel fairly often and am the main person that cares for the tank. my evap during cooler months has been 1-2 gallons a day, I can only imagine the summer months spiking to...

Hello all, This is going to be a very fun build and probably not the best idea I have ever had. ;) I have not been around fish tanks in over 15+ years I have owned a few but nothing to crazy. The most advanced tank I had was the first RSM250 haha and that was a good time. So this will be a...

Hi All, I reentered the hobby last March after almost a 10 year hiatus (Formerly W1dude on NanoReef). My GF convinced me to set up an 80g in our living room. Well, fast-forward to a new house and 1.5 year later: We are 1 week out from delivery on a 72" x 36" x 25" tall glass build. The...

We bought our house with the basement mostly finished but have remodeled almost everything in the last few years. The basement is long and the different areas never seemed cohesive so I was lucky enough to get my wife on-board for a room divider aquarium! The tank itself is 72x24x30 custom...

New to R2R, heard about it and was also investigating some ideas for my freshwater system. Have been in this hobby for more than 25yrs, mostly FW. Over the past few yrs I focused on nature aquarium style and detailed aquascape with plant selection. I kept a SW cube few yrs back with toadstool...
