dimensions: 3ftx3ft cube, about 68 inches of total height

Got this tank a few weeks ago from @Coral reefer for my school classroom, but major problem for me - it doesn't fit through doors without a complete breakdown each time! Not to worry for me, I was able to get another 150 gallon for the classroom, but my effort is to your benefit as I gave the...

Ah I wish I remembered the name of the stand from the person who I got the tank from, but all I remember is that whoever made it they are now out of business :/

Tank taken, enjoy @Hydrogel !

The wife already turned him down, poor guy

Been sitting in my garage for a few months after upgrading to a larger tank. Free for pickup in redwood city. Comes with tank, stand, sump, and most of the plumbing needed. In very good shape, cleaned out, and ready for a new home!

Good to know - do you know how old they were approximately when they failed? I am thinking this tank has been used for a few years, and the seams seem solid if its made it this far

Also, @Coral reefer how old is the tank? Possibly @xcaret can answer as well. Thanks crew, looking forward to getting some students to clean it! Haha!

The tank made it to the school in great shape, and I am proud to report that even without cleaning out the remaining sand and water, it did not stink up the staff hallway lol. I did take the sump home for some citric acid spa treatment, and the build will be a slow process while we decide where...

Thx, department head was asking about the size

What is really cool is we are looking at setting up tanks for long term coral monitoring and experimentation for our upper level research course, so this would be perfect! I have my fingers crossed!

Hello! I work at a high school in the south bay, and am in the process of hunting for tanks to set up in the classroom - this sounds like it would work great for what I am looking for! PM incoming with details.

Oh very much so, especially the pH and salinity probes, but they get cleaned with a soft brush every 4-6 weeks

Very proud of my tank, and especially my chiller, through this crazy heat wave we are having. My tank is in the garage, and temperatures in there reached 100 degrees both of these last two days. I have also been very lucky to avoid the power outages so far, knock on wood! In my tank parameters...

Dang what a deal. I love my EXT 50, really high quality tanks.

Available Mon-Wed!

Hello! We were in communication about a while ago about you donating your old 75 gallon to my classroom, and I just wanted to follow up and check on the status of your tank transfer! Let me know at your convenience, thanks again for your time!

Hey this is really interesting, I've had issues on my alk dosing - if I dose soda ash, my alk gets too low unless I dose enough to have precip events, and if I dose baking soda my pH drops too low. Where'd you get the idea to mix them, and how is that going for you? How did you come to the 2:1...
