I am wishing to document my journey with you all. Hopefully there will be more up’s than down’s, but willing to share (and learn) nonetheless.

I’ve always seemed to acquire secondhand reef tanks, but this will be my first new one. I decided to start from scratch and get a brand new Red Sea Reefer XXL 750 in white. It’ll be replacing a Silver Red Sea Max 130 that’ll be converted into a quarantine tank.

To get ready for the arrival of the tank, I removed the TV in the den, applied a fresh coat of paint, and taped out the final resting place of the tank.

I am likely going to make the tank see-through, so paint choice was important. I went with Behr Marquee Chinese Jade in eggshell. I’m hoping that color works well with the see-through concept.

I am fairly lazy/busy (not good in this hobby) and I absolutely hate going down to the LFS and getting buckets of RODI water. I figured acknowledging my laziness is the first step in making an effort to combat it. In doing so, I needed to design and construct a saltwater mixing station.

upload_2018-12-22_17-18-34.jpeg


This system accomplishes the following:
  • Upper Tank RODI Fill
  • Upper to Lower Tank RODI Gravity Transfer
  • Lower Tank Saltwater In-Tank Recirculation
  • Upper Tank RODI Gavity Bucket Fill
  • Lower Tank Saltwater Gravity Bucket Fill
  • Upper Tank RODI Pump to Tank via Hose
  • Lower Saltwater Pump to Tank via Hose
All of this is powered by a Pan World 50X.

Now (because my laziness knows no bounds) the next step is to run tubing from the garage (where the mixing station is located) to the den (where the tank is located). This is about 60 feet. I plan to set up a Neptune DOS and run black tubing (old saltwater removal/disposal) and white tubing (new saltwater feed). Since I’m in the attic, I’ll run some blue tubing (RODI feed), but I don’t plan on hooking that up yet as I’m nervous about live-feeding RODI top off.

I already have holes in the wall from my wall-mounted TV, so I’ll just repurpose them for the tubing feeds.

Nice you will love the tank I just got my 750 on the stand a cpl days ago.
funny thing I decided I would have a nice big reef instead of a TV in the place too.
you will love this tank its amazing! by far the nicest set up I have had.

Dude this is bad butt. I would love to do the same but here in wyoming even the saltwater would freeze in the garage.
its a perfect think to do with your TV cables holes! I must admit a bit jelly there...haha

So, what is a “hybrid barebottom” tank? I’m not really sure, but in my mind’s eye, it is going to be a barebottom tank with Tonga Shelf on the bottom glass made to look like sand. This will allow me to have ridiculous flow and not have to worry about sand flying around. It’ll also leave me a ton of room to run fields of my favorite coral (cyphastrea).

Step 1: Purchase the largest plates of Tonga I could find. Here is the original mock-up. It’s going to end up much different, but it conveys the concept well...

Step 2: Drag them around my driveway and look like a freak! My neighbor seriously stopped by and asked me what I was doing.

Since this will be sitting on bare glass, I ground off any nubs with a grinder, then used the concrete on the driveway to perfectly “plane” the base flat. This offered no wobble and a nice flat surface with a lot of surface area to sit on the glass. You can see the example on the one I have flipped over...

Now, one of these plates had a massive hollow cavity beneath it. Sadly, it would not be visible from the front, so decided to knock a hole in it and create a cave.

The “cave” isn’t done yet and I’ll get some progress photos up as soon as possible.

I grew up in Montana and know what you’re talking about!

I looked through your build thread and saw the snow. Wow!

It can get cold in Northern Nevada, but it is manageable and I am hoping the tubing in my attic will be ok. My house is on a slab foundation, so the attic is the only option. I might run the tubing in PVC and insulate it just in case.

oh yeah so you know what that I am talking about with the cold then. :D hmm you might be fine but one long cold spell could frieze a line of course it would be the dirty water out thus making a big mess. if you can i would just insulate it while you are doing it just to be safe.

oh on a side note maxspect released there new like up the 300's but they will not be available until Feb. I got 2x 230 for my 750 but thinking I might trade up for the 330. my build is going slow as you saw. so might just work... just food for thought in case you did not know.

loved that your neighbor came to ask what the heck you where doing dragging around a rock in your driveway....priceless should of told him cross fit..lol

I ordered my tank on 12/8 and it was supposed to deliver on 12/21, but it never showed up. I am in the process of trying to track it down.

In the meantime, can you string a measurement from the side of the tower to the inside edge of the glass?

I want to mount two Maxspects on each side of the tower on the back wall; making four total. Keeping in mind I already have two 280’s and two 250’s, what I would really like is four 280’s, but I was afraid there wasn’t enough room. Finding the inside tank dimensions was brutal, so I threw caution to the wind and bought two of each (I should have waited).

In the meantime, I’ll open up the 280 box and get a measurement off of the powerhead.

Base Tonga almost done...

upload_2018-12-23_16-31-24.jpeg


I’m envisioning a “river” or gorge winding down in between the two plates.

I need to “roughen up” the cave to make it look not so man-made, but it turned out kind of cool.

upload_2018-12-23_16-34-23.jpeg


Now that the base is roughed in, time to work on the main structures.

upload_2018-12-23_16-35-44.jpeg


This will likely go through many iterations, but I am looking to build “fingers” sprawling down over the base rock.

upload_2018-12-23_16-38-7.jpeg


I’m not sure what to do with the other plate. I’m looking for sprawling fields of Montipora and Cyphastrea, so I need a lot of flat surface area.

Prefer the term "efficient" instead of lazy, :) great looking build so far.....nice Dillons, I had a 650 not too long ago and loved it.
Thanks Hulley... I can/should insert “efficient”!

Ahhh, the Dillons... yes... my “other” hobby that drains me of money!

Yep, I've consolidated and didn't use them much although I'll probably end up with another 650 and maybe a Rock Chucker, who knows? :)

I still save my brass!
