$1,127 Build List

Okay, so this is not a cheap build.  Essentially a 20-gallon aquarium, but with a price tag of over a grand?  Yikes.

So if you are not interested in spending this much, check out my $427 Build List, which is the exact same tank, just $700 less.

So what makes this build so expensive?  Three things:

  • 2x high end LED lights,
  • an auto top off unit,
  • and a $300 stand.

Take away those items, and you save $700.  But for those of you who have some extra cash to spend, check out the build below. The Innovative Marine Nuvo Encore is 20 gallons in total, but broken up into two 10-gallon, fully independent low-iron glass tanks.

The Pro Bundle from Marine Depot comes with the mesh screens, return pumps, acrylic media caddies, filter socks, and media.

From the manufacturer

The NUVO APS Stand sets new standard in aquarium furniture.

Aluminum has been a tried and true element for custom commercial stands, because of its versatility, strength, and the fact that it is very light weight. Innovative Marine just brought that technology to the aquarium industry to create a truly singular aesthetic aquarium stand that is modular in construction, easy to set up, and is resistant to corrosion and swelling in both fresh and marine environments.

Finally, an aquarium stand that may actually outlast your aquarium!

Here’s the thing about heaters: they all fail eventually, so keep that in mind.  There are several different types of heaters, primarily glass, ceramic, and titanium.  I’ve always used glass as they are inexpensive and heat the water quickly, but they are also easy to break (I’ve shattered at least two, maybe three!) 

These Eheim Jager heaters have been my go-to since the beginning.  I’ve never had one fail on me in over seven years (with proper maintenance of course).  This heater does need to be calibrated, so be sure to pair it with a digital thermometer to narrow in on the temperature.

By the way, this 20 gallon tank requires 2x 50 Watt Jagers!

Auto Top Off

From the manufacturer:

Why Choose Duetto ATO ?

With huge features jammed in a tiny package, the Duetto is the perfect ATO for your aquarium. XP Aqua’s proprietary dual-optical sensor packs two precise level sensors in one incredibly small package. In addition to keeping your water level constant, the two sensors also work in concert with the intelligent QST programming to help prevent overfilling.

All the installation parts are included and a magnetic coupling allows you to easily mount or adjust the dual-sensor. Installation takes just seconds so you can spend less time working on your aquarium and spend more time enjoying your aquarium.

Optional Items

Salt Mix

There are so many different types of salt mix on the market, and I’ve tried a ton of them!  They all work fine, but they vary depending on your livestock plan.  

Most of us start out by buying saltwater at our LFS (local fish store), because purchasing distilled water from the grocery store is expensive, or buying the necessary RO/DI filter costs even more.

But you can save a bit of money and hassle in the long run by mixing your saltwater at home.

For this $427 build I recommend this salt, as it is good for FOWLR (Fish Only With Live Rock) systems, or tanks with a light stocking of corals.

Temperature Controller

Again not a necessity, but for around $35 you can control your tanks temperature to within 0.1° F.  I live in the desert, so in the summer I run a fan to keep my aquarium cool.  I plug my fan into the “cooling” outlet and my heater into the, you guessed it, “heating” outlet, and my tank stays a constant 78° F all year round.  Plus, this controller has a built in alarm which alerts me if my heater or fan ever fail.  Not bad for under $35!

Test Kit

A basic test kit is a must.  It is most important when you are starting your tank so you can test for when the nitrogen cycle is completed.  While not always the easiest to read, this test kit is affordable and will give a ballpark which will be good enough.

Calcium / Alkalinity Test Kit

If you are only planning on keeping fish in your saltwater aquarium, then you don’t need to worry about calcium and alkalinity.  But SPS (small polyp stony) and LPS (large polyp stony) corals, as well as invertebrates such as snails and crabs, need calcium and alkalinity to build their skeletons.

Sand is not essential by any means, and there is a trend in the hobby toward a bare bottom tank.  That being said, sand does lend not only a nice aesthetic, but it aids in biological filtration, and provides a refuge and food source for certain creatures.

There are many types to choose from, but you only need a 10 lb bag for this build, and stick with CaribSea.  My favorites are the Arag-Alive Special Grade, Arag-Alive Fiji Pink, and the Arag-Alive Hawaiian Black.

Surge Protector

I currently own four or five of these!  They are my inexpensive answer to an expensive controller.  I mount these either under my stand, or somewhere out of the way and then label each cord.  That way, whenever I need to do maintenance, I can just flip the individual switch to turn off the appropriate piece of gear.  I love these things and will keep recommending them well into the future!

Cleaning Brushes

This may seem like a silly thing to add to a build list, but I have found that these two brushes do the brunt work of my cleaning.  They have a stiff bristle and have held up for me for many years now. They work much, much, much better than a toothbrush!


I like this AquaMaxx dry live rock.  It is environmentally sourced and you can buy as little as 10 lbs (perfect for this tank).  But it is not my favorite.  I prefer the CaribSea Life Rock (10 lbs), mainly because it has a natural coralline color. But it is quite a bit more money.

Rock is important for a few reasons:  it provides a place for beneficial bacteria to colonize; it provides hiding places for your livestock; it gives you places to mount coral; and it is better than looking at an empty tank!

You don’t need a ton for this small tank, and I think 20 lbs would be sufficient, but if you buy more it will just give you more options!


Gravel Vacuum / Siphon

For this build, I would probably go with the 9″ mini or medium size.  If you get the mini, be careful because it will be more likely to siphon out your sandbed and it will get clogged by more course types of sand. And and if you go with the large, it will drain the tank too quickly!

A gravel vacuum is a must in this hobby for water changes.  It is the easiest way to start a siphon and drain your water, while at the same time vacuuming your sand bed free of detritus.

Thermometer / TDS Meter

There are cheaper thermometers out there, but I haven’t found a less expensive digital thermometer and TDS meter combo. 

Pocket Sized TDS Meter w/ digital thermometer in aquarium-specific packaging.

The world’s smallest and lightest TDS meter also comes with a built-in digital thermometer. It is a true pocket size meter, comfortably fitting into a shirt pocket without adding bulk. The TDS-4TM-A comes in an aquarium-specific retail-ready packaging.


It does need to be calibrated, but rather than buy an entire bottle of calibration fluid, just go to your LFS (Local Fish Store) and ask to use a few drops of theirs!

I’ve also heard that you can use RO/DI water to calibrate to zero, but I’m not sure if that is as effective as using a 35ppm saline solution!
