What Is A Nano Reef Tank?

When you begin your hunt for the best nano reef tanks, this is the most common question that is sure to pop in your mind. Not many people are aware of what a reef tank is. But, don’t you worry, we have got that answered for you.

To put in the simplest way, a nano reef tank is an aquarium with a capacity of 30 gallons or less. The name “nano” to some extent can give one an idea of what sort of tank is being talked about.

The best part of a nano reef tank is that it can be placed anywhere in your house. Your desk, shelf, table all are ideal placement locations. In that light, any person can have a nano reef tank at home. You do not need to have a large place to satisfy your desire of having a tank at home.

You can also install a nano seawater tank to pep up your office or bedroom. All you need to do is get the right pieces of equipment to go with the best nano reef tank of your choice.

Factors To Consider While Choosing the Best Nano Reef Tank

1. Select The Right Tank and Accessories

The size of the tank will depend on the number of fishes, corals, and plants that you will ideally prefer in your tank. The best nano reef tanks come in 14, 29 and 40 gallons. But you need to put in some thoughts before you select the size.

2. Lighting

The most common accessories used for lighting a nano reef tank are Power Compacts. Additionally, Fluorescent light tubes and Metal Halides are superior to other types of lighting systems since they offer a shimmering effect to the water in the tank.

While selecting the lighting system, borne in mind that all light bulbs have separate Kelvins. Though you can use all of them for your nano tank, 10, 12 and 20 actinic are the most common options.

The lighting setup for your nano reef is depended on the coloration that you want for the tank. Actinic lightings generally provide a purple coloration to the water which makes some fishes and coral appear fluorescent.

However, the type of the nano reef will have to be decided first in order to determine the watt per gallon you will need in your tank. For instance, a soft coral reef will require an 8+ watts per gallon.

3. Filter

For proper water circulation, you will require a Powerhead which has a turnover of 20X gallons in the tank. For instance, a 40-gallon tank one will require an 800gph Powerhead.

Though one can use all the filters available in the market for a nano reef, its advisable to use the submerged filters. These varieties of filter come with a protein skimmer that can be used to remove dissolved organic matter.

One can also make use of a mechanical or chemical filter if they have a corny reef. However, a calcium reactor will be required to create the calming effect of freshwater.

P.S All the pieces of equipment must be plugged into the ground fault before they are plugged in into an outlet. Additionally, a grounding rod can be put on the inside of the fish tank as well.

4. Heating

Heating the best nano reef tanks is not a big deal. However, it can become a bit challenging if your house is too cold. Sunlight and general home heating systems are ideal to get the desired temperature in your nano reef. Thus all you need is a small heater with around 50w power or tops 75w. But if you are looking for any specialized option, you can opt for Ebo Jager Heaters since they have been quite successful for nano tanks

5. Natural Filter Method

If you wish to make your nano reef very lively, then it’s advisable to use curvy rocks so that when they are placed together, the corals form naturally. For such a setup, you will require 1 pound rock per gallon, and 5 pound sand per gallon.

6. Location

As mentioned earlier, a nano reef tank does not require a lot of space. Thus all you need is a well, sturdy and solid surface, which is well balanced to take the weight of your fish tank. Ideally, it can be up to 200 pounds, however, it depends on the type and number of fish you will have in the tank. You need to calculate the weight carefully before placing the tank.

Additionally, select a certain spot in the house where human movement is quite frequent. This is because, once the tank is set, it will require constant supervision.

7. Tank Filling

For filling the tank, you need to mix the water with salt. However, do not forget to read the instruction provided by the salt manufacturer.

8. Salt Components

While adding the salt in the tank, measure the gravity using a hydrometer. When it is around 1.023 install the Powerhead in the tank. This will help the salt to mix well.

9. Hardscape Placement

It is important to spread out the rocks as far as possible. This will allow the fishes to swim freely and hide when required. Do not worry about the patterns while installing, you can obviously rearrange them whenever required. After the rocks are placed, level out the sand around the rocks. Follow the same thickness throughout the tank.

Types Of The Nano Reef Tanks

1. Hang or Back Style

This is the cheapest style available for hobbyists to try. However, it is not a very favorable option for many since a hang on back or HOB filter is quite junky and traps a lot of gunk which raises the level of nitrate and phosphate build-up and gives way to an algae outbreak. Such setup also lacks room for a carbon or other chemical filtration system that might be required to clean the water in the future.

2. All-In-One-Style

This is one of the best styles that you can use for your nano reef tank. The best part of this style is that the filter is well hidden at the back of the tank within multiple compartments. Each of these compartments can be used to store different things as per choice or requirement. Some hobbyists use the various compartments to store the bio-balls, filter-floss, skimmer, or carbon.

Unlike HOB styles, these compartments are very easy to use and offer a lot of storage option. Just by looking at the filter one will not be able to notice that the filtration system offers such storage compartments right in the back.

3. Overflowing Box Type

While looking for the best nano reef tanks, one can also opt for the drilled reef tanks with an overflowing option. This option is just ideal for a 40-gallon breeder or much larger tank.

The primary idea of using an overflowing tank is to direct the filtration from the display tank to another tank hidden under the display tank. In such a setup, the water passes through various compartments, for instance, the skimmer, carbon section, refugium section, etc and then return to the display tank.

This type of tank offers more room to place the skimmer, a bigger display area in the tank, and a chance to set up refugium along with macroalgae. It is for these reasons that overflowing box tanks have become so popular.

Tips For Setting Up Nano Reef Tank

1. Leak Test

Once you find one of the best nano reef tanks, you are most likely to be too excited about setting up your nano reef tank. But before you proceed with that, it’s highly recommended to check of any leaks. For this purpose, simple tap water is all that you will require.

2. Rock Adding

Once you are done with the leak test, you can start adding live rocks to the tank. Of course, the primary idea is to put them in a visually appealing way, but do ensure that the arrangement is sturdy. Some people like to use egg crates to place the rocks. However, make sure you leave some space between the rocks and also on the sides of the aquarium for easy cleaning.

It must be borne in mind that rocks are the most important filter in your tank which provides the first layer of biological filtration to the water. In that light, do not just buy 1-2 lbs of rocks for your 30-gallon tank. The rule of thumb is to get 1lb of rock for every gallon of water. However, there is no ceiling on the maximum amount of rock that you can add.

One can also choose live rocks to be placed in the nano reef tanks. Live rocks are just plain rocks that have been in a setup tank for some time and have thus allowed beneficial bacteria, and other living organisms to grow on them.

Ideally one should get 30 lb of live rock for a 30-gallon tank. However, if that is not feasible, 5 lb of live rock paired with 25 lbs of dry rock can be a good alternative.

3. Sand Layer

After you are done with the rocks, begin with a layer of live sand, that is if you are adding sand to your tank. It is not crucial to add sand to a nano reef tank. However, most hobbyists do that for aesthetical reasons.

However, if you are planning on adding sand in your tank, do not get something too coarse. Coarse sand obstructs the passage for many fish. Additionally, do not opt for sand that is too fine, your powerhead might blow it around.

Ideally, the layer of sand should be 1.2 to 2 inches deep. After placing the sand layer, you can place the different pieces of equipment like the heater or filter, however, do not plug them yet.

You can also add live sand in your tank. Like live rocks, live sand too has organisms living in it. So if you are using dry rocks in your tank, adding a bit of live sand can be a good option.

4. Water

In the next step, you can begin by adding water. However, make sure you are doing that slowly, or else the tank might get extremely cloudy. However, if you are not using premix saltwater in your tank, you need to add reef salt to your RO/DI or distilled water before adding the mix to the tank.

In addition to mixed saltwater, one will require plain RO water for topping the tank on a daily basis. Thus it is a good idea to have some RO handy all the time. As water from the tank evaporates daily, the salt residue is left behind increases the salinity level of the water in the tank. Thus RO water is required to be added in the tank when the water inside the tank evaporates.

Many hobbyists use a refractometer to determine the salinity in the water content of the tank. Ideally, the salinity level should be at 1.025. If the salinity level falls from 1.025, then more saltwater should be added instantly. If the salinity level is much higher than 1.025, then some water from the tank should be replaced with plain RO water.

Finally, you can plug the appliances and wait for the water to settle. Your nano reef tank is now ready to function!

Cycling the tank before use is another crucial step that you must take. This step should be taken up before placing ANYTHING. It is not advisable to include carbs, snails or fish in the tank until it is cycled properly.

Tanks usually go through a nitrogen cycle. Then it leads to the production of ammonia which then converts to nitrites and finally into less toxic nitrates. Once you have almost zero percent of ammonia, nitrites, and under ten nitrates, it is okay to assume that your tank is done cycling.

Errors To Avoid

Of course, the setting up process is easy said than done. There are a few common errors that many hobbyists do. Moving the tank quickly, not doing sufficient research, and opting for the incorrect tank are most of the common errors that are quite prevalent.

The only solution to all these problems is research. If you are planning on getting a nano reef tank at your place, do make sure you are absorbing every piece of information there is to intake. Only powered with the proper knowledge will you be able to keep your piece of reef happy and healthy.

Additionally, make sure that the heater is turned on all along and the temperature of the tank should be set at an optimal level without fluctuation.

Another thing to do is to check the salinity level of the water at least once a week if not more frequently. Additionally, the powerhead or wavemaker should be placed facing slightly downwards so that it does not stir up the sand in the tank. Such a setup makes way for ideal oxygen exchange which is essential to ensure the wellbeing of the life in the tank.

Reef Maintenance

Once you have set up your reef tank and it has been functioning fairly well for the past few weeks or months, you do not have many things to worry about. However, you cannot stop your research at this juncture.

You have to know how to maintain your tank properly. For maintaining the optimal health of the tank, make sure you are changing the water partially every week or so if not often. Additionally, check for any disease or weakness in the water quality of the tank. With all that taken care of, you can enjoy your reef tank in bliss!

Best Reef Tanks: What’s Your Pick?

Now that you know all that there is to know about having a nano reef tank, you don’t have to worry about much. Begin the process by choosing the best nano reef tanks from the list of product provided above, select the pieces of equipment to go with it and you are set.

However, keep your research on if you want your nano reef tank and all the aquatic lives in it to be healthy. All the very best!
