So, you know the type of fish that you want and the decoration and plants you want to be installed. These are the factors that will help you determine the size of the tank you’ll need.

Some brands come with water heaters and thermometer to keep an eye on your reef tank temperature. In case your tank comes bare, or without a thermometer or heater then you’ll have to buy it separately.

Selection of corals

Underwater gardening can be as much fun as regular gardening but without the dirt. Corals are some of the most beautiful and colourful creation found underwater. Selecting the right coral is as crucial as choosing the proper water treatment for your aquarium.

You need to have the right set up to be able to mimic the natural habitat for your coral and fish. Nano reef tank setup can vary depending on the product but they all follow a silent order. Here are ideas to help you set up a reef tank:

Once you have your location, nano tank, and all the necessary accessories it is time to put everything in order. Wash the tank and everything that will go into the aquarium with lots of clean water and let them dry. During this stage fill up the reef tank with water and check for leakage.

Prepare water for your aquarium. Use RO water because tap water contains chlorine which can be dangerous. Once you have your RO water add in the reef salts and test the salinity. Always follow the guidelines of the reef salts manufactures.

Setup your aquarium

Position your reef tank where you want it and start installing the reef tank lights, filters, heater and thermometer. With your aquascaping reef tank ideas decorate your tank to how you want it. Heat up the water to the optimum temperature for your reef tank.

Put your live rock and sand the way you want it but remember to space the live rocks properly. The thumb rule here is one gallon per a pound of rock.

Fill up you nano tank with the salty RO water, and start the cycle. You will have to test the nitrate, nitrite, and ammonia levels every day. We recommend that you do so for a week without adding you livestock.

Add you fish
