3. Plan and Budget your Future Aquarium

Planing and budgeting is essential for every project. Reef keeping is no exception, to the contrary it is rather complex hobby with many variables, components and choices.

Following articles will help you envision, plan and understand the prices of saltwater aquariums.

Learn from my mistakes

I planned my first 4ft aquarium towards a 4ft wall. I regretted that for the next 3 years until I moved to a bigger system in a different location. Why? It was just too tight, there was never enough air circulation behind the tank, no place to clean the glass. I should have used 3ft system in that space.

Research what fish and coral you want to keep

It is always best to have a clear vision about the fish and coral species you would like to have before starting to buy any equipment. If you plan keeping larger fish such as Pacific Blue Tang you need to budget for large aquarium to accomodate them.

For corals, the larger the aquarium is, the easier it is to keep corals happy. Larger water volumes are less prone to dramatic fluctuations, and corals thrive on stability.

4. Choose the Best Equipment for Your Aquarium Setup

Selecting appropriate equipment is crucial for creating a stable and healthy environment for your marine life. You can either choose All in One aquarium, which will include most of the necessary components and make the initial build easier for beginners. Or you can build your system from individual parts, starting from empty “glass box”. In either way you should first make sure you understand all te essential components and how they work: 

  • Aquarium Tank: Try to get the largest tank your space and budget allow, as larger volumes are more stable and forgiving of parameter fluctuations.
  • Sump Tank with Return Pump: Sump Tank and Filtration systems are ususally hiding below the main takn in a cabinet. Return pump is then needed to get the filtered water back up to the main tank.
  • Filtration System: A high-quality filtration system is essential to remove waste and maintain water quality.
  • Lighting: Adequate lighting supports the growth of corals and enhances the visual appeal of the aquarium.
  • Heater and Thermometer: Maintain a stable temperature around 27.7°C (82°F) to mimic natural tropical environment.
  • Protein Skimmer: Helps remove organic compounds before they decompose, improving water quality.
  • Top-off System: Water will evaporate from your system. This system tops the water level and prevents salinity fluctuations.
  • Powerheads/Wavemakers: Ensure proper water circulation to distribute nutrients and oxygen.
  • Refractometer: Measures the salinity of the water, a critical parameter for marine life.

The articles in this section will help you understand the functions of each sub system and select the one best suited for your needs.

5. Setting Up Your Aquarium

You got all the equipment ready, lets put it all together!

Add RODI water and salt, start all the systems and make sure everything works well.

Precise water volume

You will need to know the exact water volume of your tank, for salt required and future dosing. I always start by adding water and salt immediately after the equipment. Then add the live rock, removing water that the rock is displacing. By measuring the excess water you get the exact volume of water in the tank and the system.

6. Cycling the Tank

Establish beneficial bacteria to break down harmful ammonia and nitrites into less toxic nitrates.

Tank cycling typically takes 4–6 weeks. Patience is the key during this period!

Use test kits to monitor ammonia, nitrite, and nitrate level.

6. Introducing Fish and Invertebrates

Make sure to research compatibility to prevent aggression and ensure a peaceful community.

Don’t forget the Clean Up Crew: Invertebrates like snails and hermit crabs help control algae and clean up detritus.

Introducing Coral

Now it gets exciting for many, corals make your aquarium stand out.

But it is much harder to keep corals happy. So once you are comfortable with fish and live rock, start slowly with species suitable for beginners. Our article on soft corals provides insights into easy-to-care-for varieties that can add vibrant colors to your aquarium.

Where to start as a beginner to saltwater aquariums

When looking at setting up a saltwater aquarium, I would highly recommend researching as much as possible before actually purchasing a tank.  After all, knowledge is power!  It will  help at any stage whether you’re researching what first coral to buy or what reef safe fish would be good to start off with.  

As I too was once a beginner, I found it difficult finding all the right information in one place.  My aim is to make it easier for anyone looking to set up a marine aquarium. 

I have tried to include as much information as possible such as whether or not it’s hard looking after a saltwater tank.  Perhaps you have owned a tropical fish tank in the past?  I explain the differences in how a saltwater tank differs from a freshwater tank.  In order to run a successful marine aquarium you will also need to know about tank cycling, aka, the nitrogen cycle.  Do you know what a CUC is?  I’ll share all!
