Everything you need to know about setting up a tropical marine aquarium from tank size to equipment.

Due to advances in the marine hobby, it is now possible to keep fish and even corals in small tanks like the Fluval Sea Evo and other tanks of similar volume.

Water can look crystal clear yet still be deadly to fish and with reef tanks you have the complicated lives of corals and invertebrates and their needs to think about too.

Marine fish have evolved to take advantage of all the different types of food that are available in the ocean, so their foods need to be diverse.

Reef tanks take time to mature and within that time conditions may not necessarily be at their best for all inhabitants.

Marine aquariums are perfect for creating an impressive display of vibrant corals and beautiful fish in your home. While saltwater systems are more demanding than freshwater tanks, with the right planning and care, they can be incredibly rewarding.

In this guide, we’ll cover everything you need to know to get started, from choosing the right tank and equipment to stocking and caring for your new reef.

The oceans are unrivalled in their size and stability, and the corals we keep have evolved to that very, clean, pure, stable environment.

For the new reefkeeper, pH shouldn’t be made a priority. Once corals are added it is KH which has greater immediate importance because it drops quickly.

A pristine reef full of fish and corals looks idyllic, but alas many (very desirable,) fish species are there to eat corals or other fish and will do the same in the home aquarium.
