My 40 gallon tank

All-in-one system (AIO) with 40 gallons of water volume. The dimensions are a 60cm cube
Introduction
Hello everyone, I'm Justin, the new member here. I'm very happy to join this big family and look forward to learning a lot about marine aquarium knowledge here.

Let me introduce my marine tank. I set it up in December 2024. I chose an all-in-one integrated marine aquarium, 40 gallons, and it's a 60-centimeter cube tank.

I love this coral tank deeply. Since I got it, I've been learning relevant knowledge almost every day—how to keep marine fish, how to care for corals, how to establish a mature digestive system, how to treat fish diseases, how to sterilize and kill pests for corals, how to adjust the light spectrum, how to set the water flow, how to test water quality, and so on.

Fortunately, over these 9 months, my tank has been maturing continuously. Currently, both the fish and corals are growing healthily, becoming a dazzling scenery in my home.

I also welcome everyone's suggestions to help me keep this tank better.

Thank you!

Additional Aquarium Information

What do you think are the keys to your success in reefing?
Keep a positive attitude and don't add chemicals randomly. You need to fill the corals as soon as possible and let the corals dominate the system so that a stable system can be formed quickly.
