    Tank Inhabitants— Corals: (Option to List)

    1. Mix of SPS, LPS, and soft coral.

    Who was responsible for getting you into the hobby?
    Diving was my great passion years before I got into the reefing hobby. It allowed me to see amazing aquatic life up close and aroused a desire to have my own part of the ocean at home.

    How long have you been doing this?
    I've been doing this for 20 years.

    How did you start?
    I bought a used, functioning aquarium. It was much cheaper than creating my own set, but after a time I realized that corals were not doing as great as I'd wanted. I started improvements, slowly changing into better equipment. All the time I looked for knowledge, reading, getting to know more people from the hobby and day by day I was becoming more aware of what I'm doing with my tank.

    When did you start this current (featured) tank?
    I created the featured tank 6 years ago, but about 3 years later lack of time made me change it to something less demanding.

    Who or what in the hobby most influences/inspires you?
    Nature of course! As I said, my passion for aquatic life stared with diving. Guess the beauty of the ocean will never cease to amaze me. As for inspiring reefers, I guess, I value my business partner Damian the most. For his amazing knowledge about corals and a strong will to share it even with less experienced reefers.

    Any good or bad surprises?
    I've mistaken Component 2+ bottle with AF Perfect Water, so basically I've changed my water 20 litres of KH solution... It was a disaster ending up with 40 dKH in my tank. After a few water changes everything came back to normal, but such a sudden KH raise was a shock for some corals.

    What are your future plans for improvement/upgrade of the tank?
    I'm happy with my current equipment, and I am not going to change it any time soon. I just want to keep the tank the way it is – healthy and thriving. As I said, lack of time is the thing that holds me back, so I have to stick to some less demanding corals. Though, I must admit, I'd really love to have some rare species of corals and surely one day my tank will get some new, exotic inhabitants.

    Any advice for others and especially beginners?
    Only patience and consequence can keep you going in this hobby! There's no one formula for a perfect tank, so you should never forget that all the fun is in constant reefing (with all ups and downs of your tank) not in reaching excellence.

    Final Thoughts?
    Passion is the key! Without a great feeling for diving and corals and without a strong desire to "keep some ocean at home" all the obstacles and my own mistakes would have made me quit the hobby a long time ago. Fortunately, I'm the one with the passion and a strong desire to share it with others.
