Beautiful tank Szymon.
The amazing colors shown here and on other European T5 lit tanks like Lunar's and Iwan's show us the true potential of T5s. They are particularly well suited to "tuning" the spectrum and providing a very even light coverage onto the corals.
IMO/IME, the large percentage of bulbs (60+%) that Szymon dedicates to the blue/actinic spectrum is the reason (along with excellent stable parameters and flow) that makes these corals glow. What this spectrum of lighting does is maximize fluorescence and this is what gives the jaw-dropping "pop" effect to these corals. Szymon also has the other parts of the spectrum present with his other bulbs as this is necessary for both growth and to avoid a "washed out" look.
Great job, definitely TOTM quality!
