A few of you may have already seen the video of my tank I posted a while ago (link below) it is a 200l tank with about 30 fish altogether, plenty of ocean rock, a Fluval 405 external filter, couple of heaters etc

Every week I do two 40% water changes vacuuming what subtrate I can access every time, my nitrite and ammonia, as you would expect, are both ZERO but my nitrate remains constantly high, very high in fact. I have experimented by doing 4 water changes per week for a couple of weeks, feeding less but nothing seems to make a difference!
The fish seem very happy, it is a very lively tank without too much aggression, they get fed twice per day and all eat very well so should I be bothered by this, if I should be what can I do to reduce this level?
Thanks for reading.
