Thanks Gordon. I have used zeovit for a few years, but it was too much work in my opinion. Especially during holidays there was, in my opinion, not enough room in the tank's balance to withstand small mistakes made by the persons who take care of my tank when I am on holiday.
I did switch back to the Berlin system, to add more stability to the system I did automate the dosing of the Balling Salts and trace elements (Grotech ABC is what I mainly use). To keep nutrients in balance I use some biopellets and a minor amount of iron-based phosphateremover. Next to this, water changes (I mainly use Tropic Marin salts and Reef crystals, every now and then some NSW from the coast here) do the trick.
Water quality, current and stability are the main factors, combined with good quality lighting of course. I don't mind if a certain value is a bit too high or too low, as long as that parameter is stable. As light I use Orphek Atlantiks since March this year, in more than 20 years reefkeeping this is the best light I have ever had. (having had multiple setups with combinations of T5, T8, HQI and led). Together with the Bubble King skimmer which I bought in February 2005, this is the piece of equipment which made the biggest positive change in my reefing carrier.
Good luck setting up your own tank, do you have a thread or pictures of your current tank?
