When I started out keeping corals around 2004 German aquarists were the leaders in terms of their technical approach to SPS keeping and the number of tanks with amazing growth and coloration although some of the corals would really brown out lower on the branches much like a lot of the early ORA Acropora like the Miami Orchid which was tough to color up. They had Tropic Marin and Korallenzucht providing high quality products and their own approach to the best reef supplements like amino acids, beneficial bacteria, iodine, trace elements. That Pooh’s Extra is good stuff. Anyhow, it was essentially the “Old School” approach of low nutrient, regular feeding phyto & zooplankton and the supplements like the aminos and vitamins. They added a lot of tech like reactors and probes and controllers to it as well. There was an emphasis on maintaining pH levels. Now, you can’t shake a stick at those German Reefs pre 2000 and I don’t imagine anyone would claim they were not getting accurate test readings on their own tanks or that they weren’t running very low nutrient systems on the best looking corals. A lot of people committed to the Zeovit system, but it was pretty expensive and fairly complicated, but the goals were the same. Low nutrient systems with extremely clear water, quality foods and complete major, minor and trace elements, vitamins and amino acids. There was never a mention of Nitrate and Phosphate levels or ratio until the balancing act of carbon dosing came along in the form of vodka and it works without a doubt by manipulating the bacterial po

When I started keeping corals in the 1990s the Berlin method was all the rage. Zero phosphate and nitrates was the goal though pretty much unachievable with the technology. Dosing phosphate and nitrates was one of the hardest things for me to do.
