The last 9 months have been the best so far. I struggled to keep corals long term before that. The root cause was too little light. I’m now seeing consistent lps and sps growth.
No fancy equipment or effort. I put 15 ml of kh buffer in each day by hand and 10ml calcium a week. I might change a bit of water every other month maybe. I don’t even text the water anymore. And it’s going better than ever.
