Hello everyone! I am a regular reader of the forum. As I am setting up a 900-liter marine aquarium, I have a question about when the tank will mature. (I have been involved with marine aquariums since 1999, but I have only set it up twice and don't remember how everything went.) I filled it with osmosis water, added AquaMedic salt, and poured in JBL additive for a quick start. I measured the pH at 8.00, calcium at 300 (I added calcium from a SERA bottle). Nitrates and nitrites are at zero. Everything seems to be normal. I added 150 liters of water from an old aquarium and the next day I started adding live rock. By the evening, everything that was on the rocks, so to speak, died. Did I start adding too early (it has been 3 days since filling)?
