So this weekend i went to the BAR frag swap, i picked up 16 frags (got some from swap and @Kremis brought me some). I had to drive 2ish hours to get there and 2 ish hours back so the coral ect. was in containers for 2-3 hours as i also went to a LFS and got something to eat. they looked fine when i was acclimating and dipping them. However when i woke up 5 of them were dead (mostly stony ones, 1 mushroom) and a few are dying right now. I also got a clown fish and coral beauty from the LFS. When i woke up i did a 30% water change, i have a 40 breeder but it only holds about 30g because of rock and sand ect. This is the parameters of the night i got the coral and fish. Salinity: 1.025 ALK: 10 CA: ~500 didn't test others Mornings parameters (after water change): Salinity: 1.026 Nitrate: ~1 Phosphate: ~0 ALK: 12 These are my first corals, i had 1 clown fish and no coral in the tank before adding the things above. The only thing that is really kinda "wrong" with the parameters is the alkalinity. Does anyone know what is happening ?
