Tank crash

mistb2002 · Apr 17, 2021

Hi my 90gallon tank crashed after a 25% water change. New to the hobby with corals only. This is the 10th time my tank crashed. Before I had fish only and it was a nitrate spike. This time I decided to start off with lps and soft corals (mushrooms, torches, Kenya tree, favias and scans). I used R/O water not sure what went wrong. Any advice would help?

10th crash! I don’t think nitrate can spike although nitrite can make it appear so. Your gonna have to describe how you make your water in detail, how you check salinity, how you mix it, what salt, where does the RO come from, pic of your tank etc etc etc.
BTW, Welcome

Welcome!

Sorry for your losses. Like posts #2 & #3, more info please. Details of 'crash' and details on water parameters before and after crash. 10th crash sounds perhaps go slower. That's a lot of corals for someone self describing as 'new' - Glad you are hanging in there and still asking questions!
