Hey all. I’m in desperate need of answers. My 75 gal reef tank has 8.0+ of ammonia. Stocked with 2 clowns, a royal gramma, and a goby/ pistol shrimp pair. It also has a few different soft corals. This tank has been established for years. A few months back, our city flushed their system with chloramine and my RO was not prepared for that. It killed off a good amount of bacteria (I assume) because all of my tanks had small amounts of ammonia for a few weeks after. Most of them have cycled it out by now though. We then had an ozone machine installed to combat the chloramine. I’ve also been adding bacteria every so often trying to rebuild whatever may have been lost.
Everything was testing fine as of Saturday 2/24. Yesterday all my corals were closed up and sulking. Royal gramma is clearly suffering. But everything is accounted for. It tested 8.0 ammonia (API) and 6.1 (fluval). Highest amount for both tests. I’m at a loss. I did a large water change yesterday and added a little prime and macrobacter 7. Came in this morning, still tested 8.0 and 6.1. I added a sponge and live rock from another tank into the sump with a little more prime and bacteria. I moved all fish and corals to a QT tank. Any ideas on how this could have happened? I've never seen anything like this.
