The situation got worse! So id like some opinions here. This tank was a barebottom. Less than 30 gallons with 10 gallon sump. Had a lot of live rock but no sand anywhere. I kept this tank squeaky clean. I had it all, 100micron felt sock with a 200 micron mesh sock before it. A swc skimmer 160 which is rated for soo much more water. Brs reactor with the highest grade carbon (rox) and gfo. I would do weekly water changes of about 4 gallons. And i would syphon out all the detritus that would collect in one area. Literally all the crap was always in 2 coerners of my tank. Loved it. When the leak happened the tank was rendered disconnnected from all these filtrations. I put a few powerheads and a heater in main tank. Pointed the powerheads to surface. Next day (christmas eve) 2 chromis and a bicolor angel are dead. Water looks cloudy. Imediatly removed the remaining clowns to another tabk and used some water i had around and sump water. My gbta and rbta are fighting for their lives. I dont know what happened but i could only guesss.... Ive seen the cloudy water before.... Cyclle?
Could it be that i kept the tank too clean? And the tank depended on my filtrations vs the live rock? Could it be i never grew enough bacteria in my rck simply because the need wasnt there? And then all of a sudden i put the demands of the whole system on the rocks that werent ready?
