I know a lot of our tank set ups are alike and I was wondering what the service intervals you guys are doing on your big sump set ups. I have a little worry over here with an ammonia spike that I can't seem to get to Go away. I have a weird intuition that my submerged ceramics have become choked or clogged and are causing a major clog in the filtration process. Anyone else ever experience this?i have a 3 cuft or so reactor in a 44 gallon trash can along with 60-70 lbs of submerged ceramics in my sump,Mechanical is 100 micron socks. 100+Gpd drip. Not to extreme on stock levels 4 juvie Rays ranging from 7-10 inches.I feed moderately twice a day to keep ammonia spikes down. I noticed my fire eel "scratching" herself on the bottom of the tank tonight so I tested water and it showed positive for ammonia. Any clues or input would be much appreciated.
