Hello, I have top fin 30 waterfall filter on a 29G recently cycled tank. I added 3 juli cory fish in today (first fish in the tank) but didn't feed them yet so I don't think they will affect this. I was recently advised on here to wash my filter pad instead of changing it to prevent the tank from being uncycled. I washed the filter pad out in old tank water 4 days ago then put it back in. Two days later the red monitor appears again. So I washed it in the old tank water again more aggressively (swished back and forth rapidly and tried to rub stuff off with my hands). Now today I am getting the red signal again and the water in there is near the top again. Am I doing something wrong? I have not put any food in the tank in over a month since I got my ammonia in a bottle for cycling and did a 95% water change after cycling. In the past two days the filter has started making this mechanical sound that it usually only makes when I plug it back in before I put some water in there.
