I went to do a water change about 2 weeks ago and found ants swarmming around the top of the filter. I tried to drown them out by soaking the filter motor in a bucket of water for hours. I thought they were gone until I did a water change again over the weekend. I did the same over and it was amazing how many ants were in there. I have ant food traps near the filter, but nothing seems to work. How can I get rid of them with out poisoning my fish?
