I've had my tank and fish for about 3 months now and in the past 3-4 weeks I've noticed that the filter keeps getting clogged up with a slimmy redish/brown substance and the water is staying cloudy despite 30% water changes. I'm suspecting that the slimmy redish/brown substance is just waterlogged food and that the cloudiness is due to water not being adequately filtered. But I really don't feel like I'm overfeeding. I've got 10 fish and feed them approximately 2 tsp of food per day (one in the morning, one at night).
Anybody have any advice?
