I have a 55 gal cichlid tank. For about a year I've had a cloudiness in my tank that no amount of cleaning can get rid of. I was doing a water change and when the water level went down, stuck on the glass of the tank were thousands of moving white specs. I took out my phone and zoomed in. They are tiny invertebrates, by the best of my research. I thought it might be infected in one of my fish, however I recently set up a brand new 10gal guppie tank. Using the water from my tap. A week later. The same cloudiness. Same problem, thousands of living white specs. Could this... issue be coming from my water source? And how do I solve it? Please help. My fish can't happily live like this.
