Particals in water

Question
It's like there is dust in water. I tried everything parasite, formaldahide, heat, cloudy water drops, complete water change, steralized everything, salt, antibiotic, malachate green.  Not in all of my aquariums. What next is to take a sample to fish store, unless you can help

Answer
Dear Joel,
Thank you for your question. The things you have tried - especially chemicals, complete water change, and salt - could stress the fish out.
The problem might be over feeding. If any fish food hits the bottom of the tank, you are giving them too much.
Another problem might be dirty glass. Particles of moss collect on the glass and with the right lighting, it might look like the particles are in the water.
Or it might be the chemicals themselves. I would guess overfeeding is the most likely prob lem.
