Hey there.....I was cleaning the gravel and doing a partial water change(because the water is so cloudy) and I noticed that lots of little flecks of rock were coming up in the siphon. They were too heavy to get siphoned out, but they were there. Could the gravel be disintegrating? Could this be the cause of my cloudy water? My tank has been cycled for several months.....all the levels are good - absolutely the same as always - but I can hardly see the back of the tank because of the cloudiness. The only thing that changed was that I had read that I had too much gravel in my tank, so I took some out.Then the water clouded up and has gotten worse from there on out.If it is the gravel causing this.....if I replace my gravel, will that do something to my cycle? I also added some carbon in the filter (Aqua Clear filter) to help with the "dirt/soil" odor that annoys me so much - I've read that that smell is actually a good thing...but the tank is in my room and it drives me nuts! Oh yeah....it's a 10 gallon tank with 5 small neon tetras, 2 bronze corys and 1 Red Wag Platy. Thanks a bunch! J.
