For the past few weeks my water has seemed unaturally cloudy. Now bear in mind that this picture was taken a few days after a water change, so it's not at it's worse. When it is I will post a new photo, but even now it still seems a little cloudy too me. It's not as bad as it was a few weeks before (after going through about three 50% water changes), I'm wondering if this is how it should look or something is definitely wrong. Does this look like average water clarity?

You say it has been this way for the "past few weeks" - is the tank only a few weeks old, or was the water previously clear and changed a few weeks ago?

cloudy water can be caused by numberous things obviously, most common is a bacterial bloom. this is very very common in a newly setup aquarium and can disappear and then reapper several times untill the tank matures. this is the benifital bacteria mulitplying (clody water) to accomidate change in the aquarium. when the water is clear the bacteria are no longer mulitplying at a high rate and are not in the water colum but attached to any surface in the aquarium. keep up with about a weekly water change 50% or so and keep a handle on feeding. it is also a good idea to test the water ph, ammonia nitrite and nitrate. a established aquarium will have 0 ammonia unless your tap has it in it.

That water looks like what my water looked like before. I had what I thought was clear water and then I found out that your supposed to have x2 filtration for a tank so I threw an extra AC70 on this 60 gallon and you can definately see the difference in the water quality.

If this is a new setup, it is possible that you did not clean the gravel well enough. If this is the case and it does not settle out, you will need many water changes or even a tear down to clean it out.

Alternatively, in newer tanks (or in cases of neglect or over feeding or sometimes just an abundance of organics in source water) a bacterial bloom of heterotrophic (decomposition) bacteria can produce cloudy water as the bacteria population explodes to process an abundance of dissolved organic compounds. This usually clears in a few days and is rarely an issue in established tanks.

Edit: Note that this (heterotrophic) bacteria has nothing to do with the bacteria that process/oxidize ammonia and nitrites (as these are different 'critters' altogether). However, these bacteria are an inevitable beneficial bacteria in decaying the organic matter.

aquarium has been setup for a couple of years and the water has only started looking this cloudy (on a regular basis) a few months ago back in December.

Kill the lights and suspend feeding and see if it clears up in a few days.

then adjust feeding and lighting so it stays clear.

This seems to be a bacterial bloom (which is basically harmless) but the answers to the questions asked in previous posts will help us sort out the probable reason.

There is one other option, and that is cloudy tap water; run a large jar of water from the tap and see if it is cloudy. I remember having very cloudy tanks for several days after each water change one year when very heavy rains washed minute sediment into the water reservoir lakes.
