Help!! the bottom of my fish tank is...?

[Zoo tycoon gal]

the water in the the bottom to inches of my fish tank has gone a white/merky colour? My tank has been set up for just under a year now. It is 15 gallon. When i first set it up i cycled it. Any ideas what this could be??

its probably algae, u can jus siphon it out.
it could be from overfeeding your fish.
and the leftovers fall to the bottom and create algae.
so maybe try watch you fish while they eat.
to change the amount u feed them.

Try a gravel vacuum (if you haven't already).
