Now take any decorations you may have placed in the tank, so all you have are the small gravel at the bottom, this will allow you to get any dirt that those decorations may have been covering up. Now if you do not have a gravel cleaner you are going to have to roll up your sleeves and get your hands wet. You will need to stir up the gravel to get the dirt that has settled between the gravel into the water, and start removing the water into the bucket with the hose. Do not throw out the water you will still need it to clean the filters.
If you have a gravel cleaner, push the plastic tube into the gravel until it hits the bottom of the tank, then start a siphon into the bucket, every second or 2 move the gravel cleaner over an inch or 2 and repeat this process until either you have removed 15 percent of the tanks water of you have cleaned all the gravel.
