tell m what i am doing wrong.

1.2
tub is about half the size of a 10 gal tank laying on it's side.
drill holes all around, 2 every inch as big as a pencil
water bottle attached to side, very secure
hopper in top, thanks for instructions whoever you were
1-2 inches of aspen
industrial strength and size cardboard tubes
i clean every 7 to 10 days

very strong smell of amonia.
i use bottled water cause our tap water is wicked hard and tastes like crap.
all 3 are same age, 2 months i think.

my water bottle leaks a little. i find the aspen underneath is usually wet and stuck together for a few inches around the bottom of the bottle. it's the 3rd one i have bought and keep having that problem so i figure it's the rats making the mess. yes i bought a different one each time. had glass, plastic, plastic.

thanks
