Slider bar range in Manipulate?

I am building a manipulate out of a complicated differential equation with three time coefficients K1, k2, k3). I am having a problem with the third time coefficient (k3). My problem. I cannot figure out an appropriate value for the increment. Here is my code.

{{k3, 0.0000119, Style["k3", Blue, Bold, Medium]}, 0.00000010, 0.0000250, 0.0000000050, ControlType->Slider 

As written, my code places the slider bar knob in the middle of the range. Problem being, moving the slider does not move my graph. Not in the slightest degree. What am I doing wrong?

Thank you, sir. You are exactly correct. Have a nice New Year.

I think the effect of k3 is just too small when k3 itself is that small. If you increas the maximum of k3's range, you can start to see some effect. For example replace 0.0000250 with 0.0250 and re-evaluate the Manipulate. Now you can start to see effects when you use k3's slider.
