algae problem

So i got a bottle of 25% Glutaraldehyde and I'm looking to dose it in my 40 gallon tank. How many ml of Glutaraldehyde should I be using? Math is not one of my favorite subject.

Here is a handy calculator.

You just need to dilute from stock concentration to 1.5%. You can use m1v1 = m2v2 as a simple algebraic formula to solve it (or use the calculator...I like to verify everything myself as sometimes calculators can be wrong/make assumptions)
