A good rule is to change 10 to 15 percent of the water each week. If your tank is heavily stocked, bump that up to 20 percent each week. A lightly stocked aquarium can maybe get by for two to four weeks, but this should be the maximum length of time between water changes.

What's the difference between 6z and z6

Airida [17]

Simple..

there is a major difference between 6z and $z^{6}$

6z means: 6 times z

and

$z^{6}$ means: z to the power of 6(z*z*z*z*z*z)

An example...

make z=2...plug n chug..

6z----> 6(2)=12
and
$z^{6}$ ---> $2^{6}$ =64

As you can see..there is a major difference.

Thus, your answer.
