Water Volume with silica sand?

Basicly i am trying to calculate meds and am wondering. do i take the mesurements from above the substrate , silica sand, or do i take it from the base of the tank? I would think that the silica sand would take up alot of the volume of the water. not to mention the stones and pot plants...

 

You'd do the following....

L (cm) x B(cm) x H(cm)
(Use your height measurement from the bottom of the substrate to the level of the water)

Divide by 1000
Subtract 10% of your answer for water displacement due to substrate, plants etc.

I've never had a problem doing it this way

Don't forget that if you have sensitive fish such as loaches in the tank that you should use half dose usually.

 

Multiply by 1000
less 10%

 

Divide by 1000
subtract 10%

 

my bad
lol
was thinking l * b * h in metres

cms is kinda hard to work with in larger tanks

 

No problem, just didn't want anyone getting all confused and WAY over dosing

 

LOL

dosing bottles would have to be much larger

 

They'd have to be HUGE Imagine our water bills

 

If I dose Anti Stress meds according to this calculation, I would land up with "Jamaican" fish...
