UV or not

Actually Pszemol, you left out a lot of important detail about how to
properly do a scientific study.

You also need to do the following.

Make sure the fish are of the exact same age.
Make sure the fish are of the exact same size.
Make sure the fish are of the exact same mas.
Water of the same exact temp +- .00001 degree.
Tank size of the exact gallons
Tank size of the exact dimensions.
Rock, sand, gravel of the exact same mas.
Rock, sand, gravel of the exact same size
Position in the room of the exact same location.
Sound in the tanks to be the exact same.
Food measured out to the .00001 kilograms.
Lighting measured daily to make sure each tank is getting exactly the
same amount.
At least 10 tanks of the control.
At least 10 tanks of the test.

2 sets of 10 is way to small a sampling to be of any statistical
significance. A proper study would use several thousand tanks in each group.

And it really does not matter if you have tanks for 25 years or 2 months.
Scientific method is much more important in judging how UV affects ich.

Observation is the single most important tool in the scientific method, and, in
most sciences, it is the only tool. Nearly everything we know about this world
has been learned purely by observation.

I suppose you regard the fact that the Earth revolves around the Sun as
"anegdotal evidence or wishfull thinking?"

If you torture the data long enough, eventually it will confess
to anything.

The point is that to make a valid observation you HAVE TO prepare
the subject of yout test properly. Without this, you basically confirm
your wishfull thinking...

I suppose you would agree with clerics chasing away Copernicus
for claiming their observation was wrong, and Sun does not
circle the Earth with the whole Universe... :-)))
Everybody who "observes" Sun and stars at night knows that
every celestial body runs around the Earth, the center of Universe :-)

Observation is not everything... you could conclude WRONGLY
from an observation, regardless how long you would observe.
