too much light?
 

Is it possible? I have read that more is always better but is there a limit
based on size of tank?

The reason I ask is that I am deciding on either a 250w or 400w halide and
the prices are comparable. I have a 36"x16"x17" 46 gallon. I'm building the
canopy myself so that isn't an issue.

400w on a 46 is probibly gona be NICE for a while i ran 400 on my 37T, ive even considered
going back to 400

problems of too much light are mainly heat related. once you get over heat, there is not
much else left

So if I went with the 400 should I build the canopy to have the light a
higher up to help on the heat or just build in some fans?

Wouldn't you have to concider the types of corals you will keep for making
the right purchase ? some need low light, some need strong some inbetween.

thats what rock ledges are for

and lets look at the question, its not a comparison between 20w and 400 its between 250
and 400, though its an assumption, its kinda safe to assume the OP wants light. the
difference between the two is not high light or low light, both are high light, one is
just better high lighting. as the OP said the prices are "comparable" so price isnt the
issue either.


so yes and no!

if your looking at using this to guage what you need, maybe or maybe not.

Most corals that do fine in low light also do fine in high light, but there are
a few that will not do well in the brighter light. But that's no reason to go
with lower lighting. Like the previous poster said "That's what ledges are
for". So don't short yourself on lighting.
