glue gun - hotmelt glue

is gluegun glue toxic to fish ....
I am moking a filter and need to glue some stuff befor i put
silicone(marine) ....

I take it your glueing plastic together? If so, I would not use
silicone in the end product. Silicone is not the best thing to stick
plastics together with.Get some MArine Goop at the local big box
builder supplies.. Silicone is long term effective on glass but sucks
overall on most pastics. And to answer your question, i do not know
for sure about hot melt glue but I seriously doubt it woud be
harmfull.

==========================
I used it to glue some shells together for a small tank without a problem.

Speaking as a chemist, most hotmelt glues would be perfectly safe.
However, I would ask, what type plastic are you making your filter from?

Perspex and two undergravel plates ...

The thing has two compartments one solid 2 filerplates and a solid bottom
and sides

the undergravel plates form a compartment between them and the water from
the tank go in the back compartment thus allowing the water to run through
some filterwool to get rid of the big stuff ...
the two pumps that feed the main tank delivers 300 gph each thus I have
about 500 gph coming through the "prefilter" which now sits in my sump. this
handles the flow nicely - will see what happens once it gets dirty and how
often I have to replace the wool ...
hopefully not often as the undergravel plates I used is 18" by 24" each
in the main tank I have a canister filer doing another 500 gph but as this
does not go through the sump that water is no problem

Since the stuff sits mostly below water with about 1" sticking out strength
is not really an issue it just had to hold
I ended up using hotmelt just to tack the stuff and silicone to "seal" it
all.
the end construction is very sturdy ... so it should hold.

OK, sounds like you did OK then. If you have any problems with the
bonds, I'd suggest using a light sanding of the areas where the hot melt
will adhere. That should really enhance adhesion.

I know from experience that the glue form a hot glue gun isn't going to
hold hard plastic together well at all. The slightest resistance will
break the bond.
Even scoring the plastic doesn't seem to help much.
I've tried too many times over the yrs with kids toys and other
household things that needed to be fixed, or crafty projects, etc.
I'd go with a glue made for the aquarium. You're going to get a better
bond.

Crazy glue will work just fine.

I would have thought that would most defiantly poison the fish

Su-er glue is not going to hurt a thing in a fish tank, be it fresh or
salt water. Its used all the time in sw setups. best bet on plastics
of unknown type is marine goop. Slightly abrade or scuff area where
you inted to apply glue for best results, or even play a flame on that
earea to deoxidize it is best, but just a thourough clenaing of parts
first and applying marine goop will be suffiicient in most cases. It
can be bought at big box stores like Lowes and HOme Depot.
