How long?

Kazzy

I just made a few sponge filters for two of my tanks and had to use hot glue on a few things. Wondering how long it has to 'cure' before putting it into my tank? Thanks!

about 20 minutes just to be sure it hardens hot glue is great!!!!!!

Kazzy

Oh wow, not long at all then. Well, it's cured then, I let it sit overnight. lol thanks!

isnt hot glue wax based and will slowly melt into your water?

hot glue is a no no, especially when aquarium safe silicon costs $4 from Menard's

SinCrisis

+1, its ~5 bucks at home depot for a tube of GE Silicon 1 which is aquarium safe as well..

i have used in my wifes tank for over a year with no issues at all .. no melting no leaching... its been fine...

Kazzy

Yeah I was under the impression it was safe. I've heard of lots of people using it especially to glue rocks together so they won't fall.

Go for it if you are confident then. Its just not something I would ever use or recommend. Glue does not say "aquarium-safe" on it anywhere does it?

Kazzy

Don't know if this makes any difference but it is non-toxic and I talked to some people that have used it for years with no ill effects whatsoever.
