DIY caves..

[Beau]

I am thinking of making some caves for my aquarium. I read how to make caves somewhere on the internet and it said to use a hot glue gun to glue the pebbles onto the pvc piping.

Has anyone tried this. Will the hot glue be toxic to my fish even after it has dried.??

Hi Beau,

I personally wouldn't use hot glue, I would use aquarium safe silicone.

I'll agree with Targaboy and add that many use superglue to adhere corals to rocks in SW tanks so I know that's not toxic. (and might be a little less messy)

And if you're using superglue, and you're extra creative and patient... you could even just glue rock upon rock and not need to use a PVC... just watch those fingers!!!

Yes the silicone is slow to cure at 24 hours but it is SAFE.

The hot glue is instant, but results of use unknown, it might be safe but I would not want to try it out on my fish until I was sure.

I have found that hot glue falls apart when exposed to water, not really good in a tank.
