Glue Gun

[Dennis-Pir]

Anyone use a glue gun (as in a hot glue gun) to attach rocks or whatever to items to make a cave in their tank..? and if so? was there an adverse effects

I am thinking of doing a DIY PVC cave and covering it with rocks, going to use aquarium safe silicone, but want to use the glue gun to get the pre-lim stuff on...

Side note, is there a safe silicone you can buy from Home Depot that is ok to use in aquariums or can you only pick that up in your LFS?

I used a hot glue gun to make a cave out of slate.

It held well out of the water, but after 2 days in the water it came apart and didnt hold.

I would go with silicone even though it takes abit more time to dry

In my experience, hot glue didn't work at all for holding rocks together. Silicone does the job, but you have to kinda 'clamp it' or find a unique way to set it down while the silicone hardens.

I used "aquarium sealant" silicone to stick slate together and it works beautifully.

I used aquarium silicon to make a rock structure and it was kinda wobbly, a bit like me mind, but they never did come apart.

To my knowledge there isn't anything toxic in hot glue that we need worry about in our tanks. I've used it on a few piddly stuff before and have had no ill effects. But as others have said, it don't hold anything heavy worth a dang for more than a day or two at most.

GE silicone I for windows and doors is 'fish safe'. I've used it in many projects, sometimes in great quantities and had nothing bad happen from useing it. $3 a tube for this sure beats the $11+ for the 'aquarium silicone'.
