Removable glue for 3D PETG and Glass?

[kingyking888]

Hi,

Starting a Pico tank soon. I have 3D PETG print that I want to attach to the bottom of the aquarium glass. Still be able to easily remove should I not want to use it.

If I print a hollow base that covers the entire bottom of the tank and water fills it, will it still float?

Would hot glue gun work? How difficult to remove later from the glass bottom.

I will be adding coral frags so don't want it to come apart and 3d print floats to the top.

I don't plan on using any sand or rocks.

Thanks

so, you’re basically wanting to make a 3D reef structure? If so, silicone sealant would secure it to the bottom as long as you have a way for air to get out of the structure to keep it less buoyant. As long as you don’t don’t silicone it to the silicone on the seams of the tank, it should be relatively easy to remove.
