is there a silicon that I can use whilst there is water in the tank?

I ran out of filament over the weekend and got more in today 2 more pieces to go and it should all be printed

Here's a pic of the front complete just printing the last 2 pieces for the side but done the bottom one.
I'm not bothered by the joins as coraline will cover it.

Well it's in. I broke loads of my plates whilst rescaping but that should all grow back together.

I ended up just using gorilla glue gel like I would for frags. Took 2 big bottles.

I only use PETG tho wouldn't try anything else.

I've been exclusively using ABS for a long time now.

Nice to know ABS also works well. However iirc petg is more resistant to ozone and UV. Not that I'm using ozone.
I only really do stuff for my own tank.
