I need some advice. I have been using some old calcium reactor that looks like Reef Octopus 140. It looks like top cover is missing some small part that I guess is there to prevent CO2 gas to go out with the water exiting reactor.
I can probably make that part out of PVC. But I wonder what is the material that cover is made of. And what kind of glue should I use to attach PVC part to it.
