  1. I have mine in a 1/2 gallon mason jar. I just top off with ro/di. I tried clado, Java ferns, and other brackish tolerant plants, none of them lasted for me. Only the green algae growing on the substrate has lasted.

    Gas exchange won't be a problem. The lid is nowhere near a perfect seal. It's just enough to keep evaporation down. 

    If the lid is keeping evaporation down, it is also limiting gas exchange. This means the difference in keeping them alive for a year or two vs. keeping them going for up to twenty years. I’ve had mine for six years.

  3. I got another way to put a hole in that pipe. Make a ceramic plug that closely fits the ID of the pipe. The top of the plug is cut on a 45. Place thermite in the void created by the angle cut in the top of the plug. Wrap the thermite section in foil so it stays put for the ride down. You’ll have a length of magnesium wire in the thermite to ignite it with wires and a power source up top. Lower the whole thing down into the pipe and let it rip. 

    Probably want to do a test run on a section of similar pipe to get the mass of thermite and ceramic plug geometry right.

  4. Is this a riddle, or a real project? Maybe if you could tell us what he is trying to do it would be easier to come up with a solution.

    I don't see any way to cut holes in a 4" steel pipe 13' deep from the inside. How big do the holes need to be?

    Super sketchy, but the only way I can think you would be able to do this would be to lower a cutting torch into the pipe, you would have to rig it up so the blowback wouldn't burn the torch or the lines, only way I can think of other than a hand grenade, lol.
