  1. So I'm still a novice but I noticed in watching videos of so many fish rooms and stores that many experienced aquarists drill all of their tanks. I understand the basic concept of a sump for single large tanks but I'm wondering about these systems with so many smaller tanks rigged together. Why do they do this and what's the benefit? Where does the water flow to, and how much of it needs to drain? Does this prevent the need for a regular water change in those tanks? Maybe dumb questions but I'm super curious about this.
  2. This is the process I used for drilling my next display tank. Its a 90 gallon tank with 1/4" inch thick glass. I'm drilling to install bulkheads to attach a canister filter too. Drilling a tank isn't as scary as you think if you've never done it before. You just have to go slow and have confidence, once you start there is no going back. It is more difficult and more likely to break on thinner glass, 1/8" or less. The tools I used were: Power drill. I think a two speed drill is best. Used on the lowest setting so you can't go too fast. Drill guide. I like this one with the suction cup. It held really well and has a port to attach a water line too. Squeeze bottle & aquarium airline. The bottle is from Dollar Tree, while not water tight, a thick wrapping of Teflon tape around the threads solves that. I found the Marina blue airline fit onto the nipple of the drill guide the easiest and onto the squeeze bottle. Some flat scrapes of wood and toolbox drawer liner Glass drill bit (obviously). I used a 35mm bit for a 3/4" bulkhead. I didn't want to do it outside with a hose because it was cold and snowing out at the time. I drilled it in my kitchen without making a mess at all. I used the flat scrapes of wood to wedge inside the tank as a brace when drilling. It helps contain everything once you get through the glass and maybe helps prevent some chip out. I used the liner against the glass to prevent the wood from slipping and wedged the piece between them to hold it tight. Go time. I wrapped a towel around the guide to contain the glass dust slurry. I had someone help by squeezing the bottle at a steady rate while I was drilling. I used the lowest speed and set the drill's clutch to the drill setting. Use both hands to hold the drill and keep it as straight as possible. Don't push too hard, especially on thinner glass, hold the drill tight and push down lightly, let the drill bit do the work. It takes time to get through thick glass, just go slow. You'll feel less resistance as you get closer to punching through, ease up on the pressure at that point until you're all the way through. Once you're through the hard part is over, except getting the plug of glass out the bit. Prying with a screwdriver in the slots gets it out. Removing the guide I found very little mess. Easy clean up. You can see the toolbox liner twisted and caught the bit as it punched through. I think that is actually beneficial, like a soft stop/landing for the process. I re-positioned the setup exactly the same and drilled a second hole, also successful.
