The MacQuarium
Sunday, August 14th, 2011A little over a year ago, when I still worked for Mercer Law School, a student worker was cleaning out a faculty member’s storage closet. They stumbled across a vintage Macintosh Performa 200 (by vintage, I mean 1992). Thinking it belonged to the technology department, they brought it to us for disposal. I decided to keep it to see if it would work. It didn’t, but it was too cute to trash. I remembered seeing photos and stories on Instructables.com about people turning old computers into working aquariums and I knew that this would be my next project. I promptly took it home.
After some online research, I stumbled upon a great set of instructions by Andy Ihnatko. Like cleaning the insides out of a pumpkin, dismantling the computer required special tools and certain protruding portions of the case had to be removed as well. Between a Dremel and a hacksaw, I finally removed the portions of the computer necessary to build the aquarium. (My apologies for using “Mercer Law” and “hacksaw” in the same blog post.)
After getting the case like I wanted it, I cleaned the outside thoroughly. When the computer was found in the closet, it was covered in spilled Splenda. I also used black spray paint to give the insides a nice, new look. Some vintage macs have Steve Job’s signature engraved in the inside. This one, however, did not.
Next, I needed glass to build the actual tank. I went to Lowe’s and learned they only carry 1/8 inch glass, which wouldn’t support water. Home Depot had the same. Specialty glass shops online wanted big bucks to cut the glass. At this point, I lost motivation and put the case in the attic for over a year.
At my new job, I desperately needed some sort of decoration, etc. to personalize my office. Perhaps a conversation piece? One day while riding down Riverside, I discovered a glass shop about 3 blocks from the office. I printed out the dimensions I needed and took it in to see if they could do it. Not only could they do it, but it was only about $9.00. Score!
I came home and assembled the pieces using regular silicone and leak-proofed it with aquarium-safe silicone (which was difficult to find). I also constructed a wooden base to position the glass box on (and keep the electrical, etc. underneath).
Next, it was time to design the look of the aquarium. My friend/former boss Chris had an aquarium in his office at Mercer for several years and over that time I did a few different shots of the law school as the background for it. That background got rave reviews. Since I work in a beautiful building now, I thought that might be a good plan. I also love bubble bars and Mackenzie picked out some neon-colored gravel, which I bought against my better judgement.
I also needed a light to illuminate the tank, for visibility and to make the fish think its daylight inside. I wanted to go LED even though the price was a little steeper. I found a great LED light that can even be submerged if I ever decide to put it under the water line for about $20.00 on eBay.
Because changing the water would be difficult, I also needed a filter. I found an under-gravel filter online (powered by the same air pump that will generate the bubbles) that is supposedly perfect for small tanks. Since I plan to start with cheap goldfish, a heater/thermometer isn’t necessary. Of course, I can always add one later and go with a better filter.
Here’s the complete list of supplies:
Glass: 10.26 (also bought a second set, just in case — if you want it, let me know)
Silicone: 3.77
Aquarium-safe silicone: 7.41
Wood for the base (select pine): 6.84
LED light from eBay: 20.73
Under-gravel filter: 10.72 (shipping was more than the actual item)
Air pump, tubing, valve, gravel: 17.42
Fish catcher, food, and vacation feeders: 6.89
Distilled water: 1.21
Fish: 54 cents
Total cost: $85.79 (yikes!)
I went a bit over my $50.00 budget, but shipping killed me on a few items (filter, light) and I spent more to get better stuff on others (light, wood). You can purchase a similar sized aquarium kit at a local pet store for $25 or so, but it wouldn’t be nearly as cool.
I also bought a small table to sit it on for $8.00 at IKEA so that any leaks wouldn’t damage my office furniture, but I ended up not using it because it was too small.
I initially set the tank up on Friday to give the water a few days to circulate, I ran into a few problems. The air pump caused a loud vibration noise that was not conducive to a work environment. I also had issues with the gang valve leaking and ruining my background print. Currently, I have removed the bubble stone and I moved the pump to outside of the computer case. I set the filter up to run continuously, but put the LED light on a timer so that it simulates daylight for the fishies.
Today (Sunday), we added two goldfish from PetSmart: a regular orange one and a white one with an orange spot. Let’s hope they are still alive tomorrow when I get to work!
The photos above as well as the video below were taken with my iPhone. I forgot to take a camera! I’ll try to post more shots soon.
Hopefully I don’t get fired for having this at work. Nobody knows about it so far. Remember my motto: It’s better to ask forgiveness than permission!
