So i finally got approval for a fish tank, no wait let me rephrase that I finally found a tank small enough for approval. Well that happened 5 weeks ago and its been standing in its place doing nothing while i ummmed and ahhhed as to the perfect setup and well. until last weekend I decided not to over complicate it. Maybe just a little. Thanks to Sumeshan and Nemo's Janitor I got some awesome equipment and all those old bits and pieces lying around at work got put to good use. The tank 1m X 0.5m X 0,5m Water level @ 0.450m It had a normal corner overflow which consumed a fair amount of space so I cut it out and built a skinny one covering the LHS. I also cut out the old stained clear silicone and resealed the tank with black silicone. And that's how it stood while i ummmed and ahhhed about the rest of it. Here is a pic of the tank Here is the new overflow.
