D strikes again!!

So D decided to feed the fish yesterday morning. He ended up feeding them about half the can of food...needless to say the aquarium needed to be cleaned out. I mean it is not the fishes fault that he decided to not listen and feed them, why should they die?
This is what their water looked like in the entire aquarium. Very gross!

Back home! They love it. They can breathe again and it is clean, sparkling clean.
I found this while out curb shopping the evening...I am not sure what it is but it is cool. It was made by Lane but I can't look it up. There used to be some green felt type stuff inside the drawer. If you know what this is let me know. Thanks.
