Uh huh, been there done that too. I was topping off the front puddle, while cutting grass. Got done with the front yard and headed to the back. Sat down to take a break on the swing, fired up the lawn mower and started working on the backyard. Then when I was done, went in to take a shower. Yup, the water reminded me. Lost about 5 goldies. Since then, I carry the declor with me when ever adding water. Even if I go in the house, the bottle stays with me where ever I go. If I sit down, I sit it in my lap. On the pc, its sitting in front of the monitor. Think you get the idea.
So far, that's the only time I've done it. That was about 4 years ago.
