crappy...
I lost 5 large feeders yesterday too, I had put them into my outdoor 100 something gallon pond. I added some blocks around the edge making it taller to thwart racoon invasions, well the base sand I used for the blocks was super fine, and some of it got into the water(ok alot of it did...), I did a ~50% water change, but that stuff killed EVERYTHING in the pond but the plants(I hope). drained, cleaned and refilled yesterday...just before my 90 gallon broke(see my post in this section...)
Had to sit through a choir concert yesterday to boot, just not a good day all around...
