Struggle Last Week

We had a struggle last week with the lab tank.  After the filter rupture, I didn't think it could get much worse.  Well, we had an automatic feeder malfunction over the Valentine's weekend, and dumped the entire canister of food.  After coming back to sky-high nitrates and ammonia levels, we did a major tank sweep and clean, and by Wednesday we had the water back to acceptable levels.  We did lose 2 fish out of that tank, but it appears they actually got stuck to the new filter intakes.  We still are considering moving all fish to the room tank and doing a complete water change, but don't think it's necessary at this time.
