Any updates? I had the opposite problem. I ordered plants in December and the heat pack was cold and next to the top of the box, but the bottom of the box had space that was open to the cold and all the plants were exposed to the hole/space. Upon receipt the plants were cold. The plants eventually ...

I wouldn't chance it. If you can smell it, they're going to shed stuff into the water. Whether it's harmless or not, who knows? How much are sponges, and how much are your fish worth?

Several years ago, we took over a maintenance account for a tank that had been ... creatively installed. (That's a polite way to say the morons who designed this thing had no business installing tanks anywhere). It used a sump, and the return was just, plop, at the bottom, through a bulkhead, tossin...

Is there a place to see this without enduring an hour and a half of video?
