All is well, now I know why the call theses snails turbo .....they were quite busy last night. Later today we will do our weekly water change. Going to roll with no fish until mid July. Had a really sad experience...guy my husband works with was having a garage sale. Come to find out he is selling his 14 gal Bio cube with live rock, sand and critters...my husband wants larger, but says....let's get it for back up, quarantine or future fragging...we walk in and my heart sank. Silence, tank isn't running...over run with gunk. Starfish on the glass here and there.....there are what look like bugs in the water. We immediately start plugging in stuff... Nothing is working. The light switches in the hood are broken. I ask why it isn't running and he says he just unplugged it a month ago. How do people do that? I was so pissed off at this guy, there was no way I was buying anything from him.
