Ok....now that the crisis has been averted for now, I will tell you what I did.
Right now I have a 55 with all my fish, all 8 of them, all my inverts, all my corals. I have a 45 Gallon trash can that I use for water mixing holding all my LR, except for a bunch of pieces in the 55, with a heater and a pump. I have the 20 x-tra high holding all the sand.
I'm still not sure if it is the plastic trim on the bottom, which is cracked, or if it is the stand that is bad. So in the morning i'm going to have to order a new 180 and finish emptying the 3 inches of water and rest of the sand. Then take the 180 off and see if the stand is still ok. Some quick checks on the outside of the stand with a T-Square, show the stand is still perfectly square.
I have my RO running filling into another trash can and my neighbor, who is also a reefer, bringing over another tomorrow.
Once I get the new tank, hopefully the smae one so I can just reconnect the plumbing I have.....I'll fill it with enough water to cover the rock, put the rock in, then the sand. I figure with the amount of rock I have, it should be fully cycled in 48-72 hours. And of course I will be completely cleaning the sand with freshwater before I put it back in the tank.
Well crisis averted for now....tomorrow is another day
And luvmyreef.....thanks for asking, but i'm back to 100%....Tamiflu is a miracle drug!!
Eric.....it's not the floors....the stand is on the concrete floor in my basement.
