Piscine;4806051; said:Got to home depot....Get a roll of thick painters plastic and drape it over all of the tanks. bunch the bottom up and use tape to keep the plastic tight around the bottom of the stand. Leave the filters running, but no air pumps....Turn off all ceiling fans, air conditioners, heaters, and anything else that moves air. Fog, spray or whatever....When you come back, leave the tanks covered for at least the rest of the day so no residual particles can get in.
Remember to remove all of your fish stuff from the house... nets, buckets, hoses, pumps, extra decorations, ALL OF IT.
I've done this many times when I had the town house in Oklahomo.. You will need to wipe down any surfaces where fish food prep goes on, and anything that you might touch while messing with your tanks. Its a tedious process, but its worth it when you have such a ridiculous amount of money tied up in tanks as I do.......
Hope this helps....I've been through it a lot and know how much of a pita it is. I have never lost a fish with this method.
You can get a 3 pack of 12x25 plastics sheets for like 4 bux....
