I helped my sister and her husband "winterize" their pond in WI. OMG, it was nothing but "I don't think that will work", and "I think that's going to freeze and break" and "the fish will get too cold if you keep the bubbler running" ... it went on and on! I drove 5 hours to "help" them, and then get argument each time I suggested what to do! In the end ... yep, I got my way, and the fountain/bubbler is the only thing running. Well, I wanted to keep the bog running, but my BIL was certain the line would freeze since it comes out of the water over the bog edge and back into the bog. I tried to convince him, as long as the water was running, it would not freeze, but he had nothing to do with that!
Does anyone have the Laguna Skimmer and Laguna big box Waterfall with filter pads? They thought they were going to seal off the front of the skimmer, and drain all the water! I suggested they just shut it off, pull the pump out (which the guy buried the electric cord, so all we could do was pull the pump, wrap it in a couple of bags, and leave it there, which is fine, it's empty of water ...) and lave the water in. Need to have something to hold it in place, or it will float and then blow away! So, now BIL is worried that the waterfall box, which is only sitting in about 4" of water (yep, about how deep the ice will be, my guess) is going to crack and break. I told them to call Laguna and find out what they say. But, IMO, if that waterfall filter box was up on a rock wall, buried in, there is NO WAY you could get the box out of there and bring it inside. I think they will be fine if they freeze, but didn't take ANY responsibility, told them to call and find out. I sure hope I'm right, cause I'm not spending another $100 and 10 hrs of driving to come help them again. Geesh ... if you don't know how your pond is put together, you deserve to have problems with it, and they WILL!!!
Oh, and my original suggestion was to keep EVERYTHING running. All lines are inside the pond or in the water, except from the skimmer to the waterfall (which is why I said good idea to shut them off). And, since they buried all the cords, they couldn't even bring the UV light inside! Had to take the bulb out of the casing, and leave the electric cord in a bag outside. I told her to unbury the cord next year, then just cover it with mulch so she can take it inside. "Oh no, I don't want any cords showing EVER!" Ok, then why did you ask me to come help you??? :banghead3:
