I will be away for a month. The tall plants will be cut back and a net will be put over the pond to keep the leaves out. The pond has a circulating pump from the skimmer to the falls/stream and a pump feeding the skippy filter. Should I trun off both pumps and leave a bubbler in the pond? Will the fish be OK if the pumps are truned off and just leave the bubbler on? I guess they will be alright without being fed. The weather will be getting cold here be the middle of October.
