Hi Everybody! I bought this piece of property and although NOT on my bucket list, the property came with a koi pond. I have come to love my fish, but now the pump isn't working. I don't know anything about water features. I was told by the previous owner how to run the pump through the paces every week or so in winter and every few days in summer. The water is rather murky, but clears up once I clean the filters and run the pump. This morning it was fine but now the pump isn't working and the waterfall that runs into the pond has stopped running . From what I can tell it is a Hayward Vari Flo SX Valve filtration system with a Baldor Artesian pump APM-344 HP .25 Iit's all Greek to me!) There aren't any pond specialists in my area and I don't relish the thought of staying awake all night giving the fish mouth-to-mouth recessitation measures. PLEASE, what can I do until I can call someone from out of town or buy a new system and hook it up? Should I run down and buy a pump and stick the tube in the water to keep it aerated? I have about twenty koi, the pond is about 5 x 4 and maybe 4 ft deep...any suggestions?
