Hi, we're having a problem with our pond, once every couple of months or so it empties. It's never completely emptied so our fish are ok, but its getting lower every time and we have no idea what's causing it. It does it at random, there's no pattern to hot days or dry periods, for a while it seemed to happen after heavy rain but I don't know if that's a real pattern or not.
The pond is roughly rectangular, wider at one end, it's about 10' long by 5' at the narrow end and 7' at the wide end, with a surface area of 60sqr', it's 4' deep at its deepest point, which is most of the bottom, with planting shelves. It's attached to a whole series of waterfalls, splashpools and streamways, but they're not running because we think there's a leak somewhere on the waterfall because when we run it we lose water so we don't run it all the time. There's a filter running in the pond at all times with a return coming in just above the water level to agitate the water and aerate it.
Please help, we're worried about our fish if this happens when we're not around to refill.
