Hi all. I'm back. I apologize for disappearing for long stretches, then returning with lots of questions!
Anyway, I "opened" my pond about a month ago after all of the ice had melted to find that all eight fish that were alive last fall made it through the winter! Unfortunately, there is no sign of my last remaining tadpole or one of the two frogs. The second frog never left the pond and, as a result, was belly up on the bottom. I assumed the frogs would leave on their own and find shelter for the winter, but I guess I was wrong?
I also cracked the hose between the pump and waterfall last fall during the winterizing process. I figured this was coming, as it was old and brittle. I'll need to replace it before I get that pump running.
All else looked great. Water was clear after I cleaned out the leaves and other debris. Plants have begun to grow. Fish are very active -- and much less timid, strangely -- than they were last year. Some are even looking bigger.
And then Monday night, when I got home from work, I noticed the water level had dropped by about 3 inches from Sunday. Then by yesterday morning, the water had dropped another few inches -- and as of last night, I had to unplug my fountain pump, which sits at about the half-way point in terms of pond depth. I've lost a good 12 inches of water since Sunday, and I'm at a loss -- frustrated beyond belief.
This will be the third or fourth time I've had a problem with this pond -- which, as I've mentioned before, was inherited from the previous owner of my house. I'm assuming the hole is the same one I've patched in the past, as it's the only hole I've ever had, and the pond retained water for a month or so before the leak. Not sure a new hole would just randomly show up at this point.
I'm not sure what to do right now.
- Go drastic and rip out the entire pre-formed liner, replacing it with a soft liner. I feel like I would have to alter the landscape, though, to slope the sides to get to maximum depth, whereas, right now the side walls are basically vertical with the pre-formed pond.
- Go mid-range and paint the entire interior of the pond with an expensive rubber paint that should seal the pond and reinforce it for the long haul.
- Go basic and try to patch it again, as I have in the past, but with more care and more time
Any help would be appreciated!
