So, in 2016 we had the patio redone with pavers. The tourists who did the work (for the lack of a better term) partially emptied the pond at the time, and they sent their mortar specialist to smooth and redo the edges of the in-ground pond. The chemical products in the mortar caused contamination of the water and in a matter of days killed the dozen (relatively small) koi fish that lived there. We repopulated the pond with goldfish.
Fast forward years later and I am seeing cracks appear on the edges.
Is it time for a drastic solution like transfer the fish & plants elsewhere, empty the whole pond then fill it with liner, or wait and see until it gets worse? Any leak could potentially infiltrate below the pavers and create even more settlement problems etc.
I could drop the water level a bit to remain below the cracks, however in winter when it rains the water level will get somewhere up to 1" below this edge (the long edges are not even at the same exact elevation so the water reaches one long edge first).
That is the same edge where I am planning to lay my bog filter on top of the pavers, a rectangular basin which will contain about 1400 lbs of gravel and more for water. The load will be spread over 10 feet, but still...
Any thoughts?
