Having the house painted. The painters are pressure washing the house with bleach solution which is totally necessary. The worst part of the area needing to be pressure washed and painted is the covered walkway over the pond (of course!) We have draped the pond and waterfall with a huge 4ml plastic sheet which is laid on poles and fixed so that any water will run off around the outside of the concreted edges. I have turned off the aerator so that fumes are not being pumped through the water. I have my Ammo Lock handy and am considering a prophylactic dose (will consult with manufacturer). I really can't deal with losing any more fish after our post-spawn debacle. Our painter is super careful and respectful of our property, plants included, so maybe what we have done is overkill, but would rather have it that way than have another tragedy. When your fish are older than your grandchildren and have names it is worrisome!
