Something I read a long time ago about a commercial FHM pond was they used waxed cardboard from butcher meat boxes for the FHM to spawn on. The waxed cardboard was free (they must have had a source), would float for the season, then sink and be gone for the winter.

Not saying it was good or bad as I have never tried it. Just something that I read.

My initial pallets sunk after about a year. My solution was to slide a couple strips of 2" foam insulation (I had surplus scraps) inside the pallet and held in place with a couple screws. These have lasted going on 5 years but I think I am going to need to pull them this spring. The nails are rusting out and they are starting to come apart. One already has.
