Children (anyone for that matter) can drown in less than 2" of water.
This grid won't make the pond safe for your child. If they crawl out
there or slip and end up face down, you have to immediately remedy the
situation. Because of that, you need to be supervising the child
around the pond anyway, and therefore I think the grid is unnecessary.
If possible, it would be better replaced by a gate or locked area that
the child can't get past on their own.

In many of these things I'm pretty much dependent on what my landscape
gardner has planned; he's already got the materials, but hasn't
finished the installation yet. I still have no idea what his safety
grid really looks like (fine meshed or huge gaps? sturdy enough?).

As I understand it the grid will be just below the water surface at
around 1 cm depth (1/2"), so should be fairly effective as a safety
device. We don't intend to let our toddler run wild in the garden
while we are going for a snooze, so he won't be unsupervised but even
for a 2 years old there is still a difference between stepping on the
grid (and being scolded) and descending into the big blue ;-)
