1) Pondzyme (i.e. pond bacteria mixes), Is there a problem if too much
is put into pond...does megadosing bacteria mix in the spring help
water clarity? Would it be dangerous?

2) How about pool type vacuum, that allows vacuuming the bottom
without draining the pond...that said I cannot see the bottom of the
pond.

Unfortunately I have no experience with either of those two topics, but others
have!
Also did you catch the answer about dead algae and UVs? I also don't run a UV.

I still recommend cleaning the pond as sludge does build up and a UV does
nothing for sludge. You can make a quick check by getting in, bending over
(brrr!) and seeing how much 'stuff' is down there ;-)
