Our main pond has a bottom drain that goes to the berm ponds (veggie
filters). As the fish swim (esp. the koi) they stir the bottom and the
muck gets moved and pulled into the filter. The result is that the berm
ponds have the muck and the main pond is clean on the bottom. The berm
ponds have lots of plants to take out nutrients and slow the flow so
that the muck falls in the berm ponds. The berm bottom drains we open
annually in the late winter to get rid of the muck (drains out onto the
lawn). Mid-summer maintenance is nothing in particular except to pull
out bushels of plants and the veggie filters grow.

Can you run bottom drains? Makes life easier.

Hello all,

can anybody give us their ritual of mid summer maintenance to the pond.
I have a bio filter but I'm not sure if I should clean it since it is
established with good "bio".

Also does anybody have a good method of cleaning the inside of water
pump tubes that get coated with "guck" during these hot days.

Fish are happy and water is clear but there is more "sludge" at the
bottom and sides of the pond than there was in early summer.
Hottest summer on record here in southern Ontario !

Thanks !!
