when the temp of teh water out of the tap is the same as the water in the pond.
usually, pulling that much out it is a better idea to drain the pond, move the fish
and do a thorough cleanup. OTOH, I see no reason to remove the elodea. it
oxygenates in winter and certainly pulls ammonia out of the water. Ingrid

The oxygenating weed in my 1500 gallon pond is really taking over now. (I
think it's Canadian pondweed, Elodea.) When is a good time to remove some of
it? It's all rooted in the mulm at the bottom of the pond so it really
messes the water up when it's pulled out. How much should be in there
anyway? I don't have much plant life in there at the moment, just a couple
of waterlillies.
Thanks
