Bonnie and Carol and all,
Thanks for the info. So the bio-bugs need 50 deg. or higher to survive.

## I'm sure some still do their job in colder water since I never had an
ammonia spike in spring or fall. I don't feed them at all if the water is
below 50 to 52F. I'm more concerned about them not digesting the food if
the water temp' drops overnight.

So I suppose that I should also hold off feeding my goldfish untill then
too,
correct? Would it be ok to just run the pump to get the falls and stream
running now (the air pump with bubblers are currently running) and I'll
just
put the lava rocks in when the weather is 50 deg. and/or over. Should I
use
last years rocks or use new ones?
Thanks,
-Pat

## I don't use lava rocks because they're too hard to clean. If you're
going to turn it on now you may as well add the filtering material of your
choice.
