Water TEmp Question
I live in zone 9b, and my water temp in the winter only gets into the low
50's. Is it necessary at that temp to turn my waterfall off? I have a bottom drain where my external pump sucks the water from. Thanks, Lisa -- o_o_o_o /| ,[_____], |ŻŻŻL --O|||||||O- ()_)Ż()_) ŻŻŻŻŻ )_) Thanks, Ted |

Freezing should not be a problem for you and the extra oxygen created should be beneficial to the fish. deanna |

Water TEmp Question
We leave ours on all the time. Even in winter when it does freeze. No
problem at 50!

Water TEmp Question
BV,
I can empirically measure the temp differences at surface level with a digital (very accurate) temp sensor, and do the same at the bottom (6 to 7 ft) I've been doing this for 6 months now, and the maximum difference I've seen is 0.2 degrees... Of course, "wind-chill" may play a bigger role in winter, so covering up will surely help. Also, emperically (when talking about koi, there's always a difference) it has been found that if in summer the total digestive organs take about 18 % of a koi's body weight, after 3 to 4 months without feeding (and filtering) that goes down to 3% (). This is also the reason why the mortality rate of koi that have not been fed for a long time is so high in spring. They have been consuming their own fat (which also contains the toxins that somehow got into the pond), are very hungry, but just can't digest the food that they can catch and eating actually gives them less energy (they have to build up their organs again) than not eating (and they are already weakened from not eating/sulking at the bottom) Finally, you can emperically measure (again, talking koi) the difference in growth rates between feeding or not feeding. Problem is, you can't really feed them at temps lower than say 7°C, so you are kinda stuck with heating the pond. Not arguing mind you, and we should always distinguish between koi and more "native" fish. It can be argued that japanese Koi are a subtropical (or even tropical) fish, quite different from our native carp species (these evolved via selection to harsher and longer winters) Bear in mind that my fish have survived 3 winters without any feeding/filtration, so it's not a black/white thing, but there are very good arguments for keeping your pond/filter going 24/7/12.

Does mother nature turn off her waterfalls when the temperature hits 50? :-). Mine run all year, the small amount of heat from the pump and the warmer water from the bottom of the pond keep a small area of surface open.

Water TEmp Question
But BV after only a year can you really say, "I have not seen
empirical evidence supporting either argument." ? ;o) What has been found is that those in colder zones 7 and less that keep their ponds running full blast all winter have had fish deaths in the spring to early summer. Some folks think that they've had no problems because the fish didn't die during the winter, when the proof of the pudding is having ALL fish survive by summer.... crossing successfully over aeromonas alley. ~ jan On Fri, 7 Nov 2003 23:02:50 -0500, "BenignVanilla" It seems that this is a hotly contested topic.

And, do all of mother nature's fish survive the winter? No. ~ jan

I have a bottom drain where my external pump sucks the water from. ================= I shut off the big pumps (I have 2 ponds) that run the show in summer. In winter I leave a smaller 250 gph pump running in a corner of each pond to keep an opening in the ice, if any. I'm in zone 7 but most winters here are not that severe. They're too high and away from the deepest areas to mix the water levels. The fish all just hang out at the deepest spot all winter. -- Carol..... Don't go for looks; they can deceive.
