Water temp question
While some of the folks up North are still wondering if they can feed their
fish yet, my water temp is in the mid-80's. The air temp is threatening to reach the 90's this week. The pond only gets full sun from about 11-4 o'clock (at this time of year), so I guess I need to make some kind of sun shade to shield the pond. The shade cloth I was looking at is rated by "UV Protection"; in other words, it will shield 50%, 80% and 100% UV. I can shade the pond without bothering the plants (which are all in the waterfall area, not the pond where the fish are - which is plantless). Therefore, total (100%) blockage of UV will not hurt my plant life. But which is best for the fish? Should I go for the density of the 100%? Also, which has the most influence on the water temp: direct sun or air temp? Thanks for your input. -- Lee B. See my Zone 9 a/b ponds at: http://community.webshots.com/user/dragnp |

Water temp question
Lee,
I think direct sun acts as a solar water heater and the thinner the water layer over the liner, the more heat that you would expect from the sun. The biggest factor would be the wet bulb temperature. The wet bulb temperature is also referred to as the dew point. If the pond temperature is warmer than the dew point, then it will evaporate like a cup of steaming coffee and evaporation equals cooling. If the pond temperature is cooler than the dew point, then you will get condensation from the air, and the pond will warm toward that dew point temperature. Mad will have higher temperatures than you do, but I would bet that her pond will stay quite a bit cooler than yours. -- RichToyBox http://www.geocities.com/richtoybox/pondintro.html "Lee Brouillet" wrote in message ...

Water temp question
RTB, we're talking Sunny Florida here. The dew point is usually enormously
high. Mad has higher day-temps than I do (out there in the desert), but she also has cooler nights. Last night, it went all the way down to a chilly 76 degrees (voice dripping in sarcasam), from a high of 90. When I got home last night, the water temp was 84; this morning it was 80. I have to try *some*thing to cool it down a bit! Any ideas? Lee "RichToyBox" wrote in message news:HCAta.741748$3D1.408386@sccrnsc01...

Water temp question
lee, you're right. in the desert we're really hot during the day (air temp
today 90ºF right now) but cooler water temps and cooler at night. the water temp right now is 70ºF. this morning before the sun came up the air temp was in the 60s. mad -- "Health nuts are going to feel stupid someday, lying in hospitals dying of nothing".

Water temp question
Lee,
Waterfalls would increase evaporation and give you the most cooling that you could get naturally. But with the high dew points, you won't be able to get that much cooling. The only other way that I know to get the temperature down would be by artificial means, kind of reverse what I do in the winter (called heating). Cooling by some form of heat exchanger to an air conditioner, or water chiller might work, but it would be expensive, and I don't know if it would be absolutely necessary. By August my pond temperatures reach close to 90, and the only side effect that I have seen is the fish being more active and more hungry. -- RichToyBox http://www.geocities.com/richtoybox/pondintro.html "Lee Brouillet" wrote in message ...

Water temp question
My fish eat 365 days a year. I find that if they are active, they eat, and
I have not found any problems at high temperatures. I have seen people say not to feed them at high temperatures, but I have not noticed that they are not hungry. I don't know where the rule came from, and if I can't find a good explanation, or come up with some plausible reason, I ignore the rule. In warm water, the fish tend to be at least as active, and burn more calories, so where I feed twice a day in the winter, (pond heated to near 70) I increase the feeding to 3 times a day when I can turn off the heaters, and from about June to November feed 4 times a day. The portion size is the same at all feedings. -- RichToyBox http://www.geocities.com/richtoybox/pondintro.html "Gregory Young" wrote in message t... Lee - A chiller could be used, but they are expensive to purchase and run (have one for my reef tank). The fish will survive without one, as long as there is good aeration (as the oxygen carrying capacity of water, poor as it is compared to air, decreases with rising temperature.) Rich - I have always stopped feeding my Koi when the averaged water temp. hits 85 degrees. Do you feed them above this? If so, have you noted any problems??

Water temp question
Is this plausible? The bio-bugs don't work as well at temps over 85F,
therefore feeding the fish when water temps are this high could be detrimental to your water quality.... and you know me, it's all about keeping water quality at its best. ;o) ~ jan On Sat, 10 May 2003 01:19:04 GMT, "RichToyBox" wrote: My fish eat 365 days a year.

Water temp question
I don't know. During the summer, I never register any ammonia or nitrites.
Right now, because of a big increase in stocking, I am running a trace of nitrites, and when spawning occurs, I will see major nitrites. But in summer, the pond does not show any. -- RichToyBox http://www.geocities.com/richtoybox/pondintro.html "~ jan" wrote in message ... Is this plausible?
