UV clarifier lights, but stopped working anyway
I have a 40 watt UV clarifier hooked up to one of the gravity-fed
outflows from my filter. The pond is approximately 4000 gallons. For the first month of owning the thing the device gradually made the pond clearer and clearer, then last weekend it got so clear that I could see the bottom of the pond which is at about 4' in depth. I was very happy with this, and even commented to several people how it was great to own a product that claims to solve a big problem and it actually works. I work with computer software so I've grown very skeptical of promises since in the computer world things fail far more often than they work, so when this clarifier resulted in water that was this clear I was just amazed. Then Murphy's Law kicked in. In a matter of maybe 3 days the water clouded back up to a point that's nearly as bad as the days before the clarifier when in. Has anyone ever heard of something like this happening? I can't imagine alge ever being able to build a defense to intense UV-C radiation, so I don't think this is an example of the alge building a resistance to the light. So what the hell went wrong? Around the time that the alge returned I cleaned the filter, cleaned the pump, and put the pump into a new protective housing. Here are some thing that have happened in that time that somehow may play a part in this stupidity: 1) During the process of cleaning off the pump and putting it into a new housing, I forgot to turn off the UV light. Could being on for about a half hour to 45 minutes without any waterflow cause it to become damaged? I can see from the clarifier's glowing housing rings that the light is still on. 2) After cleaning the pump, its output increased dramatically. I had one of the filter's 4 gravity outflows intentionally disabled, and the filter began overflowing so I restored that 4th outflow. I thought that may have resulted in less water flowing through the UV but since the total amount of water pumped is higher plenty of water should still be going through the UV. Since the total amount of alge was near nill anyway, the alge can't reproduce much so reduced waterflow shouldn't hurt anyway. 3) The temp last week was a few degrees warmer than in previous weeks, and the sun is getting more direct. |

What's the make of the UV ? 40 watts can handle a lot of flow generaly. You sure you are dealing w/ algae... got a microscope... it is easy to tell if they are living organisms v. silt. jay Mon May 29, 2006 In article .com, scs0 wrote: I have a 40 watt UV clarifier hooked up to one of the gravity-fed outflows from my filter.

UV clarifier lights, but stopped working anyway (Koi lo been midnight bathing again)
Yep, yet another open and shut case of CArol Gulley aka koi-lo sneaking ntoyur pond and using it as a bath tub. She can polute the most pristine waters overnight when she washes that stank off her fat assed body of hers, and if she drags along her bots and sock puppets it can actually turn the water to a thick slime....... If you can figure a way of keeping carol gulley aka koi lo out of the pond yur problems will be solved.
