Looking for a UV for my new tank

[tecwzrd]

I was under the impression that the water traveled all around the light while twisting thus exposing more water to the UV light versus water only being exposed to one side of the light with the other models. But you are probably right, just a marketing ploy.

P.S. I’m the cook too

tec: The water does travel around the the light. My point is there are several ways the same exposure time could be created. If the water was simply pumped though a larger pipe with the light down the middle in a smaller pipe the exposure time should still be the same because the water flow speed would be much less. By putting The water in a small twisted tube the speed of the water has to increase to maintain the flow rate. I am not saying they do not work. I have one and like it. I am talking about physically moving (y) amount of water from point a to b in x amount of time. Water speed or the pipe diameter has to give. The results will always be the same.

I must confess , I cook also. I heard you say that you were going to run it one day every week. I run mine 24/7. What about the rest of you guys.

I get what your saying. In essence, assumimg that the water speed is the same, you could increase the dia of the pipe, which would increase the GPH, but the exposure time would still be the same.....

I read in the live aquaria catalog that flow rate rates of +300gph was enough to get rid of algea, but the flow rate would need to be 100-200gph to eliminate parasites. It would be more accurate if company's spoke of exposure time in terms of real time, and not a flow rate that could be vairable.....due to water speed, pipe dia etc..
