uv questions
- Thread starter midnight
- Start date
just got everything hooked up.
my pond overflows into a 55 gallon drum,then a 200gph pump pumps from the drum to the uv sterilizer,then back into pond.
thanks for all the help everyone.
is the green water gone yet?

Point 1 if you leave the UV turned on 24/7 then you wont get hardly any film build up on the glass sleeve in the UV
The UV will kill the bacteria if left on 24/7 thats the whole point of the UV if you are getting film build up on the UV tube then you are getting bactiria back into the tank
it doesnt matter which is in and out thats why the UV is not marked with a in out or out

Always follow manufacturer's directions when posted, midnight you were right to ask when you didn't see the directions. Some units have a higher resistance to flow in one direction (restrictions created by parts design) vs the other or it can change the 'self-cleaning' function (water swirls around lamp).
Turning it on/off will limit it's effectiveness, in the beginning leave it on 24/7 till the green water is gone plus a couple of days. Then you can experiment cutting it off for a few hours a day for a week and watch the water clarity (actually pull a sample out in a clear glass and put a piece of white paper behind the glass as a reference).
Did you take any incriminating(embarassing) before pix

turn it off if you want but whats the point in having a UV if you are only turning it on when you have green water problems
leave it on all the time and the problems wont start in the 1st place
if their is no indication of in and out that means it doesnt matter or the unit would state it ifs a problem thats why we have left and right shoes so you know what foot to put them on
belive what advice you want but it needs to be turned on 24/7

its like a large mechanical filter....no need to run 24/7... but its not that you turn it on when you see problems...a larger unit can be turned on and off on a regular basis ( timer) and be completely effective
see "aquatic systems engineering" by p r escobal ibsn 1-888381-10-8
do you have any references about needing to run a uv 24/7 ???
thanks john

a UV for a tank sole putpose is not for green water
a UV for a ponds only use is for green water and nothing else thats why a pond UV is a waste of time for a tank
do your resurch
talk to the marine boys then come back
run it when you think you need it if you want but it wont be doing what its ment to
its your UV do with it as you want

if i wasnt clear in the prior post:
uv covers a wide range of wavelenghts determined by the specific bulb in the unit.... this is more important than whether you call the unit pond, fresh tank, or salt tank.
second... depending on the wattage and design of the unit and what you want to do with the uv....kill bacteria, kill algae or kill parisites etc ....will determine the flow rate.
third.... given a specific tank size and flow rate thru the uv...this determines how many hours on and how many hours off it needs to run....more running will not make a noticable difference in the water after this point.
hope this explains it better..........john
