    Is there anybody here that runs UV 24/7? I would like to know if this can be done and what the effects are of doing so.

    I run a 16w 24/7, not too sure if it does anything though, as can be seen by my previous "algae farm", although that was due to other circumstances. I can't say I have noticed any beneficial or non-beneficial occurrences happening in my tank, I have millions of pods etc. in my refugium and DSB so they are not being affected by it.

    a uv is said to kill bacteria as well as the beneficial bacteria.its better to run it for 8 hours a day.ive also heared that fish become immune to it,and when its switched off,they break out with whitespots

    I used to run mine 24/7, but haven't run it for a few months now and cant see any visible difference.

    UV `sterilizers` are not great at sterilizing at all, speed at which water moves past the bulb as well as the proximity or how close the water is to the bulb is very NB. The output of a UV bulb is hugely diminished within 6 months.
    Viper, they kill bacteria fairly well which may have been the reason you had an algae farm in the first place as it doesn`t kill algae spores well at all.

    I have never seen the need to use an UV steriliser. As Midasblennie says the pass rate in almost all instances is too rapid. I also see some members who in the past ran UV and now don't use it havn't seen a difference!

    So does this mean that the UV kills the bacteria possibly good but leaves the algea spores untouched. Which can cause a bigger reaction as there are no bacteria to consume algea or nutrients possibly. I am not sure if I am talking nonsense, please correct me.

    Thanx Ian

    Ian i believe each tank is different but yes this could be a reality with uv as algal spores usually have a thicker more impenetrable cell wall as opposed to bacteria, whether good or bad.

    i run a uv unit on my nano ,water is clearer, skimmer works better, corals happier than when i didnt for a six month period. uv tends to kill the reproductive cycle in unicellular organisms so that they cannot reproduce
