    Good day all

    I have just finished installing our new tank. its 1800x600x650 and been meaning to ask if a UV light is essential for the tank? the tank is a mixed reef. LR fish and really wanna have an amazing collection of corals. running Pacific sun LED's which on their own make the whole tank awesome

    looking at a Phillips FLT8 55W sterilizer and wanna hear if its a must, nice to have or a waste to have.

    thanks

    I think it's just a nice to have(if that even) and definitely not a must in my opinion.

    it would be one of those tube lights that the water feeds through to deal with parasites.

    I have been running one in all my tanks.
    It keeps your redox levels up, algae levels down and kills most of the bacteria in the water including good ones, so you will need to add on a regular basis.

    Have it connected to my overflow so anything in the water going to my sump gets zapped. :thumbup:

    Ultra Zap units work just as well as the expensive marine ones.

    Agree with @WarrenElvis, lots of very good scientific info. Got the above quote from the article.


    Also speak to @Quintin, he uses UV on his quarintine tanks, he'll also have a ton to share

    do you turn it on when you need it or only have it on in the evenings or when you need it.

    does it help with things like white spot etc?

    How do you know if it works, can you test for something?

    Hi there.
    You need to have a look at the life-cycle of the ich parasite for this.
    At one stage of the life cycle the parasite is free swimming and in the water of the tank.
    I would guess it could help by zapping them as they pass through the light unit but have no idea.

    I dont use it for this but then again I have not had ich in my tank now for almost 2 years... so there may be some truth to the myths...

    You need to have an ORP probe to test for Redox levels.

    Nope, I run mine 24/7 and change the bulb in it every 6 - 8 months.
    Open it up once a month to clean the bulb inside.

    The one I have is way over rated for my tank and is the same size I use in my pond outside...
    It is the big 55W Ultra Zap unit that is suppose to handle volumes of up to 55000L :whistling: but I always believed in overkill.

    Same goes for my skimmer.
    Running the JNS Shark 5 rated for 750 Gallons (2855 litres) on a 1000L system. :whistling:

    just read that artificial. what i gathered is that its recommended but when using things like stability etc its best to turn off for a day. dosing things like fuel etc would the vits and minerals etc get destroyed too

    Nope as vits and minerals are not living things like bacteria.
    UV light only kills bacteria and living things if the exposure to this light is high enough it does not change chemical compositions of elements.

    Also, dont look at an active UV light.
    The UV radiation is not seen by the human eye and will burn your cornea without you even knowing about it resulting in blindness.
