Thanks great postnc_nutcase;3232251; said:Read the manual about an AC 110 and it'll tell you that it can filter up to a 110 gal tank... then ask hobbyists with practical experience with them to find out what the real deal is
I have no clue what the Turbo Twist manual says... nor would I give it any credit...
After 5+ years of personal experience using multiple UV lights (including Turbo Twists) I've come up with a formula of 1 W per 10 US gallons... and 10 gph per 1 W of UV strength...
In other words for a 90 gal tank a 9W @ 90 gph... using a stronger light only gives you better protection... 18 W @ 180 gph...
Runner a bigger light than necessary or running it at a slower flow rate than necessary will not do any damage to the tank, the water quality nor the equipment. As long as the unit has some flow it will not be harmed. At some point you have to admit overkill is wasting money (initial investment & electrical consumption)...
As mentioned, the ‘good bacteria’ we want in our systems grows on surfaces. Provided the tank is cycled there is no risk to bacterial colonies when using a UV light… I do suggest suspending their use during cycling…
And my fish are fine lol although I bumped the flow to 120 gph roughly. I wish I could piece the jibberish together better but I can't really tell what you are trying to say...tcarswell;3233228; said:Thanks great post![]()
And FL2008 What the hell are you even talking about ? Theres no warning about the flow rateAnd my fish are fine lol although I bumped the flow to 120 gph roughly. I wish I could piece the jibberish together better but I can't really tell what you are trying to say...

Your not annoying in the least bit I am glad you could contribute and its a viable point. I just did not understand your post.FL2008;3234773; said:about that sorry for the word "warning" but what i mean is that on the guide of the UV, if you put below 150 GPH, the UV will kill your parasites, and you said now you are using with 120 GPH roughly, it's ok for that flow rate, that will make your water too clear and clean, the fish will get used to it, but have you ever think that when your UV is off or your water condition change, your fish will easy to get sick and disease ? like people always drink good water, and if they drink dirty water, will they get sick ?
do you turn your UV on 24/7 ?
sorry if i'm so annoying![]()
