UV sterilizer recommendations

[aglarond]

I ordered a turbotwist 18W and a HOT 250 magnum the other day, so I'm not dissing the twists in any way... lol

both players took 60 seconds to get on and off the field...
who is dirtiest?(exposed to UV)

Good analogy but higher energy light penetrates deeper into water than lower energy light. That's why blue light or actinic light is associated with coral growth, it's the only light that manages to penetrate down through the water. Ultraviolet light is even higher energy light than blue or purple light, penetrating even further into the water. A meter of water would absorb as little as 1% of the UV rays coming from the bulb. If the water is turbulent or as calm as a sunny day it really wouldn't change anything.

Change the mud in your analogy to the sunlight above the field and it makes more sense. All the players are getting the same amount of sun, no matter how they walk, because they are all on the field for the same amount of time.

If that was the case, then why don't we just put a UV tube in the hood and call it good?

If you want to eat crispy fried fish for dinner you could do that

UV light kills living organisms and that is why you cannot put it in the hood and forget it... it would kill your fish and give you cancer…

If the UV unit holds one gallon of water... and we pump 60 gallons per hour through it... we obviously have 1 gallon per minute flow rate, so the water spends one minute in the unit... It doesn’t matter if the water is spinning, flowing straight or doing acrobatics, it’s still in the housing exposed to UV light for one minute…

Without the fins there will be a more varied flow within the unit, meaning some water molecules may get pushed through in less than one minute, while others dwell for longer than one minute, but the overall average time a water molecule will spend in the unit is one minute.

Adding the fins will remove a very small amount of space that water would otherwise occupy, so by having fins it has a smaller water volume which means technically, the fins reduce dwell time…

As described above, the UV light will easily penetrate throughout the housing, unless the fins shadow some areas (shadowed areas will still get UV’ed because light reflects, but reflected light is not as strong).

I’m also not criticizing the Tubro Twist lights. I have several of them and I have continued to purchase them well after I realized the twist was just hype.

The football field analogies are very difficult to line up as a UV unit and a football filed have very little in common. This is a matter of volume… so it’s mathematics, not gym class…

lol you guys are getting carried away with the techinical stuff. if it works, then it works. what we need is photographic proof. this is my tank, 55g. BEFORE and AFTER. 3 days elapsed time. end of story

heck yeah!!

 

[Danger_Chicken]

Where did you get that...I want to put one on mine too once its hooked up.

I got mine from That Fish Place. Most fish stores carry them. I'd like to find one for 500-2500pgh.
