UV sterilizer recommendations

[aglarond]

I suggest using a Magnum HOT w/ micron cartridge & a 9~10W UV… this Magnum canister is rated at 250 gph, but with the micron cartridge with a blue filter sock over it the actual flow rate is slowed to approx 100 gph (I use this exact combo on 3 different tanks).

Exactly what I needed to hear. I didn't get any BGJDs but at least I got some good advice.

How about that... your batting 500!!!

If there is anythign else I can let you down with or help you out with just let me know!

The volume of water the housing can hold will determine the dwell time... not the spinning motion. That's just TT's hype (although there's nothing wrong with the twisting motion).

With the TT its not the spinning motion but the fact that the twist create a longer path for the water around the bulb giving it more exposure time.

I have a 18w TT on my 220 dialed down to 100-140pgh (depending on my fluidized bed's mood - I love the FB but it's a pain in the butt) TT recommends 120gph to kill parasites. I added a $7 Tom's flow meter to mine, well worth it if you want to cut it back enough to kill parasites as well as algae.

Not really, if you were to remove the twists the water would stay in the chamber for the same amount of time.

Why? The flow rate into the unit and the flow rate out of the unit wouldn't change. That's determined by the pump. The volume of the chamber also wouldn't change. Those two properties are what determines the time the water stays inside the unit, not the path the water takes. Think about it. If anything, removing the twists would increase dwell time, because the twisty fins end up displacing their own volume in water.

With the twist tho, the water has a longer route to take from the inlet to the outlet giving it longer time around the bulb....at least thats what I think. Also if the chamber is too big some of the water on the outer edge of the chamber might not be close enough to the bulb for it to kill properly...maybe?

$7 Tom's flow meter

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

The benefit of the turbo twists is you can have the same length as much longer UV's in a smaller package due to the twists. Thats the only advantage it has.

Exactly.....more contact time.

No guys, if the twists weren't there it would just move more slowly through the entire unit, giving it the same amount of contact time. They really don't do anything.
