Turbo Twist 3X

Hey everyone.

Does anyone know if the Turbo Twist 3x is a good enough UV sterilizer for my 72 gal? You may remember I'm the guy with the terrible green water problem and upon some of your advice, I'm springing for UV sterilizer.

I just don't want to waste money on a piece of garbage.

Any help would be greatly appreciated.

Max, I misread this....must be my dyslexia. For a 72 gal I would get one higher from the 3w, or the 9w....if it isn't too late, call them and get the next one up. I read it as a 27 gal not a 72 gal.

You have a 90 gal with the 9w no? The Turbo Twist 3x is a 9w. That should be fine for my 72 gal if it's good for your 90 gal. Unless I'm misunderstanding something here.

I agree. It's too small. I would contact the shipper and reject the shipment and then contact the place where you bought it from. Most companies will give you your money back.

UV's are suitable when water passes though them at a specific flow rate. There's a similar post here which I posted the following...

9 watt - 55 GPH to eliminate parasites, 121 GPH to eliminate algae, 253 to eliminate bacteria

18 watt - 110 GPH to eliminate parasites, 240 GPH to eliminate algae, 500 to eliminate bacteria

36 watt - 290 GPH to eliminate parasites, 680 GPH to eliminate algae, 1550 to eliminate bacteria

Even if the max GPH on the XP2 was between 200-250 GPH, the 18 watt would be sufficient enough to use to eliminate algae. Using a 9 watt, you would practically have to reduce the flow to almost half or less than the normal output, which lessens the effectiveness of the filter. You might as well just buy a small pump if you went with a 9 watt. Unfortunately, if you wanted to use the UV to eliminate parasites, even the 18 watt would not be sufficient, therefore, the 36 watt would best suit the needs. But as most of us use the UV to eliminate GW, then the 18 watt would best suit you. Although, if an event of a parasite outbreak, you may consider using a small pump to best utilize the UV.

With all this talk about GPH, I might look into buying one of the GPH flow meters, since I have an Eheim Pro II 2128, FilStar XP3, and Eheim Ecco 2236. Unfortunately, the flow meter only comes in a 3/4" fitting and my filters use either 5/8" or 1/2" tubing, so the flow meter may not be as accurate. There is a more accurate flow meter here, which allows me to use one for each tubing size, but at $100.00 (USD), it's not very practical at my income.
Basically, on your 72 gallon, you are probably running a filter that is producing about 250 gph (assuming), as you can see. If you connect the UV to your filter, the only thing you will probably eliminate is bacteria. The more time water lingers in the UV (dwell time), the better chance it has of eleminating smaller particles.

Of course, you can still use the 9 watt UV in conjuction with a small pump or powerhead that produces about 120 gph.

I'm using an Eheim 2213 which I thought was 150 gal and hr. With the Co2 diffuser at the end you would think it's getting slowed down even more. So would this be OK?

since you ordered it already, you can try it and if the green water doesn't go away just hook it up to a cheap Rio pump or something that has a lower flow rate.

A 2213 will have a slow enough current to kill off greenwater algae. I use an eheim 2235 (rated 180 gph) with my 9w TT and it works just fine. You'll be alright .

Max...so I didn't misread it from the start. the 3x is 9w... i thought 3x=3w hahahaha.....that is fine. It works on my 90 gal like a charm...3 days and bubeye. Your 2213 should be fine. It may slow things down a bit to have it in line, but it is awesome and you won't be disappointed!

18 should do it...do you mean plumb? I opt to keep it inline, and plug it in only when I need it.

Thanks everyone. I'm now wondering if the TT UV will slow things down too much as an inline device so that my CO2 diffuser doesn't work. So many worries... LOL
