Which Turbo-Twist to be paired with my Rena Filstar XP3? On my 55 Gallon tank? (I also have a Emperor 400 on the tank, but no real way to hook that up to a UV sterilizer.

If you know of another brand of UV Sterilizer that is better/cheaper/whatever feel free to pipe in.

Hi,
XP3 has 350 gph output. According to Paul, 12x 36watt can handle up to 290 gph to kill parasite. So you need a better one to kill parasite. At that point I am not sure what to suggest . Here is a good link for UV by Paul

Let's us know what do you decide?

Okay, I did some research and it looks like none of coralifes products are rated properly for my Rena Filstar XP3 at 350 GPH flow rate.

I did however find this

http://www.aquaultraviolet.com/uvsizingchart.php

and per that chart the Classic 25W is the best UV Sterilizer for me. (It should kill parasites at that flow rate)

Has anyone had any experience with this product? or this company? Does it look like I am reading the chart correctly?

Thanx

Rayston

Hi Ray,
Can you tell me how do you calculate please? I am looking for one also. Thanks.
Fred

Per this thread

http://forum.marinedepot.com/Topic33995-4-1.aspx

90,000 µw/cm²

is the industry standard for killing parasites and per this chart

http://www.aquaultraviolet.com/uvsizingchart.php

The Classic 25W will provide that at up to 400 GPH.

I am still trying to find some more solid documentation that that is the right calculation. I will post here if I find it.

Thanx

Rayston

Thanks Ray,
Thanks for your input. I am sorry to say that the posting of link to other forum is prohibited in this site. I am afraid, Mod will erase this...

that post is okay guys, its not a goldfish forum

From what I have gathered from acquaintances with marine aquariums who routinely use uv sterilizers, it is wisest to put the uv sterilizer on a pump independant from a filter so that the pump can be sized specificially for the sterilizer.

make sense... thanks for info..
for whom doesn't care for electricity bill

Fred, I know, I know... and from one who actually thrives on "simplicity", one more gadget sticking into my aquarium is a pain. haha. But from all I have read, there is a fine line between a UV sterilizer being very efffective and being effectively, obsolete, based on having the correct flow/optimal contact time. I asked around on the forums and didn't get any concrete answers about how to fanagle my filter set up to accomodate a UV sterilizer. So, I went to some of the [fairly] local marine aquarium stores and asked to see how the UV sterilizers were set up on their display aquariums. Lo and behold! Even on an aquarium as small as a 40 gallon, the UV sterilizers were given their own pumps. And the water was pristine in these aquariums. One fella' I spoke to, told me that if not for his UV sterilizer, he'd have sold his aquarium years ago, because he ws just about "Beaten" by ich and algae before he got the UV. So, it must be worth both the extra $$ in electricity and the extra tubing and electrical cords to contend with.

i had a 15w pentair aquastep installed with the XP3, but recently installed 25w goldfishconnection.com UVS. its a power-horse!
