In your calculation nc_nutcase, what were the flow rates on your setup with UV?

Since flow rates is one of the key elements in setting up a proper UV sterilized tank.

The less flow rate the more contact time with the water through the UV sterilizer = better filtration

1W of UV strength per 10 US gal...
At 10 US GPH per 1 W of UV strength...


I do think a 9W light will be large enough for your 72 Gal bowfront... the trick is only flowing 90 gph through it... 90 gph isn't very much...
 
I've been out of the hobby for awhile and am just getting started again, but couldn't you kill two birds with one stone (polish & trap parasites) by using a good diatom filter?
 
I use UV on all my tanks, as I find they make a really big difference with water clarity/algae and also fish health. I live in the UK so our brands are probably different but anyway..
TMC Vecton range is really good, has a bulb traffic light system to tell you when to change the bulb (3 colours) and the new bulbs are not expensive.
 
I actualy have four of that UV filter already. Here in the UK they are branded under Fish 'R' Fun.

Pros: Have their own powerhead
Work very well

Cons: Small sponge filter clogs fast (but easily cleaned)
They go in the tank and look really bad.
When the bulb needs replacing you are basicly changing half the product and it is not cheap.

If you have an external canister filter then I would not use one of these. If you have an internal or HOB then yes I would.

I just ordered one for my 112g, only 24w instead of 9w

I have the 24w version of it, and agree with all the pros and cons listed above. The small sponge filter is especially annoying, but all in all it works well.
 
Couldn't you just take out the sponge? it's not like i need more filtration of that sort, i'm only interested in the UV for cheap
 
If you take the sponge out then the inside will get covered in poop, this would block the light and making the UV useless. The water should be as clean as possible so the the light can penetrate the water effectively.

The vecton models have a quartz sleeve that need regular cleaning, and it is recommended to be placed after the canister filter.
 
Never thought about installing it in with a canister filter but wouldnt a caniser filter flow to fast or inhibit flow? I have an ehiem 2224 pro-series?

I just read this statement about the Eheim 2224's output - "The pump output is 185 gallons per hour with the filter circulation of about 135 gallons per hour."

My recommendation is to use 1W per 10 gph...

Therefore I would syuggest to use a 15W or larger light inline after this canister...
