Yeah, that's the rub. There are limits to wattage of home UVs, but not to the flow. It just whips on by the effective UV...although the sellers may not mention that. I did a lot of research before I bought my old lost 1, including several inlines.

I guess you can find extremes in aquarium pumps and UV units that don't work, but I can't imagine you having a pump on a 110 that has a bigger output as a small pond pump that does like 2000 gal p/h. You can clean that water with a 11 or 13 watt just fine. If the flow is still too high, it can be easily reduced with a bigger hose on the outlet. I have used them both in ponds and aquaria, they work fine.

A number of years back when I first began keeping altum angels I decided to get a small UV unit for use in setting up their tank and then for the first few weeks after they arrived. I had no clue about UV in terms of what I needed to know to have an effective setup. I founf this site which is a commercial site, but the owner has a lot of really food info on UV. It had formulas for haw to select the right wattage and low rates.

I am nit suggesting one shop there or not, what I do think is you will learn more about how to use UV properly/effectively there: https://www.americanaquariumproducts.com/AquariumUVSterilization.html#categories
Be warned there is a ton of information on this topic on that site, to read it all will take many hours, but to gain a good working knowledge takes less time.

Well, dang, I thought I knew what part I needed & consulted with a "real" plumbing supply place. But NO, there's another missing piece! At least now I have a better idea...but it's a small wattage UV, maybe not enough for my 110g...still thinking...
