a inch for distance your lamp intensity is 127mw/cm2
the formula is

Intensity X exposure time = Mircowatt second/cm2

i use a 15 watt bulb at 1 inch (127 mw/cm2) so 15 x 127 = 1905 mw/cm2.
A 15 second burst will kill just about every thing on the chart.
i have used it on every thing (no chemicals just water and uv)for 3 batches now. I have not had any contamination. Total Cost for set up has been 25 dollars.

I use a polished stainless tube UV water purifier as it reflects back vs the cheaper PVC UV systems on the market..
Check under "Garden Pond Solutions"
Trojan Max UV is a whole house system, not cheap vs a stainless Koi pond unit.

Have you had your water tested?

This is their address but you may have to try different ways to open their forum.
I used a larger than needed UV lamp system due to the fact it runs 24/7 for the Koi pond as well the UV lamp slowly dies reducing it's UV output. It kills the alage plus anything else in the water provided it's flow is set not to the maximum by the units manufacture. It will sterilize the water.
I use well water to brew with plus for the Koi fish leaving out the chemicals that can kill the fish. I replace my element every 8-10 months, for brewing it should last many lifetimes, reduced when used for house water. This I would add an hour meter to it if for house use and change out when it's hours of use are used up. Stay away from those plastic "El Cheapo's" trust me on this one. The internal stainless reflecting surface as well the quartz tube over the UV lamp should be kept clean for maximum function of the UV unit.
