Hi Warr - no - I would rather say to plumb the UV filter at the sump return pump's side...
I am not 100% sure on this, BUT I think personally that the UV filter just MIGHT affect you skimmer's ability.....
Also - the main idea of a UV sterilizer is to kill off any micro organisms that might be detrimental to the fishes' lives.... ie. bacteria's that might be harmful, or perhaps even fungal spores or something like marine ich spores...
The problem I have is the outlet pipes are bigger than the inlet pipes and the inlet pipes are the exact size of the UV unit.
Are you referring to inlet and outlet of skimmer in above quote? I think what Jacquesb was referring to was plumbing into your return pump pipe. It is critical to the efficiency of the UV that the water going thru the UV is as free of organics as possible to prevent shielding. You want as much stuff to be removed through skimming and settlement over DSB / cheato, before entering UV chamber.
Hi Warr - yes - preferably to the return plumbing.... What piping did you use for the return plumbing?
I use the clear piping. I am going have to change it to PVC
Why so?

just wondering guys, what is the effect of UV on marine algaes, i know the koi boys use UV alot for algae, would it kill the spores etc too? I assume one would only run UV over a period of problems as a corrective measure, not as a preventative measure all the time?
Sure, if the two are the right diameter. What type of fitting is on the UV?
Should be able to get one of those plastic "ejay" barb fittings with threaded side that would fitScrew on type. I will have to check if the diameters are the same.

Hi Crispin - NO - it does not kill macro algae spores, I believe. Due to the cellular structure being different to that of zooplancton/bacteria cells/marine ich spores(cells).
Plant cells have a cellulose cell structure, which cannot be easily be "broken down". Where as the "animal" type cells (zoa) have a very thin outer cell layer, keeping the "insides in".....
UV can break down the outer "skin" of the "animal"(zoa) cell, but not that of a plant-like cell-wall....
