Seperate pump for UV or use ext Filter

[Les Johnstone]

Hi all,

Just setting up my tank again after a wipe out a few months ago. Got myself
a UV this time. Is it OK to put it in line with the ext filter or will it
reduce the flow rate to much, should I put the UV on its own filter? The ext
filter is 1000lph on my 300l tank.

Thanks for any help

It depends on the pump in the filter, line length etc. Why not try it and
see if it works. Measure the flow you get with the UV filter in line, and
check against the specs for the filter and the UV unit. If it drops
significantly below the recommended flow rate, you will need a separate
pump.

I did the same and put one in after a big wipeout, and operated it for
several months. I switched it off a few months ago, and all in the tank is
fine. Mine is in line with my chiller on a small (1000 l/hr) powerhead and
it is OK.

If you want to kill bacteria [bad and good] that is floating about your
current, you will need to set it up in a slow flow. It much more effective
when it have longer contact time. I recommend not to use UV unless you
really have a bad bacteria out-break.
