Hi there, pretty new to all this, was given a little Aquastart 320 to play with and love it so much have upgraded to a 60 x 30 x 30 tank (60 litres? - what is the difference between our litres and US litres? 
)
Anyway I digress, I have 6 guppies, 2 cherry shrimp and a Golden Nugget Pleco that I want to put in it. It needs a good water flow for George the Pleco and was looking at the Aquael Internal UV filter 500, but wasn't sure about the UV bit. I don't seem to have any probs with algae in this little tank and thought it was needed for the shrimp and Pleco? Will it be a problem having UV for them?
