Mixing fresh and saltwater equipment???

[Buddyboy]

Hi All,

I would like to use an Aquaclear powerfilter on my 38G salt tank. I just removed it from my freshwater tank and would like to use it for extra flow, water polishing, etc. Just wondering how well I need to clean it before I use it in my salt tank? I have cleaned it with warm water and a sponge, but i'm sure there is still some freshwater grunge and algae still around. Is there anything in a freshwater tank that could harm my salt tank? Maybe i'm just being overly cautious?

Thanks for your thoughts!

Bud
