I just bought a used Rena XP2 filter and i was wondering how i should clean the pads/filters inside the canister? I want to clean everything just in case the last person had any diseases or parasites in their tank. Whats the best way to get the foam/mesh filters clean and sterile? The filter has the black bio stars in it, is it ok to rinse them and reuse them or do they wear out over time? Also, is there a way to tell the age of my XP2? I've read a few post about the motors wearing out which results in a less of water flow.
On a side note - I got this filter with a setup i bought off craigslist today. I got a 75G tank with a Rena XP2, Marineland stealth heater, Whisper 60 or 100 air pump, moonlight, thermometer, and some chemicals + food for $100.
