I have a 48 litre tank with an interpet internal power filter (PF1) that has been matured for about 2 months now (although I have a slight nitrite issue - but that's not the point of this.)
I have another, much smaller, tank with an elite stingray 5 filter that I am attempting to mature with a fishless cycle. I was wondering if I could put this filter into my bigger tank (along with the existing filter) and if this would mature it for me without causing any problems for the fish in my 48 litre?
I've been attempting to mature this filter for well over a week and have only just thought of putting it into my bigger tank

because the filter I first got for it was so incredibly noisy and so I bought the stingray. I also thought the tank was a good deal, but it came with no heater so I had to buy that too. I know fish keeping's expensive and I shouldn't moan because it's for the welfare of my fishies - it's just annoying when you're a pretty broke student with no job.
