My Filter Has Died

[Realtree]

Bought a secondhand tank recently with an external fluval 405 (thought I'd got a bargain)
Unfortunatel yeserday the fluval died
Thought at first it needed a new impeller but found it was grooved inside the impeller housing - LFS with a smile informed me it was dead
as i have major plans and fish in situ I had to buy a new 405
Problem is
I have transferred the media from the old filter to the new and carried on
I have tested the water parameters tonight and the readings are as follows
ammonia 0.25
nitrite 0
nitrate 40

Tank is 180L and is occupied by 1 x angel fish 4" and 7/8 adult size apple snails.
Have done a 30% water change just now.
what reasons do you think the results are like this ?? and what do you recommend ??
Do these results suggest I am going through another cycle ?
cheers Mark

Id say you lost a bit of bacteria that was on the filter housing, just do water changes and all will be well in a couple of days.

I actually used the old cannister but fitted the new motor head to it
I did though clean the media with tank water as it was rather clogged so you think all will be well sooner rather than later ??

By the sound of it id say its just a mini cycle and should be over in a couple of days.

Thanx for putting my mind at ease
