I have a biomaster 250 on my 150 lt tank it is a well built filter built like a tank. Bought it july 2017.After 7 months it would leak every time I took it apart to clean it would leak say one hour later managed to sort it by lubricating the seal . Any way cleaned it 2 weeks ago no problems came down this morning to get some water 230am water all over the floor and tank below half way mark. I have a apare eheim professional 4 plus 600 but way too big for that tank so got all the media out and ramed it into my fluval 406 all I could do is use a little fluval internal filter i had in my other tank by the time I finished cleaning up it was 430 am .Managed to get a eheim professional 4 plus 250 with a 15% disount' out of pocket but happy with the discount.
Dont know if I will get a mini cycle so will have to keep a close watch it
