Pump recommendation

[oldfishman]

I have a JBJ 28 gallon that I want to add an additional pump for water flow at the recommendation from R2R contributors. I am looking at either the Koralia Nano 425 GPH or the Suicce 530 GPH Voyager Nano pump. Does anyone have experience with either of these pumps and can you make a recommendation for one over the other. I also would like to know how quite they are. I am open to other suggestions.

Never had a problem with a Sicce pump.
I just tossed a koralia 425 in the trash.
Used it for a month, then put it in storage.
Brought it out to use again and could not get it running.
