I asked yesterday if you could help me find quiet external pomp. Since nobody have any suggestions i ask this way. I have external Gen-X pump. It is really noise <hmmmmmmm sound>. Do you know any brand witch is more silent? There is option that i change set up and put internal pump i my sump. Internal pumps are quieter probbably since they operate in water,right? No worries about heat, I have chiller. Any suggestions and brands? Thanks,please help!!!!
