JBL Silent Pro 100:
Processing of the diaphragm pump well, the included accessories like air stone and back flow valve were broken in the first dismantling. The
Air hose is fixed anywhere with union nut. This is very well thought of, however, broke the
Plastic thread everywhere when the mother come off except at the pump. Overtighten the hose is not fixed. Here's an error on the part lay ahead or at the plastic variety. At the pump outlet, another plastic is used. Thus everything moves aussser the pump after the first use in the bin.
The pump is buzzing at the beginning very loud. This leaves after about 4 days considerably. After the JBL SilentPro 100 is identical as the Eheim 100 when new. Positioning on a towel etc. is always essential, otherwise the vibrations are transmitted. This loud and it runs away.
Eheim 100:
Very well made and the only variable in performance. However, it brings the minimum performance compared. Can be operated without backing, better and more quietly with. Good diaphragm pump, but also the most expensive. Delivery with great outlets and hose. First choice for use as a bubbler / aerator.
Supplement for a term of 3 months. After running quieter than the Sera Air 110, the power has noticeably diminished but, significantly more compared to Sera Air 110.
Sera air 110 plus:
Cheapest pump and quietest pump! The water outlet of the order-driven sponge filter and the additional AquaClear 20 HangOn filters are clearly louder. Without backing just as quietly as underlaid with towel. Not running away. Processing is simple, clean and functional. Included was a Ruecklaufsicherung or valve.
First choice for use on the filter. With me on the sponge filter Sera L 150th strongest of pump with most water outlet.
