The plus stands for additional power and performance (up to 5000 l/h). And it stands for use in and out of water. These plus points mean that the pump is suitable for a variety of applications – for larger or smaller aquariums. The output can be adjusted as required. A replaceable coarse filter traps dirt particles. And also the quiet running, the low energy consumption as well as its suitability for fresh and salt water are important plus points.
There are 3 models with adjustable pump output up to 2000, 3000 and 5000 l/h.
