EHEIM accessory kit for VAC40 pond vacuum

Each piece takes the place of the universal nozzle at the end of the suction tube, so you change tools as you go depending on the surface to be tackled. The crevice tool and the round brush work on small surfaces, while the floor nozzle, fitted with its brush insert, covers a wide strip. The pleated filter, on the other hand, is not used for the bottom of the pond: it is fitted to the unit when you use it dry, in a garage or workshop.

It is among the stones that the kit earns its place in a pond. A pond floor is never flat: there is the step of the planting shelf, the angle between the wall and the floor, the gaps between submerged coping stones. Mud builds up there faster than elsewhere, because nothing disturbs it, and a wide nozzle glides over it without picking it up. You therefore find it untouched at every clean, in the same spot. The crevice nozzle gets down into it and the round brush loosens whatever clings. The technique remains that of the VAC40 pond vacuum used on its own: you move forward slowly, in strips, keeping an eye on the water level.

On flat areas, the floor nozzle takes over: paving slabs on a submerged shelf, the step of the planting zone, the floor of a preformed pond. Its width covers a whole strip on each pass, and its brush insert loosens the fine deposit that clings to smooth surfaces. So start with the corners and gaps using the crevice nozzle, then finish with these large surfaces, so that you pick up last whatever the first passes have stirred back into your water.
