Garden & Pond Top Tips

Control Weeds This is the one pond problem everyone has to face. There are five kinds of aquatic plants-algae, floating, emergent (foliage above the water), submersed (most of the plant is under water) and floating leaved. Some plants are desirable. Plankton algae is a source of food and oxygen. Filamentous algae is that green slime draped over your hook. (It's not good.) There's a tipping point when weeds begin to take over a pond, says Ian Menzies, business manager for Imas Aquatic & Garden Services. The pond has to be constructed carefully, or in a short time "you get a wetland," notes Menzies. IMAS sells a line of aquatic products to manage nuisance and exotic weeds and algae.

Eight metre high 7 piece fountain configuration

We were called in to establish why an existing fountain display had started to under perform. The fountain had been installed some ten years ago and hadn’t been physically touched in the last five. Ordinarily the fountain would achieve a height of approximately eight metres; it was now producing half of this.

Not being familiar with this installation, we set about understanding the fountains construction. This was impeded somewhat by its position in the middle of an incredibly large pond, which was approximately three feet deep.

The whole configuration weighed in excess of 150kgs and was based around two enormous submersible pumps, six medium shaumsprudler (foaming) jets and one centrally positioned large shaumsprudler (foaming) jet. This was all bolted to a supporting galvanized tubular frame work.

Further to four of us wrestling the beast out of the water, we recognised the frame work was rotten, one pump had expired and the plumbing to three of the fountains heads needed repair.

The whole configurations needed to be fully refurbished, so that’s what we did!
