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.

Re-commissioning the full pumping system of the pond configuration at Caldecotte Lake Business Park, Milton Keynes

This whole pond configuration (highlighted above) covered an enormous quarter of a mile. The pumping system hadn’t worked for some months and nobody on site had any real idea about how the system had previously operated.

So we carried out a full investigation, provided a detailed report and then set about the task of getting the system operating once again, which I can report we successfully did. To give you an idea of scale to re-prime the system it took three days of continued pumping from the adjacent lake. That’s not to fill it, just to get it working.

The main submersible pump we installed operated a maximum flow rate of 600 litres per minute and was capable of pushing water to a head of sixteen metres!
