Three General Methods For Controlling Aquatic Weeds
Water weeds are often very problematic in most cases if you will leave them untended. Leaving these uncontrolled will allow them time to take hold of your fish pond and grow to such extents as to get them increasingly out of your controls as such literally conquering the pond and aquatic life. Amongst the initiatives often taken to take away the problem of these pond weeds and such like life, we often have the pond maintenance and filtration initiatives which are nonetheless not entirely conclusive in addressing these aquatic weeds as by and by, the weeds will get returning to the pond in thriving life. The three basic means of aquatic weed control are generally the chemical, mechanical and the biological, all of which have their advantages and disadvantages and when well employed will be the solution to your weed invasion in your pond.
Though time consuming, the mechanical method will be the most cost beneficial in the three methods of aquatic weeds removal. An excess of nutrients in the water are often the major cause of water weeds and algae life in your pond. The exchange of the water in the pond in its entirety will be a good way of dealing with this nuisance and would probably be better qualified by some manual labor. You can also use the mechanical filter to remove the algae and weeds which are scrubbed from the substrate. Replacement and cleaning of the filter mats is another step which one should consider to have done after they have the cleaning completed as a step to keep them from returning.
The chemical removal as a method is the other option you can have and this will involve the addition of chemicals like algaecides and herbicides. This method of weed and algae removal is deemed as the being quick and effective style of dealing with algae and weeds and only comes with the negative side of causing complications to the aquatic life you host. The algaecides and herbicides at times contain harsh chemicals which may have a serious effects on the other useful elements of the aquatic life like the plants, other invertebrates making the eco-system habitable and even the fish life in the fish tank.
There are other effects the chemicals for weed removal will have on your fish tank added to the general effects they will have on it-and this is the effects it will have on the biological filters. The reverse effects will be felt when the chemicals have their toll on the biological filters since the good bacteria in these filters are always quite sensitive to these chemicals and as such they will die whenever they are exposed to these and the net result will be the creation of the once more environment of excess nutrients enhancing the growth and life of the algae and weeds.
