Re: The warning signs go unheaded
yep some wise words there from Greg.
Tankie I think you are right to be concerned. We are now having an Indian summer which gives high temperatures when all the deciduous plants are rotting back. Those two ingredients spell danger in any enclosed water. The nitrogen cycle just cannot operate properly in those conditions and all the time the water temperature is rising. My advice, for what its worth, get those aerators on during the day but off at night so nature can do her job. The problem with alot of surface aerators is that they simply arent up to the job and dont oxyginate the bottom where all the decaying is taking place. The answer is a sub surface aerator.
Ironfever what you say about the aeraters is a common mistake. this is from one of my IFM hand books The dissolved oxygen problem in ponds can be accentuated by running aerator during the day and turning it of at night. This strips out excess oxygen in the afternoon so that there is less to use up in resperation overnight .It is best to run an aerator [such as a fountain] all the time or just at night. I know it sounds a bit odd but that is the way it works. At church lake they run normaly 7pm to 7am and that did not cope they should have run them 24hours but did not notice till it was to late .I would not like to have been one of the people on that fishery when this happened Iwould not be happy if it was my water and I left staff to look after it for it to go ti*s up.
