The Challenge: Due to poor water quality, the population of midge flies had become a big problem for residents in the Rio Pinar Home Owners Association in Orlando, FL. At 4,376 larvae/m2, a private consulting firm has measured the midge fly population at over 4 times the state nuisance level of 1,000 larvae/m2. Dense midge fly swarms were not only visually unappealing, their excessive numbers were hindering outdoor activities, damaging vehicles and painted surfaces.
The Prescription: To improve water quality and create an environment less conducive to midge fly reproduction, the Airmax® team implemented a proactive pond care system consisting of bottom diffused aeration and beneficial aerobic bacteria. An LS30 Airmax® Aeration System would be installed with all three plates distributed among the deepest areas of the lake, circulating the entire water column 1.3 times per day. PondClear™ and MuckAway™ beneficial aerobic bacteria would then be added to aid in the digestion of organic debris and much to reduce the living space of the midge fly larvae.
The Results: Residents immediately saw improvements in water clarity and pond odors. With oxygen and organic-eating beneficial aerobic bacteria being circulated throughout the entire pond, muck deposits were rapidly reduced leaving midge fly larvae nowhere to hide. Natural predators to midge flies, like bluegill, breem and aquatic beetles, were able to travel to lower depths and consume these larvae thereby lowering the population.
In only 10 months, the midge fly population was reduced by 84% to 723 larvae/m2; well below the set nuisance level.
