2 Cleaning Your Channel Naturally Establish Ecological Balance with Wildlife Enhancement Adding aeration to lakes, ponds, and channels is the best method to control water quality and algae. It is also important not to overlook aeration in swallow basins and in bodies of water which have a large organic load and that are typically mucky at the bottom. We strongly promote air diffusion at the bottom as the best form of aeration. Fountains and Cascades are aesthetically pleasing and offer some surface aeration but we recommend bottom air diffusion as the most efficient way to improve and maintain good water quality. Aeration is basically the injection of micro-air bubbles into the water to supply oxygen to your lake, pond, channel, canal, lagoon, etc.. The water is turned and circulated from bottom to top by air diffusers that oxygenate the water. Aeration is effective all year round and is a key ingredient in maintaining a healthy aquatic environment. The proper level of oxygen is what drives everything within a body of water. Natural water quality improvement is largely dependent on teams of beneficial microorganisms. One group starts a process, which is continued by others. A pond s condition deteriorates when its bottom environment cannot support aquatic life. Often many natural lakes do not include essential members of these microbial teams and it s water quality slowly degrades. Time, location and the seasons will affect your pond often resulting in bad smells and muck build-up. This is the natural aging process which, if left un-checked will rapidly deteriorate the quality of your pond or lake. In addition to aeration, adding safe and natural bacteria which feeds on organic matter will drastically improve your channel. Diversified Pond Supplies, Wapakoneta, OH

3 Controlling Blue-Green Algae with Aeration * * source: Aquatic Eco-Systems Inc The Problem -- Blue-green algae, also known as cyanobacteria, can form unsightly and unhealthy algal blooms. Certain blue-green algae (Microcystis, Anabaena and/or Aphanizomenon) produce harmful toxins that damage nerves, cause muscle tremors, damage the liver and cause cancer. Recent evidence has shown that the probability that any blue-green algae bloom will be toxic is 45-75%. Since laboratory tests are needed to confirm toxicity, experts recommend that all blue-green algae blooms be treated as if they were toxic to humans and all animals. A Solution -- Artificial mixing of lakes using aeration has been shown to shift the dominant resident planktonic community towards more desirable green algae and diatoms. Aeration and destratification have been shown to dramatically reduce the abundance of Microcystis by circulating the water and reducing the amount of time the blue-green algae spend in water with enough light available for photosynthesis (photic zone). Mixing eliminates another condition for bluegreen algae growth: the stable, warm layer of water that can form at the surface of lakes or ponds during warm months. In addition to removing blue-green algae from the light zone and creating circulation, synergistic airlift destratification systems also dramatically increase lake bottom oxygen concentration, which reduces the level of phosphorus a key nutrient for algal blooms released from lake sediments.

Bubble Tubing Bubble Tubing is a proprietary Canadian-made, lead-free, self-sinking, flexible, fine-bubble diffuser tubing available in 1/2"and 3/4" airline sizes.

5 Bubble Tubing Bubble Tubing is a proprietary Canadian-made, lead-free, self-sinking, flexible, fine-bubble diffuser tubing available in 1/2"and 3/4" airline sizes. Bubble Tubing can be used for commercial applications including wastewater and aquaculture. The unique tubing is also used for aerating ponds, water-gardens, long narrow waterways (channels). The 1/2" Bubble Tubing can be run in continuous lengths of 200 feet and is very easy to install. This self-sinking tubing has two rows of tiny holes 1/2" apart along the entire length of the tubing and when air from the compressor fills the tubing the holes open and release tiny air bubbles into the water. As these bubbles rise together they create a moving water column with a vacuum effect that pulls water from lower depths towards the surface. It contains no lead or dangerous heavy metals.

Why Linear Aeration with Bubble Tubing Works Bubble Tubing set in the bottom of a shallow canal will mix water with more efficiency because the tiny diffuser holes on the tubing, spaced 4 per inch,

6 Why Linear Aeration with Bubble Tubing Works Bubble Tubing set in the bottom of a shallow canal will mix water with more efficiency because the tiny diffuser holes on the tubing, spaced 4 per inch, are spread out over a larger area than when using a single disc or discs. Running a single line or multiple lines of tubing allows for greater dispersion of bubbles throughout the canal and enables a larger area to be treated with beneficial circulation and oxygenation. Using Bubble Tubing is easier than discs or air-stones because it is self sinking and flexible so there are no weights to attach, bases to fill, or plumbing parts to break. Simply uncoil it from the back of your boat without the need for weights or heavy bases full of gravel. Rising bubbles from the Bubble Tubing are gentler than the frothing splash of discs or air-stones and because the Bubble Tubing can run in long lengths it can get quality aeration into vast areas. Homogeneous bubble movement along the Bubble Tubing line(s) ensures an even mixing and gentle circulation action. The canal surface remains calmer and the mixing and circulation is more efficient and extensive. Diversified Pond Supplies, Wapakoneta, OH

7 Why Diffuser Discs & Air-stones Don't Work in Shallow Ponds or Canals Using traditional forms of diffuser discs in shallow canals can be less efficient as the rising bubbles are so closely concentrated that there is little rising lifting action that can occur before they splash at the surface. The aeration is less effective and the surface of the water is in a constant state of aggressive agitation. At greater depths the disc or air-stone type diffuser is highly effective but in shallow waters the resulting circulation is overly concentrated and does not positively impact the entire body of water to the extent of linear aeration using Bubble Tubing, beyond creating waves and frothing water. Plus, many discs are often needed to effectively aerate shallow areas adding to expense and tubing runs. In shallow canals, diffuser discs or multiple disc assemblies create minimal overall circulation because the bubbles are concentrated in a small area. Bubble Tubing changes all that! Concentrated rising bubbles from disc diffusers cause localized frothing over the discs yet leave other areas stagnant, un-aerated and non-mixed. Diversified Pond Supplies, Wapakoneta, OH

Bubble aeration excel where small amounts of aeration, circulation and carbon dioxide degassing are needed in many locations.

9 Small Bubbles Are Better * Bubble type aeration systems are replacing many mechanical aerators because of their low maintenance, reliability, safety, flexibility and overall efficiency. Bubble aeration excel where small amounts of aeration, circulation and carbon dioxide degassing are needed in many locations. Bubble aerators are also better at removing gases, such as ammonia and carbon dioxide. Diffusers are made to deliver either coarse (approximately 6 mm), medium (approximately 3 mm) or fine (approximately 1 mm) air bubbles. * source: Aquatic Eco-Systems Inc

28 Typical Application Scenarios De-icing of Docks & Water Structures For de-icing one or several lengths of Bubble Tubing TM is placed under or around the dock to circulate the deeper warmer water. This circulation provides and open area free of ice which prevents ice expansion damage to docks, boat slips, etc. Open areas in the ice also promotes winter oxygen diffusion and a means for harmful gas to escape. The oxygen depletion and harmful gas is caused by decomposing leaves, dead algae, fish waste, etc.. This combination can become a lethal resulting in winter fish kills. Keeping areas of water open attracts waterfowl and other winter wildlife. Diversified Pond Supplies, Wapakoneta, OH
