When soaked, the gypsum wallboard material settles into place inside the pond with little to no movement. Sheetrock is an excellent approach to seal the pond's weak spots. Pure gypsum, on the other hand, is a more effective alternative. Unlike drywall, pure gypsum is free of toxic chemicals and additions to plants and wildlife. It can be applied directly over existing soil or concrete.
The best time to put up sheetrock is when the pond is not in use. If the sheetrock must be removed for maintenance or repairs, wear protective clothing and equipment safety shoes. Use a utility knife to cut out any damaged area before removing the sheetrock.
Pure gypsum has many benefits for your pond. It reduces algae growth because there are no toxic ingredients to harm aquatic organisms. The wall created by this material is also very durable and can help prevent erosion caused by wind or water.
Sheetrock may seem like the easier option but it comes with many risks that can cause serious damage to your pond. If you choose this method make sure you have adequate training for the job. And remember, wear protective clothing and equipment safety shoes when working around liquids and gases!
Gypsum is commonly sprayed at a rate of 1,000–2,000 pounds per acre of surface area. Apply gypsum to the pond water so that it is entirely and immediately mixed in. It should be premixed and pumped or sprayed as a surface slurry, or put into the propeller wash of a high-speed outboard motorboat circling the pond. The gypsum will settle to the bottom where it will remain until it is diluted by rain or melted by heat from the sun or summertime temperatures. Do not add any other materials to promote growth of algae or other organisms in the pond.
Algae blooms are caused by an excess of nutrients in the water. When this occurs, it can cause serious health problems for humans and animals who come in contact with the water. Algae can also be toxic if you eat them. To prevent this, add nitrate or nitrogen compounds to the pond to limit its growth. Some examples are animal manure, fish blood and skin, soybean meal, and tea leaves. Avoid adding raw meat, dairy products, and chemicals that contain sulfur because they will burn and destroy any beneficial bacteria in the pond.
If you want to apply gypsum to your pond as a treatment for algae, follow these instructions: First, stop all input of additional nutrients to prevent further algal growth. This includes removing any fish from the pond and shutting off the tap or hose that supplies water to the pond.
Gypsum acts to clarify water by pulling clay particles together to create clumps, or floccules. As the clay particles cluster together, their weight increases and they finally drop to the bottom of the pond or lake. This process continues until all that's left are the gypsum particles, which are light and float on the surface.
Clay particles can also be added to ponds as a filter feeder for algae and other plants. The particles will eventually fill up with algae and other organisms, which will die and decompose releasing oxygen into the water and taking carbon dioxide out of the water. This is called filtration through sedimentation.
Gypsum can also be used as a pH adjuster in ponds. If the pH of your pond is high (more than 7.8), then it needs acid added to it. If the pH is too low (less than 6.5), then it needs alkalinity added to it. The best way to add acid or alkali to your pond is through the use of limestone or sodium hydroxide (lakeside pool owners should not put salt in their pools) respectively.
Limestone is an excellent source of calcium, which helps prevent algae from growing in the pond. Also, since calcium binds to acid molecules, adding limestone will help reduce the pH level of the water.
Gypsum is generally best farmed and incorporated into clay or heavy soils prior to planting turf or adding turf underlay. If you are unable to aerate the grass beforehand, water the gypsum in well once it has been applied. Never apply gypsum to wet soil as this may cause the powder to expand inside the tank of your tractor or wagon.
The best time to water gypsum is when it begins to dry out. This will allow any residual moisture to evaporate before it has a chance to damage the roots of next year's crop.
Gypsum is safe for animals to eat. However, if an animal does consume some, please consult with your local veterinarian before treating an infection since antibiotics may not agree with them.
This gypsum board's gypsum core is water-resistant. The paper cover is also water resistant. However, if the wood frame is made of pine or other sap-prone material, then the ceiling will need to be treated to make it water-proof.
Gypsum board is used instead of drywall because it's easy to work with, doesn't smell when you install a new heating and cooling system, and can be textured or left flat. The downside is that it's not as durable as other materials; over time, it can become flaky and come off in pieces if it gets wet often enough. Also, since it's made of plaster, bits of glass may remain after it's cut with a saw. Finally, while it's cheap, it isn't exactly malleable, so it can be harder than you think to nail into place some items such as light fixtures.
The good news is that all these problems can be avoided by simply using proper maintenance practices. If you clean your ceiling regularly, use non-toxic paint or adhesive, don't soak the board in water, and don't expose it to direct sunlight, then your gypsum board ceiling should last for many years.
A half spoonful of gypsum added to a gallon bottle of water sample works beautifully. Within a couple of hours, there was a noticeable improvement, and the water was clean within 12 hours. The pond is roughly 12 acres in size and has a maximum depth of around 15 feet. The amount of time it takes for the gypsum to work its way through the pond depends on the concentration used but should be enough time for every piece of debris that floats to the top after adding the powder to reach shore.
Gypsum is used as a water treatment additive because it increases the density of fresh water. When floating debris such as wood or plastic reaches the surface, it creates a barrier against other particles from entering the lake or stream. The rising debris also brings up any particles trapped in the surface film of the water. The gypsum acts as a weighting agent so any material caught in the surface film will sink down toward the bottom of the pond or lake where it can be removed.
If you add too much gypsum, it can cause some fish to move away from the area where it's being dumped into the water.
