If your pond is rectangular or square the easiest way is to use our pond volume calculator ( on the left). Simply enter the length and width of your pond as well as the average depth. Enter your dimensions in either feet or metres, the answer will be displayed in both litres and gallons. For circular ponds multiply the radius in metres by the radius in metres and then multipy by 3.14 this gives the surface area. Multiply this figure by the average depth this gives the volume in cubic metres.

The green color you are seeing is associated with algae growth suspended in the water. Excessive algae growth is caused by excess nutrients, such as phosphorous. Phosphorous is found in our leaves, grass clippings, and lawn fertilizer. In order to promote healthy water quality, it is important that we keep these items out of the street. Remember, the catch basins are a directly empty into our lakes, ponds, and wetlands. More information >>>

The evaporation rate/quantity depends upon weather conditions such as heat, humidity (or lack of), and wind; also, whether there is a fountain, sprayer, or waterfall installed. You can always check with a local swimming pool maintenance company to see what they have found to be normal for your area.

Testing is necessary for two reasons. First, it is important to know initial conditions to ensure the pH is in range to sustain bacteria growth. Second, this allows the ability to track changes in water conditions over time.

You should test your pond water approximately every week. For small ponds it may be more often and for large ponds, it may be less frequent. For new ponds, test it every few days for the first few weeks in order to get a good basis of where you're pond is at, chemically. After that, you may be able to check it weekly providing you don't add a big change to your pond such as a bunch of fish, eliminating a pump or filter, etc.

Volume weight is determined by using the following calculations for those shipments with dimensions in centimeters: (Length x Width x Height) divided by 6000 = volume in kilograms.

First measure the length, width and depth of the pond. This is good for square or rectangular size ponds. Plug the numbers into the following formula: Average length x average width ? 43,560 = # of acres. For example, say your pond measures 350 feet long and 200 feet wide. To calculate the acreage you put the above numbers in the formula like this: Diameter x diameter ? 43,560 x 0.8 = acres. For this example, say your pond is 235 feet across (diameter) and it is a circular pond.

Measure the length, height and width of the water in the tank - don't forget to allow for the air at the top or any particularly large items in the tank. Then you can either use this online calculator to get volume in UK and US gallons, or you can work it out yourself. Using measurement in inches, multiply length x width x height. This gives cubic inches. To get litres, multiply by 0.01639. Then for UK gallons, multiply litres by 0.2200 or for US gallons, multiply litres by 0.2642.

Check your main shutoff valve and inspect your filter after closing both upstream and downstream valves. Clean if needed. If all valves are on and filter is clean check the irrigation delivery status link on the homepage, or call the irrigation line at 387-5261 for updates, as there may be a break in a line or maintenance may be in progress.

Depends on the size of your pond. For instance, under a normal circumstance, the water level of a 6'x8'x3' pond may drop 1/4" to 1/2" inch every week because of evaporation. When there is a high wind situation, the speed of evaporation may be faster than you expect. Sometimes water can drop a couple of inches overnight. If this happens, do not panic. Just simply add more water to the ponds proper water level.

First of all, you want to be sure your pond kit is accurate and not expired when testing. Be sure to test the same time of the day for accurate results. Next, you want to figure out what is causing the pH to go up. pH can go up by a few conditions such as poor surface water agitation, an increase of nutrients in the water and what composes those nutrients, and what chemicals have been added to the water and from what source.

First of all, you need to determine if your pond water is actually brown or if there is a lot of brown "things" floating in it such as silt, that is making the overall color look brown. So, what you need to do is get a clear jar (like a Miracle Whip jar) and fill it with the pond water. Let it sit over night or longer (24-48 hours).

In general, 1mm diameter bead represents 1ul of alginate volume. Cell concentration in bead should be same as concentration in starting polymer/cell mixture.

Yes - the windmill can be ordered with an optional pumping system that allows you to aerate your water and/or pump water from a well or water supply. The lift is at least 30-40 ft. and can pump approximately 4 gallons of water per/minute.

To determine the square foot surface area of your rectangular or square pond simply multiply average length x average width = square feet of surface. To determine square footage of surface area on your circular pond multiply (half the diameter) x (half the diameter) x 3.14 = square feet of surface.

Unfortunately, no. There is not a single test that can tell you everything that might be in your water. CLS will assist you in determining what analyses will provide you the most useful information within your needs and budget.

Place your pond in a place that will maximize your enjoyment. Consider putting it in a place where you can easily view it from rooms where you spend a lot of your time, such as kitchen or family room. Ponds and waterfalls make wonderful additions to the outdoor areas where you relax and entertain such as decks and patios. Some sunlight is good - too much can cause problems. About 1/2 day of sun is usually sufficient to ensure healthy plant growth.

Often it's not easy. First, carefully check the bottle label and even the cap -- if it says "from a municipal source" or "from a community water system" this means it's derived from tap water. Again, you can call the bottler, or the bottled water program in your state or the state where it was packaged.
