Q: Plant your lotuses in mid-spring once the average daytime high is over 70F (21C) and the pond maintains a warm water temperature. To help warm the water faster, you could also use a submersible pond or aquarium heater. Lotus plants will begin to grow only once the water and daytime air temperatures reach 70F (21C). If you don't contain them, lotuses will take over the entire pond. To maintain the water quality and keep fish and other plants healthy, plant individual lotus plants in separate 2ft (0.61m) wide containers. Containers specifically designed for lotuses are wide and shallow; you can find them online or at a garden center. Choose a round container, as square corners would choke the plant. Steer clear of standard aquatic plant basket meshes, which won't control lotuses' growth and could injure the roots. To ensure the lotuses' rhizomes are contained, go for containers without drainage holes. Black containers absorb heat well and can help keep your lotus plants at a comfortable temperature between 75 and 85F (24 and 29C). Black is also inconspicuous. Depending on your taste, you could choose other materials, such as terracotta. If you're using a container, cover the bottom with 4in (10cm) of sand, clay, and aquatic plant fertilizer. Whether you're using a container or planting directly into the pond, dig a shallow hole in the soil mixture for the lotus tuber. Dig the hole in the center of a container to give the tuber room to grow. If you're planting directly into the pond, placing the tubers along the edges in 2 to 3ft (0.61 to 0.91m) intervals will encourage them to spread. If you're planting directly into the pond, take care not to disturb the soil and muddy the water when you dig holes. While it might be a bit inconvenient, you can't plant the tubers directly into the pond before filling it with water. The water needs to time to dechlorinate and heat up to the right temperature. Lay the tuber in the shallow hole with the growing tips facing up. Position the tuber horizontally at a slight angle so the growing tips won't be covered by soil. Then gently cover the tuber with a 112in (3.8cm) layer of the soil mixture, and carefully weigh it down with heavy sand or gravel so it doesn't float. The growing tips are pointed and look like buds. The other end of the tuber is round. After planting a lotus tuber in a container, set the pot into the pond so the top of the soil is about 2 to 4in (5.1 to 10.2cm) below the surface of the water. If the pond is deep, elevate the container on top of bricks. Lotuses can grow in water up to 18in (46cm) deep, but they'll bloom a lot faster if the soil is covered by only 2 to 4in (5.1 to 10.2cm) of water. If you're stocking the pond with koi, plant several lotuses in individual containers. Koi will munch on plants; the more lotuses and other plants you grow, the less damage individual plants will incur.
A: Plant your lotuses once the water temperature has reached 70F (21C). Use 2 to 3ft (0.61 to 0.91m) containers to control your plants' growth. Dig a 112in (3.8cm) hole in the soil. Place the tuber horizontally in the hole. Submerge the container if you used one.

Q: It's the app that has an image of a red, yellow, green, and blue triangle. It's at the top of the page. It's the app with a light-blue circle on a white background. It's the green under the app's title at the top. This will begin downloading the app and install it on your phone. This option will appear where the "Install" button was once the app is finished installing. This will launch the Slydial app. You will need to type your phone number in the first line, and then confirm it in the second line. This indicates that you agree to the Slydial terms and conditions. It's the blue button above the checkbox. Fill out the required personal information to sign up for a free Slydial account. It's the blue button below the three bars. The first time you use the app, you will be asked if you want to allow Slydial to access your contacts or your phone. Tap "Allow". When you use Slydial, you'll hear an advertisement before you are connected to the voicemail of the number or contact you're calling. Select one of the following: Tap Slydial a contact to chose someone from your list of contacts. Tap the contacts name and then tap the mobile number you want to call. Tap Slydial a number to dial a phone number. Then tap Dial. It's the blue button at the bottom. Press the button that has an image of a red phone to hang up and end the call. The contact will receive your voicemail, but won't hear their phone ring.
A: Open the Google Play Store . Tap the search bar and type Slydial into search. Tap the Slydial app in the search results. Tap Install. Tap Open. Type your mobile number in both lines. Tap the checkbox at the bottom. Tap Continue. Type your first and last name, email address, and password. Tap Sign Up. Tap Slydial a contact, or Slydial a number. Once you've left your message, disconnect the call.

Q: The pH is a measure of the concentration of hydrogen ions in a solution. A solution with a high concentration of hydrogen ions is acidic. A solution with a low amount of hydrogen ions is basic, or also known as alkaline. Hydrogen ions, also known as hydronium, are written shorthand as H+ or H3O+. Know the pH scale. The pH scale is usually presented from 0 to 14. The lower the number, the more acidic the solution. The higher the number, the more basic the solution. For example, orange juice would have a pH of 2 because it is quite acidic. In contrast, bleach has a pH of 12 as it is quite basic. Numbers in the middle of the scale are neutral, such as water, with a pH of 7. One level of pH is a 10x difference. For example, when comparing pH 7 to pH 6, pH 6 is ten times more acidic than pH 7. Furthermore, pH 6 would be 100 times more acidic than pH 8. The pH scale is calculated by a negative logarithm. A negative logarithm of base b is simply how many times a number must be divided by b to reach 1. The pH equation can be seen as follows: pH = -log10[H3O+]. The equation can sometimes be seen as pH = -log10[H+]. Know that whether the equation has H3O+ or H+, they are the same. It is not vital to have a firm understanding of what a negative log is to calculate pH. Most calculators used at high school and post secondary level will have a log button. Concentration is the number of particles of a compound in a solution relative to the volume of the same solution. For pH, you have to use molar concentration for the formula to work out. Molar concentration, which is also called molarity, denotes the number of moles of dissolved compound per liter of solution. Its units are moles per liter (mol/L), also called molar (M). If you're using a solution in a lab, the concentration will be written on the bottle. When working on your chemistry homework, the concentration will usually be given to you.
