article: Spray water on the moss, peat, or other material you've placed at the base of your tank whenever it starts to dry out. Keep this material moist at all times. If you can't spray every other day at least, you could leave an ice cube in the tank, or a rag or sponge soaked with water. The snails may stay healthier if you spray them with water every day or two, but pay attention to water temperature. Spray with warm water in cold weather, and use room temperature water during hot weather or if you have central heating. Most snails are not picky eaters, and will enjoy most types of fresh fruit and vegetable. Wash all food thoroughly in clean water before you give it to them, and cut large vegetables into chunks or slices. Some foods, such as carrots and potatoes, may need to be boiled for a few minutes to soften them slightly. Always let cooked food cool completely before giving it to your snails. Some snails may eat raw meat, raw eggs, brown bread, or (soaked, but uncooked) oatmeal. Experiment to give your snails a varied diet to increase the chance that they are receiving all the nutrition they need. Not much research has been done on the best nutritious diet for snails, and there is disagreement among snail owners about which foods may or may not harm the snails. Here are a list of food ranging from the most to least dangerous:  Salty foods could kill your snails. Avoid anything with salt crystals on it entirely. Avoid pasta, rice, and millet. These starchy foods can potentially cause blockage in the snail's digestive system. Do not feed them to your snails. Homegrown plants may be exposed to car exhaust while growing, which could cause harm. Acidic foods such as citrus fruit, tomatoes, and kiwi fruit may or may not harm snails. Use them in small quantities along with other foods. You can use any source of calcium as long as it is clean and washed. Egg shells or discarded snail shells in your garden will work for the average pet owner. If you are trying to breed snails you may wish to buy more concentrated calcium sources from a pet store, such as cuttlefish bones or pure calcium supplements. Have a source of calcium available in the tank at all times. Replace it whenever it runs out, but use calcium supplements with greater than 20% calcium sparingly. Clean a snail with a toothbrush whenever their shells get dirty. Do not use soap and brush gently to avoid damaging the shell. Pour a few drops of water onto the shell to help remove stuck-on soil. Pick up the snails gently by coaxing your finger underneath their head, then place them on a towel in a temporary container. Remove the old soil to discard in the garden. Use a wet, slightly soapy sponge to scrub the walls and base of the tank to get rid of snail slime marks and scum. Rinse the tank carefully to make sure every trace of soap is gone, as it could harm the snails.  Don't leave the snails untended if the container is small. Do not shut the snails in a container without air. When replacing the soil and other materials in the clean tank, follow all of the steps described under Making a Snail Home

Confirm that the float switch to the pump is connected. Connect a float switch yourself if your pump doesn’t come with 1. Plug the pump into a power source nearby. Prime the pump by pouring a cup of water through it."
article: To keep the pump and systems from running dry, make sure to shut off any electricity in the area you’re draining. This includes any pumps, filtration systems, lights, or electricity sources for a pool, hot tub, well, or flooded basement. Attach a garden hose or a sump hose to the hose fitting on top of the pump. Make sure the connection is tight and secure before using the pump. When draining clean water, you can use a standard garden hose. However, you may want to use a separate hose for dirty or chemically treated water. Designs can vary between manufacturers—some float switches look like 2 small black cylinders, while others come in bright colors and small, flat, rounded shapes. Look for a small device attached to the pump with a black wire and a watertight connection. If your float switch is already connected to your pump, then you’re all set to start pumping! If your pump doesn’t have the float switch already installed, use a hose clamp and a screwdriver to attach the switch.To attach the switch, hook the clamp through the bracket on the back of the switch, then screw it around the upper part of the pump to keep the switch submerged. Tighten the clamp until it holds securely. You can purchase a float switch online or in a home improvement store. The submersible pump will have a power cord connected with a watertight seal, so all you need to do is plug it in! Find a power source nearby, such as an outdoor outlet, or use a heavy-duty extension cord if you need the extra length. This will make the start-up easier on the pump’s internal system. This initial priming can also cut down on the time that the pump needs to prime when you drop it into the water, which usually takes a few minutes. Once the cup of water runs through, make sure to turn the pump off to avoid running it dry and losing its prime.

A multimeter is a handy way to measure the different forces that make up an electrical charge. It’s helpful to have one on hand to test the current in any electrical circuit. Get one that measures the current, voltage, and resistance.  The current is the flow of electricity in a circuit. It is measured in amperes. A current’s voltage, measured in volts, is the pressure pushing the current along the circuit. Resistance indicates how much the circuit resists the flow of electricity. It is measured in ohms. Resistors are small tubes on wires. They don’t actively do anything, but they are important in limiting the electrical current. Without a resistor, the electrical current can become too strong and ruin other components. For example, if you attach an LED light to a circuit without a resistor, the light can burn out. Capacitors are the opposite of resistors. Instead of limiting the flow, they encourage it by storing a little bit of electricity. This way, if the power is disrupted, the circuit continues to work. For example, if you unplug your computer, the capacitors will ensure the electrical current runs smoothly from the battery. These components have + and - terminals that help conduct electricity. When activated, electricity flows through one end and out the other. Diodes have 2 ends while transistors have 3.  Diodes are used to make an electrical current flow in 1 direction only. Transistors are like switches that change the direction of a current. For basic electrical work, you will need a wire cutter and a wire stripper from a hardware store. To do this, cut the wires to the length first. Then, strip about 1⁄4 in (0.64 cm) of insulation off the ends before connecting them to components.  To work with the wire, hold the exposed ends against the components or tape them in place. If you use a breadboard, simply push the exposed end into the hole. When you first begin, you do not need to learn how to solder. Electrical wires are generally all copper. However, they are cased in different colors of plastic to distinguish their uses. Always connect like wires together. Use black and red wires to power your circuits.  Black wires are the main current conductors in a circuit. Red wires are secondary carriers. Blue and yellow wires are uncommon, but are used to carry electricity in complex circuits. White and gray wires are considered neutral because they conduct unused electricity. Green wires are grounding wires which bring the current to the ground for safety.
