After you've allowed the saltwater mixture for at least 24 hours, it's important to check the salinity/ specific gravity again. This can alert you to potential imbalances that need adjusted. Adjust the specific gravity levels until they reach the optimal level of 1.020 to 1.024. Add more salt if they are too low and more water if they are too high. Just as salinity is important to the wellbeing of your fish, so is the water temperature. Once you've tested and adjusted the specific gravity, check the water temperature. It should be the same temperature as the water in your aquarium. Keep heating it if the temperature is too low. Remove the heater and keep checking the temperature until it reaches the optimal range of 72-75 degrees Fahrenheit for fish only and 75-78 degrees Fahrenheit for reef systems. Be aware that adding salt water at a different temperature than your aquarium will cause a change in temperature for your aquarium. This could harm the health of your fish. When all of the water levels are optimal, you can begin adding the new saltwater to the aquarium. Make sure to add the water slowly so that it doesn't shock any fish or other life in the aquarium. Keep checking the temperature and salinity of the water to ensure the levels remain stable. Add your fish back to the aquarium once it is filled to the appropriate level. You may want to consider double checking the salinity and temperature before adding the fish if you are concerned.

summary: Monitor the specific gravity. Measure your aquarium's temperature. Pour the saltwater mixture into your tank.

Antioxidants are very good for your skin; they preserve collagen and maintain your skin's elasticity. Make sure that the cream you purchase contains both vitamin C and vitamin E, since these antioxidants work best in combination. Follow the directions on the packaging and apply antioxidant anti-aging creams daily for best results. Purchase anti-aging skin creams at any large drugstore or pharmacy. Be aware that, since these products are not technically drugs, they haven't been put through the rigorous testing processes that drugs have and may not fulfill all of the claims on the packaging. If you're less concerned about the elasticity of your skin overall and more concerned with preventing facial wrinkles, a retinal cream is your best bet. Retinol is a vitamin A compound that, when applied to skin on a daily basis, can increase the skin's elasticity. The compound works by breaking down free radicals in your skin and preserving the collagen in skin cells. Apply the cream 12 times a day as directed on the packaging. Keep it up for at least a month, since it'll most likely take that long for you to notice any results. Skincare creams and other products that contain these acids will exfoliate the upper layers of your skin, wearing away and removing dead and wrinkle-producing skin cells. This chemical exfoliation will expose younger and more elastic skin, and should also stimulate this new skin to grow evenly and retain its elasticity. The family of hydroxy acids includes alpha hydroxy, beta hydroxy, and poly hydroxy acids. Beta hydroxy is also known as salicylic acid. Purchase skincare products containing hydroxy acids at any large drugstore or pharmacy. They're also available through major online retailers. If you've used an over-the-counter skincare product (e.g., a retinol cream) for several months with no noticeable effect, ask your general practitioner to refer you to a dermatologist. The dermatologist can write you a prescription for a high-strength cream that will aggressively rejuvenate collagen and increase your skin's elasticity. If your skin has sustained serious sun damage or has lost nearly all of its collagen, the dermatologist may suggest an invasive procedure such as Botox injections or a skin-resurfacing procedure.

summary: Apply anti-aging creams that are high in antioxidants. Look for anti-wrinkle creams that contain retinol. Use hydroxy acids to remove dead skin and encourage elasticity. Visit a dermatologist for a prescription-strength anti-aging cream.

While the elements of the routine stay the same (eat, play, sleep, in that order), the length of the elements and the strategies you might use will vary as your child becomes more aware, interactive, and alert during the day and more conscious of your absence at night. At 6 months old, most babies should not need a nighttime feeding, especially if he/she is eating solid food during the day. When your baby begins to sleep through the night, you can stretch the period of activity to 2 to 2.5 hours of playtime between naps. There will also be times when you may need to be flexible with the schedule, such as vacations or when you need to run errands that take longer than 2 hours. During nap or bedtime, babies of this age often "talk" to themselves or babble, or cry out of tiredness to help themselves fall asleep. It's important that you don't rush to her before she has had a chance to settle in for sleep. Listen to the sound of the cry. The most common signal that she wants to be comforted is your child holding out her hands to you. When you pick her up, hold her in a horizontal position and say soothing words before placing her back in the crib. If she gets more upset, walk away from her crib and avoid eye contact. You may be a distraction. At this age, your baby has become more aware of your absence and may benefit from an item that can help comfort and sooth her to sleep, such as a small, soft blanket or favorite sleep-safe toy. If possible, try to use the same object at every nap and bedtime, and try to keep the toy or blanket in the bed only. This way, the baby will learn to associate the transitional item with sleep and not with playtime, and will be more likely to use it to sooth herself to sleep rather than playing in the bed.
summary: Adjust the routine as your baby grows. Watch for your baby's cues before you pick her up. Introduce a transitional item.
