Q: Remove debris like leaves and algae from the bottom of the pool once the water is drained. Then place your water hose at the deep-end side of the pool. Position it near the ledge so that the water will run over the tile when you turn it on. Because the acid solution emits noxious fumes and is harmful if it gets onto your skin and body, rubber boots, safety gloves and goggles, and a respirator with an acid approved filter are necessary. For extra precaution, wear a protective suit that is chemical-resistant. You can use a plastic bucket. Make sure to slowly add the acid to the water and not the other way around. Because the acid will fizz and emit fumes when you pour it into the water, make sure you are wearing your respirator, goggles, gloves, and protective clothing. You can purchase muriatic acid and acid-resistant cleaning tools from your local pool maintenance store or online. Starting at the deep end of the pool, work the solution into the grout with the brush. Working on small sections at a time, scrub the tile with an acid-resistant scrub brush. Once the calcium silicate scaling is removed, rinse the tile with water using the hose. Alternatively, fill a watering can with the solution and use the can to pour it onto the tiles. Then use the acid-resistant scrub brush to clean the tile. Repeat this process until all the tiles are cleaned. Add 2 pounds (.9 kilograms) of soda ash for every gallon of acid. Do this once you are done cleaning all of the tiles. The soda ash neutralizes the acid so it can be safely removed from your pool. Do this using a water pump. Once the acid is pumped out, rinse the pool with the hose. Then proceed to pump this water out of the pool as well. When the pool is completely rinsed and cleaned, refill it with water. When rinsing the pool, make sure to rinse your boots, gloves, goggles, and protective clothing with water as well. Rinse until all the acid is completely gone. Discard any unused acid at your local hazardous waste disposal.
A: Drain your pool. Wear protective clothing. Add 1 gallon (3.8 liters) of muriatic acid to 1 gallon of water in a bucket. Apply the solution to the tile with an acid brush. Add soda ash to the acidic solution at the bottom of the pool. Pump the neutralized acid out of the pool.

Q: Find that person you know will be real with you, and ask their opinion. Often when we're in crush-mode we can't get a good perspective on the situation. Your friend may be seeing something you don't, and could save you a lot of heartache, or she could give you the extra push you need to make a move and ask him out. Guys who are already in relationships are sometimes extra attractive to single girls. It may be because one girl has already given him her approval as boyfriend material, so you know he probably has good qualities. You may feel competitive with the other girl, or you may get a temporary self-esteem boost from stealing someone else's guy. Let their relationship run its course and only pursue the guy when he's single. Does he spend all weekend in a dark room playing video games while you prefer to be out hiking and camping in your free time? Do you have similar values? Being different doesn't have to be a deal breaker--you may end up really complimenting each other and learning about things you never knew you liked. Consider if your differences can be worked through. If part of his personality is that he's a huge flirt and that makes you uncomfortable, it might lead to major problems down the road. Ultimately, it's up to you to figure out whether or not you like this guy--you know yourself better than anyone else. Don't make yourself crazy or miserable trying to figure it out. When you feel something as intense as a crush, it can seem like the most important thing in the world. But remember there's more to life than this one guy--don't forget about your friends, your schoolwork, your family, or that there are tons of other guys out there!
A: Ask a trusted friend what they think. Back off if he's already taken. Think about whether or not you are really compatible. Trust your instincts and don't overthink it.

Q: Gardeners should keep in mind that most conifer species, with the exception of yew, cannot survive a severe pruning. Although the green foliage can be trimmed, the brown areas of old growth should be left alone because these places will not regenerate if cut. Some conifers have an area in the center where no foliage grows, but this is normal and not indicative of any problems. In trees where this is the case, gardeners should avoid pruning into this area because doing so will result in a lopsided tree. The plants will not grow back to cover up the hole. Therefore, tree trimmers should check the foliage areas before making decisions about which branches to lop off Although wanting to remove the lower branches of a tree is understandable, gardeners who do so may end up with an unsightly specimen when the tree gets taller. Therefore, tree trimmers should exercise restraint and only remove the bottom branches when it becomes absolutely necessary. Evergreens should not be topped, or cut off at a certain height, because this will produce trees that are anything but attractive. Trees that are topped are also at a greater risk for disease and other ailments. Conifers should not be pruned later in the summer or in the fall. Late season pruning can result in new, lush growth that will not have a chance to mature before the cold, damaging winter weather.
A:
Be aware that most conifer species will not survive a severe pruning. Refrain from pruning into the empty, central area of the tree. Only remove the bottom branches of trees when absolutely necessary. Avoid topping evergreen trees. Do not prune conifer trees too late in the year.
