Q: Before moving your goldfish into its tank, let the water sit for at least a few weeks. This time is necessary for the tank to provide a healthy biological environment for your goldfish, so be patient! More specifically, allow the tank to build colonies of bacteria, which will develop on the filter and in the gravel. You'll maintain this biological environment via a process called cycling. Once your tank is setup and the filter is installed and turned on, add ammonia. Continue adding ammonia while trying to keep it's amount at 0.06ppm until enough bacteria have developed to eat both the ammonia and nitrites in your tank. Determine your levels of ammonia, nitrites, and nitrates by using test kits designed for this purpose. Continue the process until you get readings that indicate zero ammonia and zero nitrite. Regularly cycle the fish tank by changing 100% of the tank's water while taking care to keep the bacteria that are present in the tank alive. This will help your water "cycle" nitrogen, which is necessary to keep your fish alive. After the emptying the tank of water, add fresh, conditioned water. Repeat the process of adding ammonia and testing for ammonia, nitrites, and nitrates. Once you have reading of zero ammonia and zero nitrite, as well as a bit of nitrate in the water - which is produced by the bacteria - your tank has been successfully cycled. Keep the water slightly warmer during cycling to increase the speed of bacteria growth. You can even borrow bacteria from a friend who already has a well-established, recently cycled fish tank. Seed your own tank by taking some of their gravel or cutting off a piece of their filter's sponge and adding it to your tank. Alternatively, add a bottle of ready-to-go bacteria from the fish store. If you go this route, still expect to add some ammonia and test until the tank is balanced. You need to change the water even more often than you cycle it. To curb the buildup of waste, change 25-50% of the tank's water once a week. Leave some of the water in the tank, however, to maintain a healthy amount of bacteria developed by less frequent cycling. When changing some of the tank's water, rinse the filter and any tank decor with water your remove from the tank. Never use tap water to rinse anything that goes in your tank. Only add clean water that you've treated with conditioner.
A: Grow healthy bacteria in your tank by adding ammonia. Cycle the fish tank's water once a month. Speed up the cycling process with a few tricks. Change some of the tank's water once a week.

Q: Now that you have your sketch you need to outline it to make it neater. Create a new layer. Click the pen tool, and click "freeform pen tool" Since the pen tool smooths your line, you may need to erase and redraw it. (not the whole thing only the line, don't worry) Now you need to stroke it. Right click and click "Stroke Path" and then Delete the old line by doing this. Right click and select delete path. Here we see this: You don't want the yucky blue lines right? You do this: Some are thick and misshapen what we need to do is taper. Now it is time to add color.
A: Outline it. Outline one of your lines. You have a line. Set to paintbrush or pencil You should have this now. Delete the rough sketch. Repeat for all the rest of the drawing. Clean up. You have this. Look at the lines. Grab the eraser and taper the lines by erasing the edges of the line. Do it to the rest of the lines. Add color.

Q: Apply a deck cleaner, degreaser, or stain remover to the stain. Rub the stain with a soft nylon brush. Add more pressure if the stain isn't being removed. Rinse the cleaner with water. Oxygenated bleach contains sodium carbonate and mixes with water to create oxygen. Mix the four scoops of oxygenated bleach with warm or hot water until it is fully dissolved in a five gallon bucket. Pour the solvent over dry stone in sections. Let the solution sit for 10 to 12 minutes. Scrub the first section with a brush while letting the second section sit on the stone. Rinse the first section before scrubbing the second section. Bleach can be used to clean dirt, stains, and algae from your stone patio. Mix equal parts bleach with water in a bucket or watering can. Cover the stone with it. Let it sit for around 10 minutes, then brush the stains with a broom. Rinse it well with clean water. You should probably rinse multiple times. Use thin, plain bleach for this. Don't use bleach that has added detergents and other chemicals. These thicker formulas with added ingredients don't clean as well and may clump on the stone. Just buy basic bleach. Bleach can kill plants if the solution touches it. Baking soda has an abrasive structure that can help remove stains. You can mix baking soda with vinegar, or two parts bleach with three parts baking soda to make a stain-removing paste. Cover the stain with the paste and then use the brush to scrub the stain. Rinse the paste with clean water.
A:
Use a soft nylon brush and cleaner to remove stains. Use oxygenated bleach to clean the stones. Remove dirt and algae with bleach. Try baking soda to remove stains.
