INPUT ARTICLE: Article: Drain the remaining water out of the tank through a sieve into the sink. This will prevent any gravel from falling down the drain. Remove any decorthat is in the tank as well. You can simply set it on top of the gravel in the sieve. Fold the gravel with your hand and shake it side to side to get the dirt, poo, and left over food out. Use your hands to do it really thoroughly. Use a soft scrubber to scrub the glass. Dry the decor well with a paper towel and put it to the side. Never use soap on anything in a fish tank, including the tank itself. The residue is likely to remain and hurt your betta. Place the gravel and plants back into the tank before you refill it. Then pour new water into the tank and condition it. Follow the directions on the package of conditioner to determine how much conditioner to put in your fish's tank. Use a plastic spoon to stir the water, making sure that the conditioner is mixed into the new water thoroughly. Remember to reserve enough room for the original water that you took out of the tank. Pour the old water you reserved back into the tank once the new water has been conditioned. Stir it all together well. The tank water must be the same temperature as the water was before, and should be between 72 to 80F (22 to 27C). Your fish WILL die from stress if you change the temperature too quickly. Water coming to room temperature could take a while. Check the water after 24 hours using a thermometer to make sure the water temperature matches the ambient temperature in the room. If it is not room temperature, wait a few more hours and then check it again. Slowly put the cup (where you kept your betta) into the tank and tilt the cup a bit. Your betta will slowly come out of the cup by itself. Be gentle while you're doing this, as you might hurt it's fins. Keep an eye on the betta. Once you let it go, it'll soon start exploring the tank. Set your tank back to where it was and enjoy as it swims around observing everything!

SUMMARY: Empty the tank. Run the gravel under warm water. Rinse the tank and decor with warm water. Refill the tank. Wait 24 to 48 hours for the water to settle and come to room temperature. Reintroduce the betta to its tank.

INPUT ARTICLE: Article: This cap will be in the center of the hub and can be removed by simply prying away from the hub. This will expose the retaining nut. There will be a pin in front of the retaining nut that prevents the nut from loosening (referred to as a cotter pin). Remove it by straightening the bent end of the pin and prying it out of its hole with pliers or a screwdriver. Using a wrench or ratchet, turn the nut counter-clockwise (to the left) to loosen it. If the nut is stuck lubricate it with WD-40 or similar lubricant. Some drums have small bolts holding them to the hub. If this is the case you will need to remove those bolts. Pull the drum straight off of the hub. You may have to wiggle a little to get it started. If the drum appears stuck and will not pull off, you should: Check to make sure all bolts holding the drum to the hub are removed. Check to see if the drum is getting caught on the brake shoes. This step is only necessary if your drum is getting caught on the brake shoes. You will need to look on the back side of the backing plate (the steel plate on which the brake components are mounted) for a small rubber plug. Removing this plug will provide access to the brake shoe adjuster. Use a flat head screwdriver or a brake adjuster bar to retract the brake shoes. The adjuster is designed to self-adjust the shoes into a tightened position, so loosening them may be tricky. If the drum gets harder to turn as you adjust, you are going in the wrong direction. Once the drum is removed you can continue.

SUMMARY:
Remove the grease dust cap. Pull out the cotter pin. Remove the retaining nut. Inspect the drum. Attempt remove the drum. Retract the brake shoes.
