If you are following the basic rules for keeping fish which are . :- 1 inch of fish needs a minimum of 1 gallon of water. Every tank needs a permanently running cycled filter. :- Every tank needs at least 50% of its water replaced every week. There should rarely be a need to empty the tank completely. Bettas are bubble nest builders so if there are eggs they will be in a mass of bubbles at the surface of the tank. A male Betta will not tolerate another Betta in its tank with him so if you have two Bettas in a tank they are either too young to fight or they are two females that will not normally fight. To clean the tank you should put the fish into a large container containing water of the same temperature as that of the Bettas tank. You clean the tank properly and set it up (don't forget to add some chlorine remover) and please do not replace or remove all the filter medium. Some of the bacteria are needed to keep the filter working properly. Then equalise the water temperature before returning the fish.

If you intend to keep your vehicle's engine clean, change it every time you change your oil. The filter holds the dirt your engine generates. Hence the dark color of your oil as it ages and is pumped through your engine. Dirt is dirt. Get it out.

this is actually a very simple task. remove the bolts that hold the terminals on. slide them off and clean them with a wire brush. remove the nut that holds the metal bar that holds the battery in place. replace the battery. replace the nut, tighten it. replace the terminals and tighten them.
