Abstract: The invention is a water submersible device that dislodges filament algae or detritus from infected objects such as rocks and disposes the matters into a removable compartment for removal from the aquarium or pond. It has a water pump (1) that not only sucks in water from its water inlet (2) opening but also has a drill bit (3) extending out from the center of the same inlet opening. When it makes contact with the filament algae or detritus on objects, it breaks and swirls them up quickly and disposes them to the water outlet side of the pump. There, contains a collection cup (5) with filter materials (4) for easy matters disposal. The pump is secured onto a rod (7) by a hinge joint (6) for easy angle adjustment by the user holding the handle (8) above water. It is powered by a battery (9) inside the handle.

Abstract: The main invention for this application is the submersed algae killer for fish and corals keeping aquariums. The traditional method of removing hard algae such as coralline alga is just to scrape them off from the glass surface. Not only is scraping hard to perform with existing scrapers on the market, it can also likely to scratch the tank and spread the algae to other parts of the tank. My invention uses two steps to perform the task without getting the hobbyist's hands and arms wet. The algae are being killed first by heating them with boiling water right at the vicinity of the infection. Once the algae are killed, they are not stuck onto the surface as tight as when they are alive. By using the submersed scraper, the second component of the invention, dead algae on the inner surface of the tank can be easily dislodged. Since the algae are dead, the hobbyist does not have to worry about spreading the algae to other parts of the tank.
