To clean a fish aquarium, follow these steps: 1) First scrape off any algal bloom from the inside of the glass. You can either use a long-handled scraper for this, or a magnetic block-scraper which has an abrasive 'inner half' that is moved by hand from the outside. These are less messy and don't make a scraping noise, but are not as manoevurable as a long-handled scraper- the choice is yours which you buy. 2) Do a part water-change using a vacuum syphon. Syphon pumps are available that drain the water out of the tank, and are equipped with a wide nozzle at one end that you can push into the gravel at the bottom of the tank to vacuum out all the collected 'gunk' (i.e. fish faeces, old bits of food, rotted weed etc.) These will also remove old water in the process- remove half to 2/3rds of the old water (NO MORE!) and drain it into a bucket or similar. 3) Replace with cold clean water for goldfish, VERY SLIGHTLY tepid water for tropical Freshwater Fish. Immediately after doing this, add an 'aqua-safe' additive to remove the harmful mineral deposits found in tap water (these are fine for us, but can be harmful to the fish). There are a number of different makes on the market- I am based in England, where brands include Tetra and King British, but there is also a very good US brand called Doc Wellfish that I've used. If you ask at your aquatics supplier for additive to make tap-water safe, they'll know what you need. Make sure that you add the exact amount stated on the bottle. 4) Finally, if you have live weed in the tank, check this for signs of decay- remove any skanky leaves or (if necessary) whole plants, and replace with new. ...and there you are! A clean, healthy tank!! On average, it should be done about once every 6 weeks.

How did my fish tank magically clean itself?

I suggest that you learn more about your fish in your aquarium. One of your fish might be a bottom sucker which means that they eat all of the dirt on the side or bottom of your tank. If one of your fish are bottom suckers, that's probably the reason why your aquarium is clean. If none of your fish are bottom suckers, than somebody must be secretly cleaning your tank for you.
