A fresh water fish tank requires about 30 minutes to an hour of work a week depending on the size of the tank.
Waht you will need:
1) You will need a clean 5 gallon bucket that has never had chemicals or soap inside of it.
2) A hose or gravel cleaner
3) A bag of natural or synthetic sea salt
I have split the work into two parts the tank which needs to be cleaned ever week on the same day and the filters which can be cleaned every 2 or 3 weeks.
The very first thing you have to do before you start cleaning your fish tank is to unplug your tanks heater if you have one. The heater can not be allowed to be removed from the water while it is hot so make sure to leave it unplugged at least 20 minutes before attempting to remove it. The water help cool the glass on the heater if removed it could crack, or the glass could totally shatter. You should also remember to never stick your hand inside of any fish tank before making sure the heater is not only off but unplugged from the wall. A small crack in the heater could be more then enough to cause a shock to you that can be fatal.
After the heater has ha time to cool you can safely remove...
