Simple steps to changing water.

1. Unplug everything - heater, filter, lights and any other electrical components you have added to your aquarium.
2. Wipe off the sides of your aquarium with an algae pad to remove any algae that may be growing there. Even if you can't see any algae it is there.
3. Use a siphon and a bucket to remove water from the aquarium. Place the large end of the siphon into the aquarium, suck on the hose for a second to get the water flowing through the hose, and put the other end of the siphon into a bucket that is on the floor. Better yet use the Marina Aqua Vac which fastens on to your kitchen sink. The job of doing water changes has just got easier with Marina's new Aqua Vac. Available in either a 25' or 50' length. No more straining your back with heavy buckets. Simply drain and fill. Aquariums West gives this a "Must Have" rating for anyone with an aquarium.
4. Place the large end of the siphon into the gravel about 1" deep. The gravel will spin around and any food or waste will be siphoned out and the gravel will drop back down. Continue to do this over the bottom of the aquarium targeting any special areas that you see decomposing food.
5. Once you have removed 1/3 of the water (you can take out more if it is really bad, up to 75% without damaging your fish. This is only recommended if the tank is really filthy.) and then replace with water that is slightly warmer then the water in the aquarium. Use the appropriate amount of water conditioner, mix it in the bucket and then pour it back in.
6. Check your pH level and tweak if necessary.
