Aqua One ProVac Aquarium Gravel Cleaner

Directions:

• Place gravel cleaner 10cm above the level of the gravel and lower the end of the hose into the bucket. 2. Squeeze the the priming bulb a number of times to start the siphon. 3. Once siphon begins, force the mouth of the cleaner into the gravel bed. 4. Move to the next area of gravel and repeat the process untill you have cleaned the entire gravel bed, or until you have removed the desired amount of water. 5. Once you have removed 25-30% of the aquarium water refill your aquarium, be sure to add some Aqua One water conditioner.
• Make sure you have all the necessary cleaning aids before you start the siphon. We recommend a bucket and a towel in case of Spillage, and Aqua One Water Conditioner to add to the tank water you will use to refill the tank.
• Handy tip - this is a good time to use your glass cleaners to scrape any residue off the glass as any additional debris can then be cleaned up with the vacuum process!
• Place your ProVac 10cm above the level of the gravel, and lower the clear tube into the bucket. As you lower the hose into the bucket get ready to start the siphon.
• Squeeze the the priming bulb a number of times to start the siphon.
• Concentrate on small sections of gravel at a time, by pushing the vacuum into the gravel then slowly lifting the vacuum out of the gravel. You will see some gravel travel up the main body o the cleaner. Do not worry, as this gravel will fall back into your aquarium as the debris is separated.
• Once you have completed the water change (approx 25-30% is recommended with regular maintenance routines),  prepare your new aquarium water by adding water conditioner to remove chlorine and heavy metals. 
• If you have sand substrate extra care should be taken when siphoning, and you may need to siphon above the surface of the sand to prevent it from being sucked into the tube.
• Care should be taken with planted aquariums to not disturb the root systems.
