  • SUPERIOR PERFORMANCE! Our premium carbon has been super cleaned and is HUNGRY TO RAPIDLY TRAP CONTAMINANTS and TOXINS from your aquarium water. This is great for you because you will have a clearer, odor free aquarium while the exceptional water quality will help your aquatic friends thrive. (This carbon granules are small in size and work best with our FINE MESH FILTER MEDIA BAGS, ASIN: B0737Z7DQY)
  • BREAKTHROUGH! A huge problem with other aquarium activated carbon is that the pores are packed with ash that a simple rinse will not wash away; these pores should be clear and clean. This problem is solved with our carbon! How? After heat activation, our carbon goes through a rigorous cleaning to deep clean the pores. You never have to suffer buying unclean carbon.
  • ELIMINATES ODOR AND DISCOLORATION! Our activated carbon, also known as activated charcoal, removes foul odors from aquarium water LEAVING A CRISP CLEAN SMELL. Our active carbon has large internal surface area which rapidly adsorbs dissolved pollutants from water including yellow-brown tint, toxins, chlorine, most medications, and some heavy metals. Our Premium carbon works best in our FINE MESH FILTER MEDIA BAGS (Sold Separately) or similar bag.
  • CLEANER AND LAST LONGER! When rinsing typical carbon everything can get covered in black dust including your hands and sink. Our premium carbon makes rinsing easy since we clean and wash out a majority of the dust and fines. What makes OUR CARBON LAST LONGER is our exclusive cleaning opens up large surface areas inside each granule allowing it to trap more organic compounds.
  • COMPLIMENTARY MEDIA BAG: package includes free reusable fine mesh media bag to use with our carbon or other filter media. The mesh bag will keep the carbon contained and still allow water to flow through.

How to Turn Fish Water into Plant Food

Read the details on how to use aquarium water to water your plants.

Steps Required

Place a clean bucket on the floor near the tank, large enough to hold the amount of fish water removed or one that can be handled easily, such as a 5-gallon bucket. The bucket size needed will vary depending on the size of your aquarium. Use more than one bucket, if needed. You do not want to spill the water when you are moving it.

Clip the end of the siphon hose to the side of the bucket to ensure the water goes inside it. Use a gravel vacuum to clean the tank as you siphon the fish water out. Move the gravel slightly to get all of the debris from it.

Continue to siphon the fish water from the tank, until you have removed the required amount. Keep an eye on the bucket to ensure you do not allow the water to overflow.

Remove the gravel vacuum from the tank and empty the water from the hose into the bucket. Replace the water in the aquarium, as needed.

Pour the fish water carefully from the bucket into a watering can to make it easier to water plants in containers. Or pour the fish water directly from the bucket over larger planted areas outside.

Save any extra water in a large container to use later. Use the aquarium water on your vegetable garden, bushes, trees or your flowerbed when needed.

Warnings

Do not use buckets that contained hazardous or poisonous materials to drain the fish water in, which could harm your plants.
