In this article, I discuss 7 of the most effective methods to reduce ammonia, which are: Add beneficial bacteria. Perform a 50%-80% water change. Use a detoxifying water conditioner or ammonia remover. Use it at your own risk! Sometimes aquarists use Hydrogen peroxide (3%) in spray bottles to eliminate biofilm. For the record, Hydrogen peroxide is commonly used as an oxidizer, bleaching agent and antiseptic. Hydrogen peroxide will simply erase it from the surface. Pothos plants are fast-growing houseplants. Therefore, they require nutrients faster. Pothos will absorb the nitrate from your aquarium rapidly, more precisely, in 4 to 5 days. Pothos surely is a good choice to lower nitrate levels fast and cheaply. A 20-40 ppm reduction in nitrate levels in the aquarium is feasible. Chemical filtration is a process by which chemical additives remove dissolved wastes from the water. The most common method for chemical filtration uses activated carbon. Other chemical media added to the filter can remove chorine, ammonia or phosphate from the water. The chemical media needs to periodically be replaced. 3. Keep Live Aquarium Plants. If you don’t have any live aquarium plants or if you have very few live aquarium plants in your tank then adding some live aquarium plants can help to lower the ammonia in your fish tank. The live plants will absorb ammonia from the aquarium water and use it as food to grow. 4. Reducing Ammonia Levels In a newly setup aquarium or pond, ammonia and nitrite levels will rise and then fall in the first few weeks, indicating the formation of the biological filter. However, to reduce ammonia levels within the first few weeks use API AMMO LOCK® or PondCare® AMMO LOCK as directed. After AMMO LOCK is added Step#1: Add Ammonia To The Tank. The simplest way to do this is to add fish food to the aquarium. Add in the amount you would if you were feeding the fish and top it up every 12 hours to speed up the process. Once the flakes start to decay, they will release the gas, which starts the nitrification process. Waterlog your driftwood: If you have dried and floating driftwood, pre-soak it for a few days so that it absorbs water, becomes less buoyant and it’ll stop floating. Glue it down: you can also use aquarium sealant to glue the floating driftwood to its position in the tank. 4. Aquarium driftwood breaking down. Zeolite is an efficient substance that rapidly removes ammonia. It can eliminate 90-95% of the ammonia within the first hour of application. If you are looking for an effective way to get rid of ammonia in your aquarium or wastewater, zeolite is a powerful solution. 2. Test the aquarium water for raised Ammonia levels. The size of your fish tank determines how fast its water will get polluted if a dead fish is left in there to rot. A small fish decomposing in a 30-gallon aquarium will likely take a whole day before the water becomes foul. Rf9K.
