How to Bring Down the Nitrite Level in a Salt Water Tank

When it comes to saltwater aquariums, one of the biggest problems you will likely have is keeping the nitrate levels low and steady. You may have resigned yourself to constant water changes and adjustments, but in reality the solution is much simpler. All you need are to get a few new inhabitants and to alter a few bad habits, and your nitrate problem could be solved for good.

Instructions

      Change out about 25 percent of the water every other week. This is more often than you would normally change the water, and you should only do this until you get your nitrate problem solved. Replacing the dirty, high-nitrate water will go a long way toward lowering your nitrates fast.

      Feed your fish in moderation. High levels of nitrates are usually due at least in part to excessive fish waste and rotting food. Be careful to only feed your fish as much as your veterinarian or the manufacturer recommends. Do not just tip the food box upside down over the tank and pour.

      Install a nitrate filter. These filters are usually made of zeolite, and they will effect a change fast. However, they are not a permanent solution and will not maintain lower nitrate levels on their own.

      Get rid of the excess algae. Just wiping down the walls of the aquarium can make a big difference in the nitrate levels. If you are not replacing your filter, at least rinse it out.

      Introduce some new neighbors to the aquarium. Tangs and gobies are hardy fish that love algae and will be happy to keep the waste materials and the green stuff to a minimum. Snails are also good for this job.
