Aquarium Care: What is Old Tank Syndrome?
Old tank syndrome can be prevented by regular and frequent water changes. Test the PH of your tap water (you only need to once since it never changes) and then test the PH of your tanks.
Many fish keepers who face this problem are suffering from what is commonly referred to as "old tank syndrome". Old tank syndrome occurs when dissolved fish waste, leftover fish food, and decaying plant matter decompose in the water. The decomposing waste slowly softens the water and lowers the PH. In the amazon river, the PH is lower than that of local tap water. That is from all the decaying foliage on the bottom of the river. This kind of water sometimes starts to get a greenish/brownish tint and is often called "blackwater".
Oftentimes, when this phenomenon occurs, there are usually elevated levels of ammonia and nitrite from fish waste decomposing in the water. If you have a well planted fish tank with a small amount of fish, chances are you are not going to be seeing any ammonia or nitrite. Plants can absorb small amounts of ammonia, preventing nitrites from accumulating in the water, but if there are too many fish and not enough plants you aren't going to see a real difference.
If there isn't any ammonia or nitrite in the water, there shouldn't be any problems, right? Wrong. If a fish suddenly dies from illness or age a water change will be necessary. When you try to add new water, the PH will be much higher potentially sending your fish into shock.
Many fish stores do frequent water changes and their water parameters are near identical to that of tap water. This way, all the new fish they get in will be able to transfer into their tanks without any problems, and their fish can transfer to healthy tanks with no problems. When these fish are added to tanks suffering from old tank syndrome, the fish go into shock from the sudden PH change leading to their death.
Old tank syndrome can be prevented by regular and frequent water changes. Test the PH of your tap water (you only need to once since it never changes) and then test the PH of your tanks. Once your PH has lowered, you know your water change is past due. The water changes should be done before either ammonia rises or before the PH lowers (whichever comes first). Tanks with more fish need more frequent water changes than those with less fish.
If your tank already has old tank syndrome and the PH is lower than that of your tap, do NOT fix it right away. If you bump the PH back up to that of your tap water right away, the fish can go into shock. Slowly start increasing the frequency of your water changes to slowly bring the PH back up. Avoid larger water changes, and do more frequent small water changes.
