Goldfish aquarium water change10/6/2023 ![]() Smaller aquariums can do with a simple HOB or sponge filter which barely cost a thing. ![]() So do your fish and yourself a favor, and don’t skimp on the aquarium filter. I’d recommend no more than 30% of the total biological media.Īquarium filters are an invaluable piece of equipment when it comes to maintaining stable water parameters.Įven though you can harbor live fish without one, doing so is extremely difficult and requires advanced fish keeping knowledge. The only time you should change water is if there’s a following inexplicable spike in Nitrite.īear in mind that borrowing too much media could impede your established tank’s cycle. I’m sure you already figured that but here it is anyway- supply yourself with the bacteria first, so you can add it immediately after the initial water change from step number one.Īvoid changing the water for the next couple of days to let the bacteria establish themselves. It is beneficial bacteria and it won’t do harm to your fish. If you do end up in the fish store make sure to get a bottle that’s as manufactured as recently as possible.Īmazon supplies are usually fresh, but in some cases, you may get lucky in your LFS as well.ĭose accordingly, but in my experience, you should pour the whole bottle in anything larger than 30 gallons. Look it up online (you can check it out here, on Amazon) or rush to your local fish store and buy it, as soon as you have the chance. In the link, I also include the correct ways to use them.įor the purpose of controlling nitrites, I strongly recommend using Tetra’s SafeStart Plus.įrom what I’ve found, it arguably has more nitrite-converting bacteria than API’s Quick Start product. I also did a detailed comparison between two of them here, and namely Tetra SafeStart and API Quick Start. Luckily, after conducting my own experiments, I found four sound products that do actually work as marketed. These land-based organisms will essentially outcompete the not-well-established aquatic bacteria and then die out in underwater conditions.Īnd then you’ll be left with another spike in nitrites and no one to handle that. Most of them are complete garbage, however, the reason being the use of cheap-grown land-based nitrifying bacteria. There are many bottled bacteria products on the market. One of the most efficient ways to quickly add beneficial bacteria to your tank is by using bottled bacteria. If your ammonia tests show 0 ppm, but your nitrites are high your fish tank lacks nitrite-oxidizing organisms. Since high nitrite levels are signaling an incomplete nitrogen cycle, adding some good bacteria to the system should be your second course of action. This can send you fish into an osmotic shock, which is the last thing your fishpals need.Īuthor’s note: Water changes can also help with reducing high Ammonia levels in your fish tank. However, by performing a large water change you significantly alter the water chemistry in a short matter of time. ![]() This way you’ll make sure that the drastic shift in parameters that comes after a larger water change won’t finish off your fish.įish can adapt to gradual changes in their environment, including an increase in nitrites. I recommend splitting the 30% into two partial water changes of 15% and performing them 1 to 2 hours apart. With this initial step, you aim to replace part of the nitrite-rich water and dilute the harmful compound in the tank.īy physically diluting the concentration you will ease the negative effects on your livestock. To promptly lower the high nitrite levels in your freshwater aquarium follow these exact steps: 1. They can be lethal to most freshwater fish if not handled on time. Nitrites are the second most toxic byproduct in the nitrogen cycle of an aquarium. How to promptly lower the nitrite levels in your freshwater aquarium? With that out of the way, we can answer the important questions.
