What are the correct water parameters for platy fish? This is a question that many people ask, and it can be difficult to answer. There isn’t one set of ideal water parameters but rather a range of factors that need to be considered before we can come up with an answer. So what are the ideal water parameters for Platy fish?
Your tank must have the right pH level (7-8), hardness (5 or more dGH), temperature (72 or higher), salinity (1.003-3%), ammonia/nitrites/nitrates (.25ppm or less), oxygen levels, and removing tannins. You should also maintain the proper water changes for your tank to ensure that you do not take too much from or add too much to your aquarium.
In addition, Platy fish must have many plants in their environment as this will help maintain ideal conditions and keep them healthy so they can grow and develop. You should also consider the number of fish you have in your tank, impacting water conditions.
All these things need to be considered when trying to maintain ideal water parameters for Platy fish but, don’t worry if you are not able to do it yourself or aren’t sure how because many fish stores will do it for you.
This blog post will cover what you need to know about water chemistry for Platy fish and some tips on how to maintain those conditions properly.
Ideal Water Chemistry For Platy Fish: What Are The Correct/Ideal Water Parameters For Platy Fish?
Let’s discuss the chemical composition of water that is ideal for Platy fish.
Hardness
Ideal water hardness is around 150 ppm. However, it can survive in extremes of soft to hard waters. If you are not sure whether your tap water has a high or low level of hardness, test the pH levels, and if they are below seven, the water is very soft. If you do not have access to a kit or can’t test your tap water on your own, look for other sources of information about what hardness levels it might be (e.g., if there are any fish stores in your area that sell Platy fish).
pH
The ideal water pH for Platy fish is between seven and eight. If you can’t find out the hard levels of your tap water, do a Google search to see what other people in your area are saying about their own tap waters (e.g., “what’s the average pH level of Portland Oregon’s tap water?”). In general, if your water pH levels are below seven, your fish will become sick and die. On the other hand, if it’s above eight, you’re going to have a hard time controlling algae growth in the tank (and maintaining good plant life).
Water Temperature
It would help if your platy had tropical temperatures between 65-75 degrees Fahrenheit or 18-24 Celsius. Higher than this will cause your fish to become sick and die.
Salinity
This is a tricky one because few variables can change salt levels in an aquarium. One of those things is the type of substrate you have on the bottom of your tank (i.e., sand vs. gravel). Aquariums with fine-grained sands will affect the salinity levels in your tank, and you need to adjust the salt content accordingly.
Ammonia, Nitrites, And Nitrates
All fish produce ammonia as a waste product of breaking down food (i.e., fish poop). You can test for high ammonia by checking out the color of your aquarium water; if it is cloudy or murky, there’s a good chance that your fish are producing too much ammonia, and it is poisoning them. In an ideal situation, you should have no detectable levels of ammonia in the tank.
Nitrites are produced when bacteria break down the ammonia from the fish poop (i.e., nitrification). You can test for high nitrite levels (which is also poisonous) by checking your water’s color; you have high nitrite levels if it has turned bright neon green.
Nitrates are produced when bacteria break down the ammonia and nitrites from fish poop (i.e., denitrification). You can test for high nitrogen levels in two ways: one way is to test the water’s pH, and if it is above seven, you probably have high nitrogen levels. Another way is by checking out your tank’s color; if your aquarium water has turned a deep green or neon blue, you also have high nitrates in your system.
Tannins
Tannins are a byproduct of decaying organic matter (e.g., leaves on the floor of your tank), and they turn your water very dark in color. They will also affect the pH levels, so if you have high tannin levels in your tank, you need to test for this; ideally, it should be around six.
How Do You Maintain Ideal Water Parameters For Your Platy Fish?
I know how scary it can get when you add a new fish to your tank and want it to thrive.
You have been researching the type of water they need but then realize there are so many different parameters for this specific fish. This can get overwhelming when trying to figure out everything at once! So here, I will try my best to break down what these parameters are and how to make sure your fish is thriving in the way it should be.
Maintain pH In Aquarium
It would help if you aimed for a pH level between six and eight (ideally around seven) for the best results. This is especially important if you have high tannin levels in your tank because it will impact how well plants grow and how much algae will grow.
Maintain Hardness
Hard water is perfect for your Platy fish because it helps them to digest their food and strengthens their immune system, among other things. These benefits may not be as pronounced if you have soft water in your tank, but they certainly won’t disappear altogether! To maintain the right hardness level, aim for two hundred to four-fifty parts per million (PPM).
Maintain Water Temperature
Platy fish are happiest at temperatures between sixty and eighty degrees Fahrenheit. If you have a water heater in your tank, this shouldn’t be too much of an issue, but if not, you must invest in one because Platy fish are tropical fish, which means that they need to be kept in the heated water time.
Salinity
Platy fish prefer brackish water with a salinity of around SG one (around fifty parts per thousand). To maintain this, you’ll need either an aquarium or fountain pump because the best way to introduce salt into your tank is to circulate it.
Remove Ammonia, Nitrites, And Nitrates
Ammonia and nitrite are extremely toxic for Platy fish, so you should have a filter that can remove them from the water regularly. You’ll also want to change some of the water in your tank at least once every two weeks or so to remove nitrates.
Maintain Oxygen Levels In Aquarium
Platy fish are susceptible to oxygen levels because they can suffocate if the concentration is too low for too long. This is why you need an air pump and airstone, but you also have to regularly monitor oxygen levels with a test kit to ensure that they’re high enough.
Do Platy Fish Need Tannins?
Tannin is a byproduct of decomposing plants. It can have some important benefits for your fish tank, including keeping the water pH from fluctuating too much and helping to reduce algae growth. If you want tannins in your water, you can add aquatic plants to your fish tank.
The benefits of tannin are debatable, and it may not be necessary for a home aquarium environment with easy access to clean tap water for changes between water changes.
Some platies are native to blackwater, tannin-stained rivers in which water level can vary dramatically from season to season. It may be that these fish evolved with access to temporary pools that quickly became eutrophic due to leaf litter and other debris.
It is thought that tannin-stained water might help protect them from parasites and bacteriologic infections, so it’s best to keep your platies in blackwater, low pH conditions if at all possible.
How Often Should You Change Water In Your Platy Fish Tank?
You should change your water once per week, but this will vary based on the size of your tank and how many fish you have in it. The more fish there are, or the larger they are relative to the volume of water in your aquarium, the more frequently you will need to change the water.
It would help if you did not overdo the water change. You should not change more than 30% of the water at one time. If you overdo it, then the fish will suffer from oxygen levels that are too low and ammonia levels that are too high.
The best way to remove old water is through a siphon tube or bucket rather than an expensive aquarium vacuum because vacuums can damage your aquarium.
Is Chlorine Useful For Platy Fish?
No, chlorine is harmful to fish. Instead, use an aquarium water conditioner after you have added tap water to the tank. Also, try using a natural source of tannins if your platies are still distressed by adding new tap water into their environment.
The effect of chlorine in platies tanks is debatable. Some hobbyists swear by its use, while others recommend against it because they believe chlorine can harm beneficial bacteria and cause excessive algae growth. The truth likely lies somewhere between Chlorine does not usually hurt your fish directly, but too much is not good.
FAQs
I have answered some of the most common questions below. However, if you have a question not answered here, please get in touch with me, and I will try to answer it or find an expert who can.
Can You Keep Platy Fish In Cold Water?
No, Platy Fish need a temperature of around 24-28 degrees Celsius. Platy fish are tropical animals, so keeping them in the cold water will lead to respiratory infections.
Do Platy Fish Prefer Dirty Water?
No, in the wild, Platy fish live in spotless water. However, if your tank is dirty, you should definitely change it regularly because this will reduce the risk of infections and disease among your other fish too.
Conclusion
In a nutshell, the ideal water parameters for Platy fish are pH of around seven (neutral) to eight and a half (alkaline); a hardness of three hundred ppm or less; temperatures between twenty-four and thirty degrees Celsius; and, finally, salinity levels at zero parts per thousand.
