What pH Level Should Guppies Be Kept In?

Despite their small size, Guppies demand a lot of attention. You’ll need to replicate their natural environment to provide them enough room to live. Maintaining a suitable guppy pH level in the tank will help in this situation.

Does the pH of the water have an effect on guppies? Are they affected by changes in pH? Will guppy fish perish if the pH level is too low or too high? Guppies are tough fish that can survive in a broad variety of pH values. However, keeping them in basic water with a pH of 7 to 8 is the ideal option. Guppies and other livebearers dislike soft acidic water.

The scale which tells us about how acidic, neutral, or alkaline is the water of our aquarium is called pH level. The range of pH is 0-14. The best pH level for guppies in which they live happy, healthy and reproduce is 7.

So, if you want to learn more about the pH level of water and how to preserve it, you should read on. We’ve gone over everything in depth here for your convenience.

How do you Determine the pH Level of Water?

It’s not difficult to determine the pH of water. A pH tester strip or a digital pH meter is required to determine the pH level. Although it is more expensive than the strips, I prefer to use the digital pH tester. Because strips expire after a certain amount of time and no longer produce accurate results, the digital tester may be a better long-term option.

The ideal pH and Water Hardness

What is the Appropriate pH for Guppies?

Guppies like water that is an identical copy of their native environment, with a hardness of 8 to 12 dGH. The pH level of guppy water should be between 6.8 and 7.8. Keep in mind, however, that water hardness and pH levels are linked; the higher the hardness, the higher the pH levels.

Why is it Important to Keep the pH of my Guppy Tank at a Certain Level?

Guppies are quick to adjust to changes in their surroundings. However, people must feel at ease in order to be truly comfortable. However, as adaptable as they are to a wide variety of pH values, they, too, have limits.

Guppies will eventually develop an unhealthy environment because of frequent pH swings and unsanitary living conditions, which will have a significant influence on their fundamental biological functioning. That’s where the appropriate pH level for guppy comes into play.

When Should You Check the Water pH Level?

It is better that you check the pH level of your tank frequently, most preferably, once in two weeks should be done. The kit will produce various results depending on when you test. So, to acquire more reliable readings, analyze the water in the afternoon. If you want to add other plants or objects to the tank, check the pH level after you’ve put them in to make sure the water is still acceptable for the guppies.

When Should You Check The Water pH Level

What is the Best Way to Lower the pH Level?

If the pH level of the tap water in your aquarium is higher than 8, you should try decreasing it. You have a few choices for lowering the pH level of your tap water. Keeping water in open bottles or buckets for a few days is a smart way to reduce the pH level. I’ve seen that the pH level of aerated water may decline from 8.5 to 8 or lower in only a few days.

If you don’t have access to liters of water, live plants can be used in your aquarium. Live plants are loved by guppies and fish, so use them with confidence. Plants assist to keep pH levels in check. Water in aquariums with real plants has a lower pH than water in tanks with plastic or no decor.  Chemicals can be used to reduce the pH level. Reduce pH levels by adding 2-3 drops of Seachem Prime to each gallon of water. Prime is an excellent solution for removing chlorine, chloramine, and other heavy metals from tap water.

Driftwood may also assist to reduce the pH level in your aquarium. Injecting CO2 into planted aquariums lowers the pH of the water in the aquarium.

The pH of RO/DI water is 6. The pH level can be lowered by mixing tap water with RO/DI water. Slowly add RO water to tap water and thoroughly mix it up. Before putting it in your aquarium, check the pH level and adjust the temperature. To create RO/DI water, you’ll need to invest in a RO/DI water system.

When Your pH is Too Low, What Happens?

A guppy will not die if the pH is too low, but it will live for a shorter period of time. Simply said, this species can survive in low water conditions, but it will not live a long and happy life. As the guppy’s pH drops, the water becomes increasingly acidic, eventually becoming lethal. The toxicity upsets the chemical balance of the water, exposing their little bodies to bacteria and other ailments.

What Could be Causing the Drop-In pH Levels?

Ammonia will build up in the tank if you don’t clean it, refill the water, or wipe it. The longer the aquarium is unclean, the more ammonia will build up, drastically lowering the pH. Another element to consider is the new water you’re attempting to add to the tank. You run the danger of the pH level decreasing if you just dump it in.

What Can I do to Increase my pH Level?

Low pH values in freshwater aquariums are unusual, although they do happen. Consider the following options to raise the pH level in your aquarium:

The pH of aquarium water may be raised by adding 1 teaspoon of baking soda to every 5 gallons. Before beginning to dissolve the baking soda, remove the fish from the tank. After 30-60 minutes, reintroduce the fish to the aquarium. Check the pH level once more before adding the fish.

The substrate can also help to reduce the pH level. Remove the old substrate and replace it with Texas-sourced coral, limestone, or holey rock. This collection’s minerals and rocks will help to raise pH levels. Keep fish away from the substrate when working with it since it may be unpleasant to them. Check the pH level of your aquarium once a week and test the results.

What Can I Do to Increase My pH Level

Adding 1-2 seashells to a gallon of water can also help to improve the pH level. Seashells contain carbonates, which dissolve slowly in water and assist to raise pH levels. Seashells may be found at most pet stores as well as on Amazon. Do not use seashells that have been painted or that have been used for house decoration. These may include substances that are harmful to your guppy.

Consider removing any driftwood from your aquarium to see if it’s causing the pH level to decrease. This is frequently a viable option. The pH of aquarium water tends to decline over time. If you have living plants and are infusing CO2, the pH level will drop more quickly. Maintaining proper pH levels may be as simple as changing the water on a regular basis.

The pH level in your aquarium will also be raised by aquarium salt. It will also raise salt levels, which certain freshwater fish cannot survive. Guppies, fortunately, can tolerate a modest amount of salt. Some disorders, such as ich or other bacterial infections, can be treated with salt. Per gallon, add 1 tsp aquarium salt. Iodized or table salt should not be used.

When the pH Level is Too High, What Happens?

Guppies are unconcerned with high pH levels. However, if the levels are really high, they will begin to influence the water chemistry. An alkaline atmosphere is created by high pH values. The more time the guppies are exposed to alkalinity, the more health issues they will acquire.

The water will eventually erode their mucus or protective skin covering, exposing them to illness and pathogens. The germs will eventually permeate the system and develop into an illness, reducing their chances of life.

What Could be Causing the Increase in pH Levels?

Chemicals and gas exchange are two elements that might cause the levels to rise. Chemicals, sometimes known as contaminants, accumulate over time. The gas exchange, on the other hand, occurs when we open the aquarium and allow airborne oxygen to enter while carbon dioxide (CO2) escapes into the atmosphere. The pH levels rise as the CO2 evaporates.

The Bottom Line on What pH Level Should Guppies Be Kept In?

Maintaining proper pH levels for your guppies will guarantee that they live in a healthy and comfortable environment. Even while maintaining an ideal pH level might be tough, there are a variety of strategies you can take to overcome these challenges. You will always discover the ideal technique that will compliment your guppy’s surroundings if you experiment with your options—making some easy modifications to your tank cleaning routine to achieve that.
