How To Make Tap Water Safe For Fish Without Conditioner

One of the essential living parameters for fishes is the water condition of the tank. The water condition of an aquarium can go a long way in determining how healthy your fishes will be and how well they will thrive. To make tap water suitable for fish aquariums, people often use different methods like adding conditioner to it. The chemicals found in these conditioners are not too good for the health of aquarium fishes, hence a need for an alternative.

Make Tap Water Safe For Fish Without Conditioner

Several methods are used as an alternative for conditioners in treating the water used for aquariums. You can make tap water safe for fish without conditioners by making use of alternative means such as reverse osmosis system, electromagnetic and electromagnetic water treatment; template-assisted crystallization, as well as electronic water condition. You can also leave tap water to sit for about 26-28 hours before aerating it.

This alternative method of water treatment can prevent your fish from being exposed to harmful chemicals aside from making the water suitable for them. Although some of these methods are quite technical, they are quite active and relatively safe. It might also be a little more expensive, but it’s worth it after all.

Is It Important To Use Conditioner For Tap Water In Aquarium?

People often say conditioner is vital to make tap water safe for fish because it helps in treating the water. Tap water is considered unsafe for fish because they contain chlorine and some heavy metals that might harm the fishes. It can also soften the water to keep it ideal for fish to thrive.

However, there are much more to keeping a fish alive in the aquarium than just adding conditioner to tap water. Although aquarium owners should not use tap water without any treatment, you can employ alternative means of water treatment. It would help if you also made the water germ-free to protect your fishes.

Some conditioners used to contain chemicals that are harmful to the survival of fish in the tank. To be precise, most chlorine-based disinfectants are detrimental to fish. They are capable of damaging the gills and skin surface of the fish, which is as bad as the untreated tap water itself.

Exposure of fish to a high level of chlorine-based disinfectants and other harmful chemicals can let them show signs of irritation, erratic swimming, and making repeated attempt to jump out of the talk. However, the chemicals might not be so life-threatening at lower concentrations.

In summary, the important thing is not using conditioners; the important thing is making the tap water safe for fish. You can employ alternative means that do not involve the use of chemicals for treatment of tap waters to make it suitable for fish. You can let water sit and vigorously aerate it for 26-48 hours to drive off the chlorine gas. Also, you can use methods like the reverse osmosis system, template-assisted crystallization, electromagnetic water treatment, and other related non-chemical means.

Reverse Osmosis System Of Making Tap Water Safe For Fish

Reverse osmosis system is one of the most reliable non-chemical based methods of making tap water suitable for fish. It can remove up to 99% of all dissolved solids in water. This method can even make water suitable for human consumption. Reverse osmosis system is also capable of removing impurities and other chemicals like fluoride and chlorine from water.

This ability to remove fluoride, chlorine and some other chemicals from water is why it is considered an excellent alternative for conditioners. Also, reverse osmosis does not require too much energy, so you don’t have to worry about power consumption. Nevertheless, it is still relatively more expensive than conventional conditioners.

Aside from getting rid of dissolved particles and chemicals from water, a reverse osmosis system is also capable of improving the appearance, taste, and odor of water. You can also use more than one filter to enhance the effectiveness of the reverse osmosis system. But before doing so, you should be aware that the more filters you have, the more expensive the system.

Overall, reverse osmosis is a speedy process that is easy to maintain. It is also a long term system that can provide a solution to your water treatment problems year in, year out. However, you should carry out regular maintenance on the network to prevent mould or mildew from growing in it.

Proper Water Parameters For Fishes

Individual fish type might have different environmental demands and can thrive better under different water conditions. The aquatic environment of aquarium fish includes a freshwater aquarium, brackish waters aquariums, and ponds.

The freshwater parameters of an aquarium are slightly different from the salty water parameters. Therefore, it is essential to configure your water parameters to suit the type of fish in your aquarium.

In general, the freshwater parameters can include a pH of 6.5-7.5 with zero ammonia level. Likewise, the temperature should be kept in the range of 72-86°F depending on the specific nature of your fish. The general hardness of the water should be at a moderate level, and the nitrate level should be below 50ppm.

Marine water parameters can be relatively more demanding. It is essential to keep a specific gravity range of 1.20-1.25, and the pH must be between 8.1-8.5 as well. The temperature must be between 72-82°F depending on the particular demand of the fish. The calcium, magnesium, iodine, and strontium level of the water should also be in check. It is also a point to note that the ammonia level of marine water is mostly undetectable; and if detected, it should be at a near-zero level.


The most important thing to consider in using tap water for fish is not if you should use a conditioner or not. It is more important to focus on the safety of the water for your fish. The alternative water treatment methods to conditioner are generally safer because it is not chemical-based. Exposure of your fish to a high level of chemicals can yield detrimental effects like irritation of skin surface and gills.
