In order to make sure that your fish is healthy, you need to treat the normal tap water so that it suits their needs.
Since tap water has been treated for human consumption and use, it contains numerous chloramines, chemicals, and heavy metals that can cause your fish some real harm.So, what should you do?You can start by treating the regular tap water using a good aquarium water conditioner which helps neutralize the chloramines, removes chlorine and essentially detoxifies the water.In this article, I’ll go through the best aquarium water conditioners for your Goldfish.
Let’s get started, shall we?
How Tap Water Conditioners Work
Did you know that normal tap water is like poison for your goldfish?
Chlorine, along with some other chemicals used to process water can burn your fish’s gills and these invisible materials can attack your fish’s living tissue which, over time, can cause breathing problems for your your goldfish.So, removing chlorine from the water is extremely important—or it can prove to be fatal.
The thing is that chlorine isn’t the only culprit here. Water districts have different standards to process water and make it safe for human consumption.
These chemicals include chloramine, chlorine, etc. which are dangerous for your goldfish.
Some public water systems also disinfect water by adding chloramine to it and that may require you to get a water conditioner that works by splitting the chlorine-ammonia bond and then neutralize each separately.
I feel that that’s why water conditioners are important.
Still, don’t understand what the fuss is about?
The task of a tap water conditioner is to add negatively charged ions to the water which attracts disinfectants to itself. Now, the positively charged chlorine ‘magnets’ stick to these negatively charged ones instead of your goldfish’s gills.
Tap water conditioners do the job by basically neutralizing the chlorine in the water by forming ionic bonds which basically renders the chlorine harmless—this simple process makes tap water safe for goldfish and nourishes the beneficial bacteria that help in keeping your aquarium healthy.
Well, to put into simple words, the treated tap water is basically full to the brim with chlorine ions that are charged positively and act as magnets that stick to your goldfish’s gills.And, this process neutralizes the water and renders the chlorine harmless.
Your Tap Water Conditioner Options
As I mentioned before, all water conditioners don’t serve the same purpose.
Some work well to neutralize just chlorine, with others work well by neutralizing chloramine—while some act as an all-in-one solution to all of your problems.So, there are three main types of water conditioners that you should be looking out for:
- Dechlorinators: These conditioners contain small quantities of sodium thiosulfate which help in removing chlorine effectively and quickly from the tap water. However, they don’t work on heavy metals.
- Chloramine Neutralizers: These water conditioners are good at dealing with chlorine and prove to be a good solution for heavy metals as well as ammonia.
- Complete Conditioners: These water conditioners help combat chlorine as well as ammonia and are also good at detoxifying heavy metals and removing copper from the tap water.
Some water conditioners also contain added vitamins that help boost your fish’s immune system and also help replenish the fish’s slime coat which provides the fish with an extra layer of defense against diseases.
Water conditioners generally last a long time and aren’t too expensive.
