Questions & Answers

what is the risk if I pour more of what I need ?
Answer by ChewyJun 30, 2017
You can safely dose 2-3 times the directed amounts to neutralize higher levels of chlorine, or chloramines. If you accidentally add more treatment, a partial water change should be completed.

I purchased API Quick Start...do I still need to use this tap water conditioner along with Quick Start or just one is needed?
Answer by ChewyOct 09, 2018
Quick Start should be added to dechlorinated water, otherwise the chlorine can harm the beneficial bacteria it contains, as well as the fish you are trying to keep. It is recommended to treat the water first with API Tap Water Conditioner before adding new water to the tank, to remove the chlorine and chloramines. The Quick Start would then be added directly to the aquarium. Quick Start contains only the live bacteria -- it does not contain a dechlorinator, so both are necessary for a happy and healthy aquarium.

How long do you have to wait to put the fish back in after using the water conditioner?
Answer by ChewyMay 10, 2019
The API Tap Water Conditioner removes toxins instantly, so you can add fish to your aquarium (or add them back after a water change) immediately.

how many onzes do I need for a 2000 gallons of water ?
Answer by ChewyJun 04, 2019
It's recommended when removing chlorine and detoxify heavy metals to add: 1 mL for each 20 U.S. gallons (76 L) of aquarium water. To detoxify chloramines: add 5 mL for each 30 U.S. gallons (114 L) of aquarium water.

No way to test Tap water conditioner.

I purchased this because my daughter says that it is suppose to work. We have city water and all of the cocktails of chemicals. I have no way of knowing if it works because I don’t have a test kit to determine.

Does the job

I have been using API Tap Water Conditioner for years and have never had a problem. It does everything the more expensive water conditioners do, but at a fraction of the cost. Spend money on the fish you want and not water conditioners.

Works as intended

Works great ! Usually I add more than intended as my state adds ammonia to the tap water, but since this is super strength formula, I don’t ! Recommend this if your state does the same ! It wastes less product !

must condition tap water

You need a water conditioner to remove chemicals from your tap water if you keep tropical fish or gold fish.

Water Conditioner

Good price for the amount you get. Arrived quickly. Only concern is that Chewy's instructions for dosing is different from what's on the label.

Water for plants

I use it to prep tap water for use on all my indoor plants, especially the jewel orchids. Previously used the API heavy metal neutralizer for my small fish pond with plants. Same effect, may the same product? Either way, both seem to work well, fish and plant are thriving.
