Does it remove chloramine or only chlorine?

It removes chlorine and breaks the chlorine-ammonia bond in chloramine. The ammonia is left in the water for your biofilter to process, so a cycled tank matters.

How much water does one bottle treat?

The 32 fl oz bottle treats about 1,920 gallons at the standard dose. That is roughly 38 typical 50-gallon water changes.

Is it safe for saltwater and reef tanks?

API lists it for both fresh and saltwater aquariums. It contains no slime coat additives, but dose to the volume of water changed, not the whole tank.

Should I use it when adding new fish?

Yes. API instructs dosing at tank setup, during water changes and when adding fish. It neutralizes tap chlorine that would otherwise harm gills.

Is it better than a stress coat conditioner?

It is a plain dechlorinator; stress coat products add slime coat ingredients. Choose this if you only need chlorine and chloramine removal, and a stress formula if fish are injured or shipping.

Large bottles like this one usually cost the least per gallon. Watch for multi-packs and subscribe-and-save discounts, since the liquid has a long shelf life.

Our take on the API Tap Water Conditioner

API Tap Water Conditioner is a dechlorinator for freshwater and saltwater aquariums. One dose removes chlorine and breaks the chlorine-ammonia bond in chloramine, leaving ammonia for the biofilter to handle. It is a single-step liquid, so it suits routine water changes and tank setup. The 32 fl oz bottle treats roughly 1,920 gallons, which makes it a long-lasting staple rather than a specialty fix.
