API Pond Aqua Essential Pond Water Conditioner 1-Gallon Bottle

I use this every time I add fresh water to my pond. It's concentrated so it goes a long way. It's made for taking clorine out of the water. Makes the pond safe for fish.

I actually bought this for my 60-gallon tank so I only need to use around 6mL for each full water change which makes it last a really long time! I really like API products, they work well and are priced reasonably so I would definitely recommend it!

Fast ship great product

Also works good in large aquarium

Works well! Had unknown nitrate koi pond spike, cause unknown, used as directed and within 24 hours nitrates acceptable… saved my 4 yr old expensive koi, whewww, could have been disaster had I not had this on hand for emergencies!!!Have used in saltwater tank and when moving to larger tank and getting new tank regulated, never had unacceptable spike during transition..

Got this stuff for our pond and it works great. We have tried other products but this one really worked on our pond

This stuff is great!! I use it all the time, when changing water, adding water, or when I need it. I have never lost a fish since using this water conditioner. It is easy to use and is cost effective, because you use a small amount. We have very hard water that is treated with way too many products, and this conditioner seems to fix it, making it safe to use in the pond or the aquariums. I recommend it for using in ponds.

Use this when adding tap water to my koi pond. Use as directed.
