Useful aquarium water conditioner.
I am pleased with my purchase as it seems to be working very well. This product is a water conditioner and makes tap water safe for aquarium fish removing any harmful chemicals. Also replaces fishes coat if damaged by handling or fish fighting etc.

Great for houseplants too!
I have been adding this to my watering can every time I water my house plants for a few months now and I have noticed that my sulky peace lily has fewer and fewer brown and yellow edges to it’s leaves. I have had this plant for years and the new growth is lush and green. I have noticed that new plants watered with this in the water have not had any discoloured leaves, so as far as I am concerned it is working well for my purposes.

Bought for houseplants
Bought to neutralise chlorine for houseplants. I think it’s made a difference, plants are greener and I’ve finally managed to get an orchid to rebloom. Brother swears by it for his aquarium also.

Not Just for Fish! Also Great for Plants!
I don't use this for an aquarium. In fact, I don't even have an aquarium. It was recommended by a plant expert to use in the water I use to water my plants. Hard, chlorinated water filed with chemicals is not good at all for plants and while it won't kill most of them, some of them end up unhappy over time. When I first heard about this product, I was skeptical. Could it really help with my plants? Well, upon researching, apparently so! It removes not only chlorine, which is in all tap water, it removes chloramines and heavy metals. They're all bad for fish and bad for plants as well! The price is low and I use just 2 - 3 drops with each gallon of tap water, immediately takes action. No waiting! I bought the 4 ounce size and at this concentrate, that much will last me years (and I have a lot of house plants. There's not much odor, it's clear and a little thicker than water. This is a no-brainer. I'm happy I discovered it.
