This is a very good aquarium conditioner that I can recommend without reservation. I like that this does more than just dechlorinate. NovAqua calls its product a "bandage in a bottle" for fresh and salt water fishes, pond fish and invertebrates. It has the additives I recommend everyone use to help a fish make and preserve their essential slime coat and adds electrolytes to maintain a proper osmotic balance for gill function. It also removes toxic metals like copper, stabilizes pH and balances alkalinity.

The conditioner does not remove chloramines, but then, most chlorine conditioners don't either (Tetra Aqua's AquaSafe is an exception that does both). Kordon makes NovAqua, and they have a similar product called Amquel, which is specfic for chloramines. The two products can be used in conjunction if your municipal water supply adds chloramine (you will have to call them to check - you can't tell at home).

I would prefer the product come with a way to measure out larger dosages (rather than just drops), but I like that this product comes with an electrolyte enhancer.

The 8 fl oz bottle is a good price for the size and comes with an nice squeeze top. Since all you need is a drop per gallon, it lasts a good long time. You can use it whenever you add or change water, add new fish or toys, or if your fish are experiencing any stressful conditions.

Here is an easy Amazon link for the NovAqua water conditioner in the 8 oz size, and a link to the Amquel product, as well (if you have to deal with chloramines):
