I like this one because it’s just one drop/gallon. Makes it easy to add to fish tank. Most of the other brands have you pore it into the cap and are so many ml/gal which sometimes makes it hard when you only need it for smaller tanks. Sometimes I just add a few gallons and I put just 3 drops in. Easy and never had a problem and I’ve been using this stuff for years. Sometimes it’s hard to find as it’s out of stock. I used to be able to buy it in store but Amazon has been the only place I could buy it for many year for some strange reason.

On arrival it looked like a tiny bottle and I was disappointed. Then I read the dosage instructions and realised you only put very small amounts in each bucket of water to treat it, making this great value, even though it looks small.

The solution in here seems to work better than the other solution that I used to have from the pet store, even though the bottle is smaller I would purchase this again

In a drop bottle which is great cause I always pour too much out of the screw-on lid ones. Small but good value, since it will last a long time.

I tend to buy this product as it is a good make.With this size it comes with a measuring cap which is helpful to measure out the right amount.Would Reccomend this product as a reliable and fare price.
