Hikari Usa AHK73256 Prazipro for Aquarium, 16-Ounce

Good product for controlling pond algae.

This was one of two products we used. Could not use them at the same time. But, both worked well, and issue was brought under control. The trick was to use the right amount of the product (not too much), and do it as often as allowed for a duration of about 2 weeks. Follow the directions over what I say here, however, as I wouldn't want a failure due to someone trying to do it the way I did. I'd buy it again, and recommend it to others

I use this in my hospital tank. It takes care of almost any issue. I even used it once in my reef tank because i didnt really have a choice. Some of my corals closed up after dosing but oppened back up shortly after without any ill effects. I do not reccomend using anything like this in your reef tank unless there is just no other choice though but keep it around for your hospital tank.

Works good it just makes the water cloudy.

Works as intended. Mixes well in water and works fast.

It’s very efficient for parasites, and most importantly it won’t hurt the beneficial bacteria, even the most delicate fish will not be harmed by this medicine as long as you don’t over dose.

The best . Always make sure i keep it on hand, great for fish quarantine.

It took a few uses but I am finally free of that shrimp parasite that wiggles around on their heads. Months later and no sign of infection.
