Review on Tetra Aquarium Algae Control - Broad Spectrum Algae Control Solution (3.38 Oz) by Karina Miller

We highly recommend this product! My aquarium was very hazy green and looked horrible and this product cleaned it overnight. I woke up the next morning and everything was clear and looking great - a huge difference. I have some advice for other users. MAKE SURE YOUR FISH DON'T ATTEMPT TO EAT THE DROPS THEY GET! My fish have a fairly regular feeding schedule so every morning when I feed the fish they usually start attacking the surface where I drop the food. When I wanted to apply this anti-algae liquid - I put a few drops in the aquarium - one of the fish immediately thought it was food and tried to eat the drops. This fish died a few hours later, apparently after swallowing a concentrated drop of liquid. NOT GOOD. Can I blame this product? NO, because all my other fish were fine, but that's clearly something to be aware of. Make sure you are not near the fish when adding the drops to the tank, or stir the tank immediately or place the drops in a filter for better distribution. This will kill your fish if they eat it.
