Made all my tropical fish pass out. Luckily I quickly switched them to another bucket of water quickly and they come back to life, for how long time will only tell. One did die immediately. Poisonous product for your tropical fish.

This product helps to keep fungal diseases at bay. A little drop goes a long way and when regularly used keeps the fish nice and healthy.

Please take my advice and do not buy this product for your tank. I was recommended by a staff member to purchase this treatment and I wish that I went with my gut and didn't bother. This treatment reacted badly to my goldfish within 10 minutes of adding it to the tank. Within those 10 minutes my goldfish was swimming very oddly and erratically. A day later and my goldfish was left essentially paralysed. I have done countless numbers of water changes and added the carbon back into my filter to try and rid any trace of it from my tank but unfortunately the damage has been done. It has now been 7 days and my goldfish has not eaten, is lying at the bottom on the tank on its side where it has been for the last several days, is breathing slow and shallow, and I really don't think the goldfish is going to make it through the rest of this evening. It has been very distressing to watch. The fact that Pets At Home are still selling this product after seeing so many unhappy customer reviews on this page is unacceptable. This product has caused unnecessary suffering to my goldfish which again is unacceptable for any pet store. And just in case you were wondering, I followed the dosage instructions to the absolute letter as I would do with any treatment, so this disaster is all on Pets At Homes head. Take my advice and please do not buy and spend a bit more money on a product that will not kill your fish or cause unnecessary suffering.

Within 10 minutes all my fish were less active I did a emergency water change and there were fine after Can't believe this stuff is still on the market!

put in my tank as per the instructions to treat my betta fish. paralysed my fish? caused immediate stress. had to do an emergency water change to restore fish health- no idea what damage has been caused just praying it hasn't done irreversible harm!! sold with very little guidance!!
