1.0 out of 5 stars Used half dose for 3 days, it killed half my fish
Reviewed in the United States on July 30, 2023

In a 100 gallon aquarium some tetras from Petsmart gave the tank ich. Since I have plecos and corydoras I used half dose as directed. Removed carbon filters, then 50 drops into 100 gallons.
Within hours the fish were clearly in distress, staying still and up near the surface. I checked dissolved oxygen and it was perfect at 7.8mg/L. By the next morning several neon tetras were dead and the rest looked totally stressed and likely to die. By treatment day 3 all neon and glowlight tetras were dead. Two corydoras and a German ram also died.

I still see ick on a few of the surviving fish, but less than when I started treatment. Hopefully day 4 will see it completely gone. But I'm not happy stressing fish to the point of losing half of them just to treat ich. There has to be a better way.

Purchased this as a pleco in my quarantine tank developed ich. I was a bit worried on how this treatment would affect him, as well as several cory's that were also quarantining in the same tank as most ich treatments are harmful to scaleless fish.
I ended up treating 3 rounds (3x 3 days of treatment + one day break in-between) consecutively and noticed the ich was gone on day 5. I continued treatment as there didn't seem to be any ill affect on the pleco, cory's, or honey gouramis and I wanted to make sure to kill the ich during the vulnerable stage of its lifecycle. During this time I had also raised the temperature to 30 degrees Celsius and added extra aeration to the tank. Each day of treatment I also preformed a 25% water change before adding more treatment, making sure to syphon the gravel well.
As of now, its been more than 2 weeks since the pleco showed any signs of ick, and none of my other fish ever developed symptoms'. Not sure if it was the combination of water changes + temperature + this treatment or if it was one or the other but it seemed to work!
Only downside is its very hard to add "one drop per gallon" as the dropper does not work very well, and often collects multiple drops before dropping--or squeeze's out too fast/much.
My fish were quarantining in a 10 gallon tank, so each day I aimed to add 5 drops (half dose for plecos and cory's), but I upped it to six for the last round of treatment. However, with the dropper being how it was, I'm sure there was more drops than I had intended.
This also did not seem to have any affect on an anubias and some subwassertang that I had in the tank. However, I would be hesitant to use it in my main tank which is heavily planted, but hopefully I never need to!

5.0 out of 5 stars Works but difficult to dose
Reviewed in Canada on August 6, 2023

I have ten neon tetras in a planted ten gallon that came down with a couple spots of ich. The directions indicated a half dose for more sensitive fish (including tetras), so I half-dosed for three days, paused one, and dosed for one more and now the ich is gone! It's been three days since, they are all eating well and very fat showing no symptoms. No visible impact on my plants either.

I like how it comes in a bottle so you can have it on standby for future ich cases. All in all I used 20 drops to treat my ich, so the bottle is still practically full. I don't see myself running out anytime soon, so it's nice to have the remainder as a back up.

My only complaint is that the drip feature built into the bottle is messy - sometimes when you try to squeeze out one drop, you get two as the liquid tends to hang on lip of the bottle. I just let it hang and give it a whack against the tank to dislodge it. This isn't ideal when trying to dose for sensitive fish or prevent messes, as this stuff stains blue... and my tank sits on a wooden desk. Keep a tissue nearby when dosing!

5.0 out of 5 stars This stuff saved my pond.
Reviewed in Canada on June 23, 2023

Noticed white spot/ich on my goldfish in our 7000-gallon pond. Ordered several bottles of this product, as it's one of the few treatments available in Canada. I would have preferred larger bottles to save on cost, but larger bottles wouldn't have arrived in time save the pond, so I had to make do. All told, I needed 11 bottles to fully dose my large pond for the prescribed three days (3.5 bottles per day, based on the volume of my pond and the listed dosage). Noticed visible reduction of ich within a day of the first treatment - some fish went from completely covered, to just the fins and tail showing signs of infection. Within three days of treatment, the ich was gone from all affected fish. Catching it as early as I did was key, based on descriptions of how ich develops - but there is no doubt that this product works. Will definitely be keeping a larger bottle on-hand at all times in case it recurs in the future. Absolutely recommended.

Note - since this product contains a dye to help treat ich, it does stain skin blue for a couple days on accidental contact. I imagine it would do the same to untreated wood and possibly porous stone, so be careful if applying outdoors around ornamental rocks or wood.
