Customers say
Customers find the water conditioner effective, with one mentioning it removes high levels of nitrite and nitrate, and another noting it keeps parameters perfectly in check. The product keeps goldfish alive and healthy, is easy to use, and customers consider it good value for money. However, several customers report issues with water clarity, describing it as very cloudy and white.

Works great, happy, healthy fish.
We’ve had issues with our goldfish dying off of disease with either new goldfish or newly introduced goldfish. We’ve been using this with our latest batch of goldfish and they’ve stayed alive and healthy longer than any other fish we’ve had.It works great and we’ll continue to use it forever, highly recommend!

Like it for my goldfish
Works well, but I wish it came in a larger size. I have a 20 gallon that it works well in. The last one I bought had a cracked cap so I had to recycle one from another bottle to make sure the liquid didn’t evaporate after I opened the seal.

This is a quality brand. I’ve had good results with all their products except the stress zyme, which stripped the colour off my shubunkins.

Bought these for my goldfish only tank and did not have any problems till nowIt is a bit expensive but worth it.A must for fancy goldfish varieties.

I’ve used this for almost 20 years now and having run out of it and bought another brand I was amazed at what it actually does for my fish. Needless to say I won’t buy another brand again. I mostly use stress coat and use this on an alternative rota with the stresscoat. I can only recommend it to anybody who cares for their fish. I keep fancies like Blackmoor, Orandas etc….although I have two corydoras living with my pensioners (my youngest is a 10 year old blackmoorð) since about 16 years and it certainly works for them as well. Absolutely no hesitation in recommending this and the API Stresscoat with Aloe Vera.

still not sure why my goldies got infected, first their bodies turned red-ish and creamy, then some turned upside down and some with scals, fins and tails peeling off, extremely sad to see them suffer the slow and painful death and couldn’t be able to save them
