API GOLDFISH PROTECT Aquarium Water Conditioner 118 ml Bottle

I think my gold fish likes this one. One of my goldfish was sick and I used this along with other treatment and it worked, now I am not sure if it was this one or the other product but either way it helped my gold fish. I use it every-time I change water (which is every other week).

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 blackmoor😉) 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.

It definitely does what it says. It keeps the water in the tank nice and clean ( in conjunction with the pump of course. Very easy to use. Definitely will buy again.

From my daughter: Small bottle, but very effective. It is lasting me a while and my little fish Hecta is swimming happily! Delivery took a while so next time I will buy in the shop (same brand though!) Good price and gives conversions on the bottle. (1 capful = 11 Litres) do recommend, only problem is the size, but it was shown in the description.!

Didn't see any difference!

simple, if I don't use it, my poor fish stay at the bottom of his tank looking all sick from the tap water of London, it's magic how much a difference it makes, a must have for your fish health.

Ever since I started using this I noticed a change in my fish, they are more active. Before I started using this they were swimming around then started resting on the gravel and stayed there for a while. The other water treatments I have used have never done this. I am going to continue using it.

Killed all my fish

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 now It is a bit expensive but worth it. A must for fancy goldfish varieties.

No issues so far. Keeps my fish tank water safe for my gold 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!

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
