## Customer Reviews

### ⭐⭐⭐⭐⭐ Good
*by A***N on 20 June 2025*

Seemed to work well tank cycled quicker

### ⭐⭐⭐⭐⭐ Maintain a healthy Aquarium
*by M***D on 3 April 2021*

I use this product when setting up a new aquarium (as part of the nitrogen cycle to promote healthy ammonia eating bacteria growth, a 6 to 8 week process) and as part of my weekly water changes. I feel that this product works very well, as my fish are all happy and healthy and I have never experienced any bad water quality issues (ammonia spikes etc).I use this weekly to add to my 200ltr, 60ltr and 30ltr aquariums when I do a water change. I change 20% - 30% of the water volume and add an appropriate dose of this stuff, however it's not really possible to overdose so it does not really matter if you add a little bit extra. I usually do add a bit more than stated on the label. I keep it stored at room temperature and the 2ltr bottle usually lasts me about 6 weeks.There is always a seal covering the opening after the lid has been unscrewed, so you know it is brand new and has not been opened / tampered with. This is safe for my fresh water aquarium inhabitants, of which I have many varieties.Pros:- The larger 2ltr bottle is excellent value compared to the 250ml or 500ml bottles- Quick delivery / repeat orders available- Far cheaper than my local pet storeCons:- Nothing I can think of reallyI hope this review has been helpful to you.Happy Fish Keeping!

### ⭐⭐⭐⭐⭐ A Useful Product.
*by M***D on 2 May 2024*

I initially purchased this product to aid the initial set up of my aquarium which , I am glad to say, went without a hitch. The label on the product recommended that it be used at every water change and filter clean to maintain a healthy tank and fish population. I carried out that advice and use this product regularly. My tank remains clean and my fish remain healthy and active. I can only assume this is due, in part at leatss, to the continued use of this product. I will purchase it again in the future.
