Excellent Value
Fantastic value for money set and will keep my aquarium going for the rest of the year no doubt. Handy 'measuring caps' as well so you don't have to guess if its the correct dosage by how many drops you're putting in the water.

I found one of them clean the glass and at the same time is good for allergy fish
I thought I needed. But when I got home I read the instructions again, I found one of them clean the glass and at the same time is good for allergy fish. I made sure I will not use it for my fish. He has bottles in the cupboard and I still do not know what to do with them. Maybe it does not bother me and I will give it to you.

Happy turtle
Always perfect for my turtle, she gets a dodgy belly normally but this helps a lot. Im still not sure of the water capacity of the tank as its massive and my bucket doesnt have measures on it

Expensive but good
Although expensive but very good for my fishes.

I’ve kept fish for many years, and this is one product combo I recommend without hesitation. It does exactly what it claims to do. After running out for a while, I immediately saw the difference in my tank once I started using it again — clearer water, healthier fish, and an overall cleaner environment. If you care about your aquarium and want consistent, reliable results, this is a must-have. I give my word on that based on long-term experience. Your fish will benefit from it, and the improvement is noticeable fast.

Best product i find to destress fish coat their scales n fins to protect them before an issue. Only way id not buy this pack is if I was buying same product but bigger container

I bought these for a very stressful move that we had to make. The fish were transported for 7 hours and they all survived. I use this in my tank during each clean and my fish are doing really well.
