These products are so good! Very good overall, except for the cyanobacteria kit with bactofresh added, the cyanobacteria are still there and haven't even had a little effect!

I followed the operating procedure for breeding daphnia... Despite this, they died in less than 1 week despite the addition of purchased algae.

Hello, I have a 3m³ pond and after distributing the product, the water is still green and there are no results. After rereading the product description, it states that the cap should be left open to keep the bacteria alive. If the product had been in the bottle for a long time, that's why I have no results. I am disappointed especially since the price is significant.

Response from daphbio
Hello Mr. Mellerin,
We are sincerely sorry and surprised to learn that you have not obtained the expected results in your 3 m³ pond.
In order to better understand the situation and assist you effectively, could you please send us a photo of your setup to the following address: [email protected]? This will allow us to analyze your pond more precisely and advise you better on the use of the product.
Regarding storage, you should not leave the cap open. The bottle must remain tightly closed to best preserve the quality of the product. Can you let us know where you saw this information so we can verify it on our side?
Awaiting your response, we remain at your complete disposal.
Best regards,
The Daphbio team

After a week of the re-seeding complex, I don't see much improvement.... We'll see in the coming weeks what happens.

Unfortunately, the product has proven to be completely ineffective. I followed the recommendations to the letter, both for using the anti-cyan bottle and for the bacteria falcon by disconnecting the skimmer each time. The cyan are still there, I have recorded a wrinkling of the actinodiscus but I cannot definitively attribute the cause to the product in question. The fish have not experienced any discomfort.

Bottle containing only water and a few not very lively specimens. They died in 2 hours while the tank was perfectly set up. In short, a beautiful very expensive scam. ....

No effect on cyanobacteria, I then used the absolute black method, no light and aquarium covered for 7 days and 7 days later all the cyanobacteria had disappeared, I should have started there I wouldn't have lost 79.48€.

I am currently using the product so for now I can't say because I don't see anything significant (except that the zoobooster and microfauna booster smell like lemon... after that it might be normal)

Good evening, it has been an epic journey, 3 stars not for the products which are of quality, because I already see life, but more for the delivery which took more than 7 days, which is not your fault. I would surely recommend you, the unpredictability and laziness (delivery person) are everywhere. Otherwise, product and commercial service Daphbio are top-notch (response within the day and delivery tracking).

It's simply a scam of H2O water, really disappointed no results. I'll never be fooled again, moreover it's confirmed by a store that I greatly appreciate which argued to me the lack of credibility in all the products offered.

I have always been happy with your products for 3 years. The only downside is that I received my products 24 hours late, which is a shame for products that need to be kept cool. And this time there were no small samples, I found that regrettable.
