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

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€.

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.

When I placed an order, I was offered 4 free samples including the usual one, on the delivery note the 4 samples were listed but in reality there was only 1. I was told that it was normal because they were giving me a 15% discount.

I did not get the expected results, nothing is thriving in my aquarium, no bacteria on my stones, I am left with cyanobacteria and filamentous algae that continue to grow. With a rise in nitrate. Approaching 50 mg. Causing the loss of 3 fish due to the rise in nitrate. My disappointment, I was already between 25 and 30 mg and now I find myself at 50 mg. For the launch of my tank. It was effective at first. Following the rise in my nitrates, the reseeding brought me nothing.
