The startup protocol is underway at the end of S3, difficult to give an opinion at this stage, the salinity reaches 1028, it is not indicated how to reduce it?

Fast shipping and well protected. I learned about Daphbio products through some YouTube videos. Now I started using them in my marine aquarium and everything is perfect, and my corals are much prettier and colorful. Both the Daphbio Microfauna Booster and the Bacteroreef work great for me. I recommend it to anyone with a marine aquarium. I will buy again without a doubt.. I will buy again without a doubt

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.

Very satisfied with my testing kit for my tank which is already 16 years old and some live rocks date back to 2001. I will place a new order in three months. Thank you also for the little coral booster supplement.
