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.

I scrupulously followed the anti-cyano protocol with daphbio, which is 100% effective, but it didn't work. Water with nitrate 2, no phosphate, no sand, no sediment, I can't get rid of it. Despite this, I continue to use their bacteria for up to 1 month, as specified in the instructions.

Hello My delivery so the resettlement kit smelled as if it was spoiled. I suspect that the product has not survived the hot temperatures. I then received a new order which was protected against the heat with a cold pack, which is how you have to pack a product like this and not just in a cardboard box.

Hello, My only complaint is with the delivery, not with your products. I have been a loyal customer for many years. The Colissimo took a week to arrive in Corsica. I don't know if this has any effect on the quality of the product, it's usually teeming with life, but in this case it was rather dead. That won't stop me from recommending it again. Best regards Guillemot fabrice Ps: hello to Benoît, it's been a while since I've had him on the phone, I hope he's well.

I'm quite happy with the products despite the fact that the free delivery isn't to my address; you have to collect the parcel from a point relay; when you have difficulty getting around it's inconvenient.

The good reviews are far too good, even misleading, compared to the real effectiveness of the product and the services offered by daphbio. I had to pay additional delivery charges that were not foreseen at the reception. And I had to fight for 1 week with UPS to get my parcel back (it was supposed to be delivered in 48h...). Don't waste your time with Daphbio, they won't do you any good.

Strangely enough, the anti-cyano bacteria product I received was not as effective as before, when the cyano bacteria disappeared in 4 days. Now, not only does it remain, but it's starting to thrive again.

I have already used daphbio microfauna and meiofauna as well as the booster and bacteria and I had had a fantastic restart effect, snails, shells, copepods, etc… this time, unfortunately, I had no effect… nothing! tank recently restarted with three fish and a coral survived, I entered everything as per protocol, turned off lights and skimmers, turned off UVC filter, left only the movement pumps for a day and nothing ... nothing happened 🤷‍♂️ after more than 15 days no new guests not even microscopic.

Too expensive in spite of an acclimatization in the rules of art... My package arrived one day before the weekend, the relay point being exceptionally closed on Monday (I played bad luck???), I could not get my package that 7 days after its arrival, so hecatomb

Upon receipt I followed the protocol available on the site but so far I see no microfauna this develop... 🤔 I am really septic this time on the quality of the bottle received. Concerning the bactoreef it does the job.

My order arrived at the end of the week and the relay point was only open on Saturday at the beginning of the day. I don't know if it's the cause but the number of alpines could be counted on one hand. Today, 1 month later and with the breeding of phytoplankton thanks to the second bottle, my daphnia population seems to increase.

Product of incredible and exceptional quality, except for my last order on the other hand delivery service really not top and after sales service in case of problem even worse. My package took a week to arrive and upon arrival no surprise the product containing the meiofauna was good to throw away, nothing alive everything was dead at the bottom of the bottle. According to the soap they send to the United States. I can't imagine the state of the product when it arrives. The other products were able to withstand the delay in delivery without the quality being altered.
