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

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).

Unfortunately once again very slow shipping. In my opinion, the products suffer from it. Surely the carriers are traveling in reverse.

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 received daphnias 3/4 dead. I think the transport was too long because it was delayed. I give an average rating but it is probably the carrier that I should blame for this.

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.

Sorry for this note because your product arrived very late, impossible to know if the live bacteria are still alive ??? Therefore, I cannot judge the quality of your product :-(

Package received quickly, protocol followed to the letter, for now no visible macro life to the naked eye, but I hope it will come. Upon delivery, the bottles were very cold, I hope that didn't kill the micro and macro fauna... I will wait three weeks to form a definitive opinion. Thank you anyway, very good service...

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.

The chosen carrier "UPS" is unreliable. Always excuses for late deliveries. I hesitate to recommend Daphbio products just because of this!

Reliable and serious site, but the anti-cyano product (fresh water) didn't completely get rid of it... it's a shame considering the price.

Response from daphbio
Hello,

Thank you for taking the time to leave a review.

First of all, it's important to look for the cause of cyanobacteria development in your aquarium. Then, if cyanobacteria return regularly, it may be linked to your technical floor, your lighting, or certain water parameters.

Don't hesitate to send us a photo of your aquarium - we'll be delighted to help.

Best regards
Customer Service
