High hopes shattered

I have a 55 gallon aquarium for years. I've always wanted to try an all real plants in aquarium so I purchased some and read to buy this food for them. I do a 20%

I have a 55 gallon aquarium for years. I've always wanted to try an all real plants in aquarium so I purchased some and read to buy this food for them. I do a 20% water change and follow directions with this fertilizer once a week for 3 weeks now. My water is clear and the plants aren't dieing but I have lost all 10 shrimp, my female and male betta, 2 guppies and 2 wag platies. That being said, I have had my tank for years and I have never had so many fish & shrimp die. It is either this fertilizer or something on the live aquarium plants. I am puzzled because everything looks healthy.

potentially deadly for shrimp

I had no idea this product was horrible for shrimp. Even some of my fish are acting weird after dosing it. Unfortunate waste of money

It has been 2 weeks and still haven’t received it. FedEx is a terrible delivery service and I wish they would quit being used. This is not my first issue with FedEx

It has been 2 weeks and still haven’t received it. FedEx is a terrible delivery service and I wish they would quit being used. This is not my first issue with FedEx. No details about the product since this would have been my first time using it. We will see someday.
