Really this is the best product, I've been lossing my fishes whenever I change water, but after using this my all fishes are safe.

No.1 Product for aquarium , to keep water cycled ,to maintain nitrogen cycle, to erase ammonia, nirite and nirate which is harmful for fish.This Api quick start instantly start the nitrogen cycle which is good aquarium lives and eventually increase their lifespan as pet in aquarium.Thanks Amazon and API.

The media could not be loaded. It really works...like in a matter for 5 to 6 hours the water quality started to improve! IDK if you can see it in the video but the water looks crystal clear to me even without the light, I can see the background poster of my fish tank very clearly!Plus its VERY GOOD FOR your FISH! just run it atleast for one week before you put fish in.In the bottle it says you can add fish instantly but that's actually not advisable, you need to give a minimum of one week for the tank to cycle properly to form the good bacteria! I'm waiting for my week to get completed and then I can start adding the fish

Best nitryfying bacteria for aquarium life.

Nice packaging and very fast delivery and original product

Good quality productResults are identicalGood quick result

Water quality improved a lot. my water was a lot cloudy and full of small particles of fish poop which got 100% cleared within a day of using API quick start solution.

Oh my god thank you amazon you saved a 100 fishes lives I put this quick start and my fishes stopped dying and the bio filter had stated it's growth only in an hour. If you tried to start the bio filter naturally it would take you a whole week. It was my mistake to put the fishes in the tank as soon as I received the tank.
