Mixed reviews.
The mixed reviews and its claims have made me worried about using this. However I put a half measure in. I found in some fish products you can have Armageddon so if in doubt don’t use it or use smaller measurements. I have no fish in the tank yet and I’ve been doing test strips. Fish in two weeks and water checks coming to satisfactory so must play some part. I usually use cycle but water tests for both have been good.

A Quick Start indeed...
Another excellent product from API which does the job as required. In this case it's Bacteria to add to the Filter to service the well-being of the tank water when setting up a fresh aquarium or adding new fish to an already established one.

The API QUICK START works like a charm! I used it when setting up a new aquarium, and it helped cycle the tank quickly with no ammonia or nitrite spikes. Super easy to use, and safe for fish—my water stayed clear and healthy. Highly recommend for both beginners and experienced fish keepers!
