Superb products.
Superb product. API is one of my resources for many of my aquarium essentials. Never had any problem with any of there items. Great value for money, with many products giving you size options for what you need. All products from medicated to water parameters and plant care. These products are made with an ease of understanding for what that purpose is and will help you on your fish keeping journey.

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.

Highly effective Improves water quality by maintaining bacterial colonies Easy to use... Rather than other products. Must to stepup a new tank.. also it is good to add once in month so replenish the bacterial colonies

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!
