About API QUICK START Nitrifying Aquarium Bacteria, Allows Instant Addition of Fish and Maintains Active Biological Filter
75% praised for its ability to control algae growth, though 25% noticed some regrowth.
I accidentally put Quick Start in my 75 gallon tank while doing a water change and noticed that the cyanobacterias growth had been stunted in just two days.
I used the product to jump start the cycle during a pond emergency where the liner sprung a leak and added old filter media. However, there was an immediate ammonia spike that killed over half of the koi.
91% found it easy to dose and apply
I found the instructions on the side of the bottle easy to follow and it helped with the startup process of my past aquariums.
I added the appropriate dose of the treatment and by the end of the day, the ammonia levels had decreased to a safe level.
This is a must-have when setting up an aquarium as it prevents fish loss and maintains an active biological filter in an established aquarium with live nitrifying bacteria.
After using Quick Start in water changes, I got a bunch of snails and stopped vacuuming the substrate thoroughly. As a result, the cyanobacteria is now 95-98% gone.
80% appreciated its safe and gentle formula, while 20% reported some fish stress.
After a week of using the product, I tested the water and found that everything was within healthy water parameters.
After adding the appropriate dose, I noticed that the ammonia levels decreased to a safe level by the end of the day.
I have always used this formula for fresh water aquariums as it is weak on salt water tanks.
The product is deadly to freshwater fish.
86% praised for its ability to eliminate unpleasant odors
This product always helps me balance my tank shortly after treatments are completed, whenever I have to shock my tank due to an illness outbreak.
80% appreciated its ability to replenish essential minerals, but 20% noticed some/mineral imbalances.
I wish the label mentioned that adding fish food or organic matter along with this product is more effective for a new tank.
