API 56E First Impressions
Worked just as well.
The equation is already done for you if you buy Dr. Do not gravel vac or disturb the substrate. Fish are aerobic organisms that are susceptible to ROS. I have a 5 gallon tank, so that number was waaaay too high for me. I've using this for my betta for several years with every water change. This only applies to the 1st application. Initially this was used as a sample packet came with our aquarium.

API 56E Final Thoughts
No odor or discoloration.
My fish didn't appear negatively effected by it either. However, be aware that the dosage starts at 20 gallons. The aquasafe works instantly upon mixing with tap water. Use a heater and crank it to 82 degrees again without fish in the tank. The equation is already done for you if you buy Dr. I've used every product on the market and this is the most AMAZING MUST HAVE PRODUCT! I'll continue to use this product, especially after a good tank cleaning.
