Review on 🐠 API Proper pH Powder: Achieve Optimal pH Levels for Thriving Fish in Aquariums - Ideal for Setup, Adjustments, and Water Changes by Robert Zander

Update: After about a day and a half my tank was about 50% less cloudy. I added water clarifier so I'm not sure if it did that or if it went away on its own. Changed from 2 to 4 stars. I used less than the recommended amount and it still clouded my tank. The bottle says the cloudiness filters out quickly, but that's not the case. I will probably need to change at least 50% of the water. I only gave it 2 stars because at least it didn't kill my fish.
