@Randy Holmes-FarleyI’m on page 7 of the prime doesn’t work thread. Why is my alk 20? Ph dropped to 7.85. Fish then not having as hard a time. I think prime works by lowering the ph! Then the ammonia is less toxic on its own. Why was an entire bottle of fresh bacteria not enough but a dose of NaOH to bring the oh back up and one dose of cycle kicked off the cycle in 6 hours dropping ammonia to 0.25. Hoping zero in the morning. Well science says prime doesn’t detoxify ammonia but it sure drops the ph which does.
