I think my 15 gallon planted tank is cycled. My betta, Phinneas, has been hanging out in my 5 gallon quarantine tank for the last 4 weeks while I have been setting up his future home. I am wanting to move him to the larger tank this week but I don’t know how to accomplish that without causing him harm due to very different water parameters despite all of my water coming from the same source. The Fluval Stratum substrate and the plants have significantly altered the parameters of the larger tank. See the chart below for additional information.
Additionally, I noticed the water in the 5 gallon tank has been sitting at .5ppm ammonia every time I’ve tested it in the past week despite water changes. After a 50%ish water change last night to try to lower that number, then seeing the same number today I decided to test my tap water. Found the problem! My tap tests at .5ppm ammonia.
As a result of these numbers, I’m looking for advice for two questions:
1. How do I safely transfer Phinneas to his new home?
2. How concerned should I be and how do I combat the ammonia that occurs in my tap water?
Thanks in advance for any insight!
