I did a 70-75% water change on Friday to my 20 gallon and I tested on Sunday I had 20 nitrate and .25 nitrite. I just finished testing and my nitrite is finally at zero and my nitrates are 10-15. Now on the other hand my 10 gallon is a little out of control. I’ve been adding 2mL of pure ammonia this whole week and I did it previously but I stopped due to not having time to take care of the 10g. I just tested it and my ammonia is off the charts and my nitrites are 2. Should I lower to 1mL of ammonia ?
