Hello everyone, I have had to restart my tank due to unforeseen personal issues. I have now been able to get it back up and running. It is a 26 Gallon Red Sea Nano Peninsula. I am now about 6 months into it with currently only rock and fish, I introduced new fish over the course of the 6 months, (2 clowns, 1 Banggai Cardinal and a yellow goby). I feed 1/4 of a Mysis shrimp cube daily and sometimes a bit less depending how I cut it and do about a 5 gallon water change every weekend. I clean the sponges once a week and replace filter floss during the time as well. It seems that no matter what I do, I cannot get it under 40 and controlled. What do you think I should be doing?
