wow great read and amazing tank.
You mentioned in previous post about your PH fluctuations. How does a huge drop in PH not affect your fish. I am a complete noob to planted tanks but why does your PH drop so much over a period of hours and what was your solution to this issue.
How much does your ph fluctuate now? I am planning on a large planted tank and adding an asian arowana to the tank. It will not thrive with ph fluctuations so I wanted to know what I need to do to avoid this. still doing lots of research and have no yet come across PH fluctuations in my research.
Again, awesome looking tank and will be checking in for further updates.
