I am not sure why but it looks like every other day I need to clean my glass, and my sand bed turning greenish.
As far as I know it's brown algae?
I just check my RODI water, the digital device shown 0 tds, I also did "Total chlorine free chlorine" paper test, also shown 0 ppm.
Any one have an idea why is that happen?
I am going 15% water change every week, it's 180 gallon total volume.
