Actually, ozone was the last thing on my shopping list due to concerns about potential health problems. However, in my battle against high organic matter in the tank, I've exhausted all other methods like Zeo, activated carbon, a large protein skimmer, and UV sterilization, none of which significantly reduced the organic matter concentration in my aquarium.
Until three days ago, when I introduced an ozone generator and used ORP to automatically control its operation, maintaining the ORP within the 360-400 range. Today, I cleaned the green hair algae from the live rocks with a teeth brush, and as some aquarists may know, this can really make the tank water look cloudy! Haha!
Then, I increased the ozone supply, and after three hours, I took a sample of water. In both of the images below, the water on the right side is from this sample. In the first image, the left side is the water from my tank three days ago, which appears yellowish. The contrast is quite evident, isn't it?
What astonished me is the second image. On its left side is the RO water with TDS at zero, and it's not as clear as the water from my tank right after I cleaned it. believe me I used different view angles and light sources, the comparisons have same results.
So, does this mean that even the RO/DI water I painstakingly produced with zero TDS still had residual dissolved substances? And anyway all of these were effectively removed by the ozone generator! It's truly remarkable how powerful ozone can be.
