I have been running it in TLF Phosban reactor for about 3 weeks now. It made my skimmer go nuts the within the first 24hrs, and it started overflowing.
It helped lower my phosphates, but it has not had an impact on the green hair algae growing on my sand. It keeps growing, and I keep exporting!!! I was hoping it would help end the vicious GHA cycle.
I am curious to read your comparisions on the different brands.
