I just looked up the product and I've been using it. In my head it was 'Flourish Excel' and the Seachem threw me off. Anyway, the 'successfully' in your subject line also kept me silent. I haven't had problems with the product but nothing outstanding either. I don't think it did much of anything for the 29 gallon tank I used it on daily for 3 months. And I used the recommended dose or just a bit less. And I have a HUGE container of the stuff (weak grin). I don't do CO2 injection in my planted tanks and wanted to see if this made a difference.
