It worked for me... I got 2 bottles of purple and one bottle of pink for my xl425... If you follow the instructions, which clearly states that is important for product to work, in 2-3 months you will get a coralline explosion... my tank has been running for a little over 3 months and over 75% of my rock is covered in coralline... I started with 175 lbs of Billys dry reef rock... Its all over my overflow and on the rubble rock and return lines in my refugium... I 100% would say this product worked in my case and would purchase again... ill get some updated pictures today in some good lighting... problem is people are impatient and think this stuff works in a matter of moments and stare at their tanks like its acfually gonna grow in fromt of you... clearly states on bottle takes several weeks, in most cases months at the right temperature, spectrum, and water quality... I used 0 live rock... all dry rock
These pictures were taken at the end of october... My tank officially started running August 3rd... I will get some clearer pictures today... I aint no rep either... I just bought the stuff on Amazon and used it as it said to...
I have it included in my build thread
