### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Potent and works great for SPS growth
  

*by T***A on Reviewed in the United States on November 29, 2016*

I was turned on to Fusion by my LFS who had just gone to a Seachem training seminar.  I was using BRS 2 part,  but had to dose magnesium separately, which was a bit of a hassle.  Once I decided to give Fusion 2 part a try, I had to reduce dosing from 65ml down to 25ml per day.  That's how potent this stuff is.  I also like not having to worry about dosing Mg separately.  Great product and my SPS really started to grow nicely after starting to use it.
