I Love mine. It works. :heartpump.
I bought my Reactor and a bucket of Phos-Ban GFO from petsolutions.com, but now I buy my GFO from BRS which is more cost effective.
It's easy to use, and depending on how high your phosphates are, it could take a couple or GFO changes over 3 months before you realize the full benefits of the product.
Be careful to follow the directions especially when changing the media and priming the reactor into a bucket before letting it flow into your sump. This lets the dust and residue to be removed before entering your tank and harming your system.
If your phosphates are really out of control, and you need to bring it down fast, let me know and I'll post a link to a product that will knock it down quickly.
Looking at your tank photos, I don't see your phosphates out of control.
Hope this helps.
