What is the difference between regular and HC German GFO? The main difference is that HC is roughly 1.5 times more effective at removing PO4. It is also much more dense, thus requiring more flow than regular GFO. It also withstands more flow before grinding down to a fine dust. Low grade GFO quickly pulverises with too much flow.
 
As with all ferric oxide media, alkalinity levels may drop when used.
Be sure to monitor alkalinity and adjust as needed
Rinse well before use
 
Although this is HC GFO, excessive tumbling my still cause it to grind / dicintegrate and send GFO dust into your sump / tank. Unlike biopelets GFO must NOT excessively tumble in your reactor. Tumbling will cause some grinding.
 
USAGE: The amount used depends of the amount of P04 your system produces and what level you want to drop it down to. We recommend starting with 1.5 Tablespoons per 10 gallons and adjusting from there.

This is good quality GFO. I used to use the BRS version and the one thing I will say is that this is a lot dirtier and needs more rinsing than most I've ever seen. Results are good though and that's what is important.

Advantages: Long lasting
Works quickly

Disadvantages: Really dirty, needs extra rinsing.
