I had it dialed down so you just saw a few particles bouncing on top. Much slower and it would have been shut off. The problem was it started to bind together within a few days from reacting to calcium. Then no amount of pressure would budge it.

It was the phosguard that ground up. But the GFO is messy for sure.

As for the premium GFO, i noticed it was a bit harder than the regular version. I haven't really kept tabs on the stuff since it works just fine for me. I'll take a look next time I swap out the stuff.
Does your bind up? Mine turns into a dense block within days.

It takes about 4 parts carbon, 4 parts nitrogen and 1 part phosphate (and various other stuff at small levels) to create biological biomass, at least I think thats the formula I remember from biology class. The beads are the carbon source, so you deplete phosphate before the nitrogen as the bacteria multiplies. So they should work on both. But I am still skeptical. It does look like a controllable carbon source for beneficial bacteria that might be more dependable than vodka.

Nope. Not all. Although it does get clogged from time to time. But that's mostly because I have no baffles in my sump or good mechanical filtration. It clogs with detritus not the premium GFO

May have to try some of that. It's just kind of expensive.

I use cheap panty hose as cheap filters and it works wonders. Might help.

It is a bit more expensive but I was able to use less and have it last longer than the regular stuff.

If it doesn't pack up, it is certainly worth it.

The regular grade didn't pack up for me either. I just switched to the High Capacity grade since I was running a large system with a small/regular size reactor. I wish there was a way to try samples and see what works best....

The HC GFO actually costs about the same as the other since you only use half as much. I did have trouble with the GFO clogging or clumping when i was carbon dosing.
