need help on decision to get a gfo reactor

[Big_Pun]

I'm not running carbon right now either.

I stopped using carbon and haven't noticed any differences, except that my skimmer pulls out more stuff...

I keep ROX on hand in case, but other than super polished water, I have not noticed any difference. I am always weary of allelopathy though.

Next time I'm going to try the HC GFO, the low cap works but if the results could be even better, why not?

high cap is the only gfo i use, the low cap is ok but runs out so fast
