Who runs carbon gfo and biopellets?

[Vapour1ze]

I'm so sick of the mess changing my gfo and carbon. I wish it was simple like the biopellets. I'm just wondering how many of you keeping sps don't use carbon or gfo. Pros cons. I've always heard mixed reviews. But seriously. Running all three for life? Or just biopellets ok?

Biopellets are really good at reducing nitrates and help somewhat with phosphate. I have been running pellets for a year and a half, but couldn't keep phosphate where it needs to be, so I also run gfo too. However, my GFO lasts a really long time, something like two to three months. I throw carbon in a filter bag every now and then.
