Zeovit + Bio Pellets

Would i still need GFO & carbon if i was to go with both ?
seems like my sump will be full of reactors lol

I'd say yes to both unfortunately. Carbon does its own thing and isn't replaceable by pellets or zeo, although is space was a concern you don't really HAVE to run carbon in a reactor, a filter bag passive in the sump in a high flow area can work well apparently.

I found the pellets were awesome on their own for reducing nitrates, but did not do much for phosphates, and if I ever did pellets on their own again I'd still run GFO alongside. I think they do reduce phosphate to an extent but at a much slower rate than they reduce nitrate.

Good point. I do run carbon and rowaphos with pellets and zeovit. Pellets take away both nitrate and phosphate at the same rate, but once one is depleted the other element tend to stick around which in 99percent of the case it's phosphate. A bit of rowaphos will take care of the rest. I also found that Lps and clams don't like it when every thing is at zero so if you have a mixed reef it's better to keep a bit of phosphate just so they are happy.
