Bio pellet reactors and where must drain

[Vett espinal]

I have a HOB protein skimmer , iam using a gfo reactor and let the water from it drain in to my refuguim its hanging on, i wanted to add a bio pellet reactor but everyone says it needs to empty in to my protein skimmer , i reall dont have way to that i can have it drain right next to the input of the pump , but its still in my main tank , so where is it safe to empty the out end of the REACTOR in to , can i just drain in to my refuguim also , or can i dump staight in to tank next to pump pick up , or should i not add a bio pellet reactor if i dont have a sump or can i run the bio pellets in to the gfo REACTOR, one in to another , if so which is the best order to put em in , Bio pellets first then GFO then out in to tank or what ? Please help , iam alreading running a GFO reactor into my refuguim and would like to just add another for biopellets and run in unison thinking GFO into Biopellets, and drain into HOB refuguim , but everyone says you have to drain. Biopellets into protein skimmer area, i can possibly drain in the area of pick but that is also already in my tank , Does anyone have a idea if just going from gfo to bio pellets and then into my refuguim which is HOB be ok or will still cause the brown film at bottom of tank ???

Welcome to reef2reef
I dont use biopellet, but from what I have read its not a strict necessity. Lots of folks use biopellet reactors straight . I read more challenges with dialing diwn the right amount. So, go slow. Just curious whats your setup?

I'd recommend using biopellets with a sump and drain in front of the skimmer. I'm sure you "can" run biopellets without a sump but manage your expectations accordingly. Assuming you don't have a sump, liquid carbon dosing would be much easier and more controllable.
