Dual BRS GFO and Carbon Reactor question

If you have a sump, that would be the ideal place for it. I run mine in sump with carbon and GFO loaded in the same reactor.

 

I wouldn't put pellets in line with the carbon and gfo. As the only way it would work is to put gfo and gac in chamber one and pellets in chamber two. Because the other way around the bactera would clog up the GAC and GFO. But this would be counter productive as the bactera needs the po4 that the GFO would filter out. And then the pellets would basicly be doing nothing.

 

You can run them both just don't do it in line with each other for the above stated reasons.

 

Many people cure their phosphate issues when running biopellets because the chemical process between the bacteria and the nitrates consumes a small amount of phosphates. If you didn't have a significant phosphate issue, biopellets may be the answer for you. If you did, you may still need to run GFO, but probably less than you did before.

As Bill said, I wouldn't advise it for exactly the reasons he states. I would recommend two separate reactors. That also gives you independent flow control on each reactor.
