I just did the same got rid of all my cheato been running reef interest po4x4 and just started couple weeks ago with there brand bio pellets reef interest did just come out with a combo go bio pellets so you only need 1 reactor

if ur just gunna run gfo or = i would run both and if ur gunna bp i would look into vsv dosing all the cool kids r doin it
I have been battling nitrates and phosphates for years on my tanks. They have been running for 10+ years so nitrate and phosphates have been leaching out of the rocks from time to time. I vodka dosed and used macro algaes for 4+ years and I always struggled with my phosphates. My nitrates always checked okay. Those methods could never keep up with the amount of phosphate being produced(I feed really heavy). I am now running GFO and macro algaes (about a 90 gallon tank full). The phosphates are starting to come down and the nitrates are staying down too. My recommendation is in order to control phosphate over the long term I would use some form of macro algae as well as a phosphate reducing media. I am intrigued by the new product listed above as that could be as good solution. In my experience macros and carbon dosing do a great job of removing nitrates but remove phosphate at a slower rate.
So your gfo isn't killing off your micro algaes? I thought when you're running gfo/po4 media, it'll eventually starve out all your algae?
Biopellets really arent that hard at all, but they're more for nitrates. Little more work when you first start, but for me right now, they run 24/7 and i just refill when they get low. Never have to worry about anything with them. I'd keep the cheato in there, its not going to hurt anything. Grab some gfo, reconnect the reactor and you're good to go. I'd definitely grab a phosphate meter as well, Hanna makes a very good one, digital, easy to read

And that's exactly what I thought would happen eventually. That's why I was thinking of removing the cheato once I put the reactor online.Since I put the GFO online, my chaeto has pretty much stopped growing and now I'm considering removing it. I think it is actually receding and therefore, putting phosphates back into the water.
I think its a balance between gfo and bio pellets. If i use to much gfo and my phosphates get too low, my bio pellets reduce in effectiveness for nitrate reduction.
Start slow with bio pellets and it will take time got them to become colonized and work effectively. Don't remove your cheato right away.
