Reactor MJ powerhead split question (1 Viewer)

So - I was running 10 tbls GFO per the BRS calculator in the TLF reactor for the last week or two- based on the BRS GFO - granular calculations on a 40 volume tank.

Got my package from BRS today which included my high capacity GFO and Rox 0.8 carbon

So - I emptied out the low GFO out of the TLF reactor that I had been running and added 10 tbls high capacity GFO (BRS calculator called for 5 tbls) and then mixed it with 5 tbsp Rox 0.8 Carbon (BRS calculator called for 4 tbsp)

I wanted to go 2:1

Lets see how this works in the Two Little Fishies Phosban 150 reactor - so far - so good
 
I was really hoping someone would find the vids and post here. :)
Got all my stuff! Man does BRS ship quickly!

I love getting a box of fish goodies in the mail : )

I have the MJ600 wide open on the TLF running the GFO/carbon mix - I cant find anything out there for how to tweak the powerhead settings when mixing both in a TLF. Is wide open good?

Ironically anytime I used GFO I always had the best results when I mixed GFO and carbon together. Makes it so much easier to run for me, 2:1 ratio is what I always did (no real logic to it) and mixed it in a bowl before loading the reactor.

To clarify, it is 2 parts carbon to 1 part gfo, according to the video.

Crap - I went GFO/Carbon 2:1 based on Marty's post

Think I should just add some more carbon?

TLF reactor currently:

Don't let it tumble!!!! The gfo will grind the softer carbon into fine particles which will get into the tank

Hee hee - just watched another BRS video and figured that out. Was only tumbling for the day. I turned flow down to almost nothing and all is sitting happy.

Still not sure if I should add more carbon since I did the 2:1 backwards

Is it possible to overdose GFO? I went with 10 tbls high capacity GFO (BRS calculator called for 5 tbls) and then mixed it with 5 tbsp Rox 0.8 Carbon (BRS calculator called for 4 tbsp)
 
Use the foam pads to hold it all in place and then crank the flow. With the pads in place one above and one below the media, the media shouldn't move even with the higher flow

Pushed the foam pads down on top of the media but once I opened the flow - they kept flying to the top. I improvised with a larger tube going around the inlet tube to hold the sponges down and now I can open the valve wide open : )

The ratio is really all about 1. Having enough carbon in the mix so the gfo don't clump (your current mix is likely more than enough to prevent clumping) 2. Most systems typically need more carbon than gfo 3. Carbon is was cheaper than gfo 4. The exhaustion rate of gfo vs carbon. Basically once you get into a grove use as much gfo as maintenance just to keep the po4 beat down. If just starting out, your po4 is likely higher to a hotter mix of gfo to carbon might actually make sense for right now.

In the end, mixing them is all about not thinking too hard about it - that's the great part of mixing them is it simplifies things (for most people.... Not our president apparently....:) )

Is the High Capacity GFO from BRS worth it? I have always used the regular GFO but am still stuggling with bryopsis algea.

If you want to get rid of bryopsis, do it by raising your mag. You can raise it with Mg supplements from BRS (use both Mg Sulfate and Chloride), then, when above 1700, start dosing Kent M and that should get rid of it.
