Considering Adding GFO Alongside With Pellets and Carbon

[Bblinks]

I am with you Kien, I like to flow different rates too. once a while I have no flow at all.

All jokes aside, I run rowaphos with my carbon off the same pump for my pellets and UV. I was always getting a 0 ppm reading from Hanna but since I got the ultra low range its showing up at 13 ppb. I will be running a bit more GFO ratio to carbon see if I can bring it down to 0. I really dont think its critical to have phosphate at 0 but since we are introducing phosphate into the tank all the time it wouldn't hurt to try.

I use to run a bunch of reactors, but keeping it more simple nowadays. Reactor for the pellets, but running GFO in first bubble trap, and carbon in the last one before return pump. Using the traps for these, allows lots of flow through the material, and from what I read you don't need to reactor them.

I change out GFO monthly, carbon mid and end of month.

I don't run gfo and run carbon passively. If I did start to run gfo it would also be passive in the bubble trap. The only reactor I run is a mr1 full of hydroton.

Now if I ran GFO into my reactor, is there such thing as adding to much?
With the pellets, I was told I don't need to change them out, just top it off because the pellets will dissolve away.
