I've also seen people run two reactors off of one pump (i used to do this a while ago). Myself, I have the room in my sump so I just run separate reactors with separate pumps for two reasons:

1. I like to change out my media on alternating intervals. That is, on the 15th of every month I change out my GFO while on the 30th of every month I change out my Carbon. I do this to reduce my one time maintenance (ie, so that I'm not spending too much time changing out both media at once). I also like to spread the effects of the changes.

2. I like to flow different rates through my media.

At any rate, I've seen it done many different ways to suit peoples needs.

You're welcome. I'm happy to see that things are working out now. See, I told you not to panic :-) Now just sit back and let your tank settle in :biggrin:

:pop2:

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

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.
