Advice? gfo use

In my smaller reef tank, I use BRS high capacity GFO in a BRS deluxe reactor. I use carbon in the top third of the reactor. For me, it's always worked great.

 

When I used GFO it was always High Capacity in a dual reactor. I always ran slow flowith whereally you could jus barely see the top of the media kinda dance. Never any clumping.
I ran gfo in first chamber and carbon in the other.
If you do get the eBay stuff. Let me know how it works.

 

I used rowaphos what i liked about it is that it claims that it doesnt leach out what it has captured. But it is priced pretty high. Now i use brs gfo. Kinda want to try the ebay stuff.

 

I use the brs high capacity mixed with their rox .08 carbon in a avast reactor. Tumbles nicely. Till I forgot and it was in a month.

 

I am pretty loyal to the BRS carbon and GFO. I have two reactors and rotate them out (mostly because it's easier to just set the new one in and clean the old one later. Not scientific, just lazy). I have one BRS dual reactor and one Spectrapure dual. I don't notice a great deal of difference between the reactors but will admit to having the GFO and carbon bind up in them. I am guessing it is lack of head pressure as they are mounted about 3 feet above the water line over my sump. In any event, the GFO from BRS works well but I would admit to having to shake/loosen/unbind it far more often than I'd like.
Perhaps I will just go bigger on my pump as the MJ 1200's just aren't cutting it.....

 

Yeah, by BRS dual reactor acts the same way. Not enough flow to really handle what is needed. I don't even put carbon in the 2nd chamber any more, so it stays empty. The MJ1200 just doesn't cut it in my opinion, despite others swearing that it works well.

 

Maybe I just got a good pump. But I have had my BRS Dual reactor for around 4 years running 24-7 never any problems with go or carbon tumbling and I have never had clumping issues.

I actually barely have the valve open and I can get the media surface to just start simmering. Any more than that your just grinding media to dust.
Now I tried a single reactor with bio pellets. And that was a fail. Pump not strong enough to tumble pellets enought.
On the dual I always changed media every 4-5 weeks and cleaned the screens and sponges.
