GFO

[STEVE]

I have a question concerning GFO...Why is it that I can rinse my GFO for 10-15mins, the water is crystal clear, yet later in the day after I have the reactor online in the system, I get a brown coating in the skimmer and in the skimmate and even in the sump? I think I'm rinsing pretty well.......Anyone else with the same issues/fix for this?

I have the same issue with carbon.

[Incredible Corals]

If it's tumbling a lot it will break down and create that dust. Is it tightly compacted in the reactor?

I have the same issue with carbon.

 

What type of carbon are you using? Cheaper grades of carbon will create a lot of dust. It's worth the extra cost for high grade carbon to protect your tank and fish (especially tangs).

Just dancing on the surface, not tumbling at all.

Carbon fron brs. The next step below rox 8.

What I do after I rinse, I take a piece of 50 micron filter material and cover the effluent till the water runs clear, usually takes 2 times to get it all. I also open the pump up all the way to get a good flow going

I will try that! Thanks

How much rinsing does everyone do? I used to just install the new stuff and run it full blast with salt water until it ran clean. Usually about 2 quarts worth. I never noticed any black and/or rust stuff on the skimmer or elsewhere. I'll check a litle more carefully next time I change/install gfo or carbon.

[Marc Weaver]

I get that in the skimmer too, Steve. Must be the fines that we cannot see getting collected in the skimmer. I haven't had them in the sump, though.

[STEVE]

The only thing I can think of is I'm not rinsing aggressive enough....long enough, just not with the valve opened up as much to really get that "tumble up from the bottom"

I had the same issue with GFO that's why I use Biopellets now. I could not be happier but the break in period is not a ton of fun

[rocko918]

oh god you are running GFO again?

 

 

 

 

 

 

 

 

 

 

btw, just busting on you.

[STEVE]

trying to get them phosphates down in the 300 !

[STEVE]

How they got there in the first place is my question...thru food I guess.

[kjamaya]

I never have that problem. I give mine a quick rinse then throw it in the rector and let it rip. I use brs gfo.

[basser9]

A simple 10micron and 1 micron bag setup is a easy thing to do.

Never have i ever rinsed carbon or gfo,

Never so much as a hint of any fines in my system.

I rinse carbon in tap and run both GFO and carbon into a bucket until clear. Both reactor outlets are run 24/7 through a 100 micron sock.
